Martinez, California – The Contra Costa County District Attorney’s Office has filed murder charges against a Richmond man accused of setting a house fire that killed three family members and critically injured a fourth.

Sergio Ivan Rivera-Vega, 32, faces three counts of murder, with special enhancements tied to the deaths of an adult victim and two minor victims. A fourth victim, an adult woman, remains hospitalized with serious injuries; Rivera-Vega is charged separately with arson causing great bodily injury in connection with her injuries. All four victims are related to the suspect.

As previously reported, Richmond police and firefighters responded to a house fire in the 200 block of 15th Street on the evening of August 18th, at approximately 8:58 p.m. Detectives investigating the blaze identified Rivera-Vega as the person who intentionally set the fire. He was arrested and booked into the Martinez Detention Facility on August 19th, and the investigation continued in the days that followed.

The case was submitted to the District Attorney’s Office for review today, Friday, August 21st, and charges were filed with Contra Costa Superior Court that same day. If convicted, the enhancements attached to the murder charges would carry a sentence of life without the possibility of parole.

“This fire is devastating for the entire family,” said District Attorney Diana Becton. “Knowing the suspect is related to the victims — including two children — makes this loss even harder to comprehend this senseless act. Our thoughts are with the family and the community affected by this tragedy. Just know that my office is committed to following the law and holding the suspect fully accountable.”

Rivera-Vega is scheduled to be arraigned on the charges on August 24th at 1:30 p.m. at the A.F. Bray Courts Building Annex in Martinez. He remains in custody in lieu of $2,500,000 bail.

Following $55,000 loss, year-long investigation; worked remotely

By Pleasant Hill Police Department

After a year-long criminal investigation, felony charges have been filed against a former employee for the Pleasant Hill Tourism Improvement District, known as Visit Pleasant Hill, in connection with an embezzlement and bribery scheme.

In July 2025, the City of Pleasant Hill received a report from a contracted company regarding possible fraud involving former Tourism Improvement District Vice President of Sales and Marketing Sibongile Viola Ncube. The Pleasant Hill Police Department subsequently began an investigation.

The Pleasant Hill Police Department determined that Ncube overcharged invoices and bills paid by the Tourism Improvement District (PHTID) and received unauthorized monetary kickbacks. The fraudulent activity occurred between September 2022 and July 2025 and resulted in an estimated loss of approximately $55,000.

The Pleasant Hill Police Department requested assistance from the Contra Costa County District Attorney’s Office, including a forensic review of bank statements and related financial records. Following its review, on July 24, the Contra Costa County District Attorney’s Office filed two felony charges against Ncube, 641.3(a) PC – Commercial Bribery and 508 PC – Grand Theft Embezzlement.

Ncube is scheduled to be arraigned in court later this month.

The PHTID was formed by the City Council in January 2017. According to the Visit Pleasant Hill 2024-25 Annual Report the District assesses all lodging businesses available for public occupancy located within the boundaries of the City of Pleasant Hill. According to the organization’s LinkedIn profile, it is the “Destination marketing organization advancing Pleasant Hill’s visitor economy,” which, according to their Facebook page, “provides official visitor information and promotes local businesses, experiences, and events in Pleasant Hill, CA.”

According to her LinkedIn profile, Ncube worked in the position with Visit Pleasant Hill remotely from May 2023 to August 2025, after starting as Director of Sales & Marketing from April 2020 to April 2023. She has since worked remotely on a contract as Director – AI, Sales & Marketing for Aspire Hospitality from Aug. to Oct. 2025 and now works as Director of Sales & Marketing Omni Hotels & Resorts, full-time since Oct. 2025.

She earned a MBA in Hotel, Restaurant & Tourism Management from Oxford Brookes University in 2003 and an Associate’s degree in Hospitality, Restaurant & Tourism Management from City St George’s, University of London in 2000. Ncube also earned a credential in Advanced AI in Marketing from the Digital Marketing Institute in 2025 and a Diversity Equity and Inclusion Certified Professional from Destinations International Issued in 2022.

Her Facebook page shows Ncube’s last post was in June 2025. It also shows she lives in Los Angeles, is the Founder and CEO of My Black Beauty Box and The Black Book Consultant, still works for Visit Pleasant Hill, and references the Bible verse Isaiah 55:5.

According to an undated report by Black Meetings & Tourism, “Viola has held VP and Director roles specializing in the luxury hotel brands, holding key positions such as Regional Sales Manager with Accor Hotels (3200 hotels), then moving to Director of Sales with the prestigious hotel group Red Carnations (16 global hotels) before joining US based L.E. Hotels (400+hotels) as Director of Business Development – EMEA. Viola then joined the luxury Pineapple Hotels firm as Director of Corporate Sales before being head-hunted in 2011 to set-up Global Hospitality Services for a private investor, a hotel sales & marketing representation company, where she held the position of Vice President.

“Viola Ncube founded The Black Book Consultant in 2017, a boutique full-service management, sales & marketing consulting agency specializing in a curated selection of luxury hotels and DMO’s worldwide. The Black Book Consultant has since acquired several contracts within its first few years of operation, including managing the $300 million dollar opening of Svart.no and Melody Maker Cancun. Viola is currently contracted as VP of Sales & Marketing with Stay Pleasant Hill, the tourism district for the city of Pleasant Hill, CA.

“In 2012, Viola founded iROCK! UK, a social enterprise, an empowerment program, mentoring women into employment & business enterprise.”

The Pleasant Hill Police Department extends its appreciation to the Contra Costa County District Attorney’s Office for its thorough forensic review and assistance throughout the investigation.

Committed during burglary while out on conditional release; pleads not guilty

Faces life without parole

Now, labeled by Homeland Security as “criminal illegal alien”

By Ted Asregadoo, PIO, Contra Costa County District Attorney’s Office

Martinez, California – On Wednesday, August 12, 2026, the Contra Costa County District Attorney’s Office filed a felony complaint charging 36-year-old Marcos Eduardo Iriarte-Valdez of Martinez with the murder of Todd Stewart of Martinez, who was 68 years old at the time of his death.

On August 6, 2026, at approximately 5:10 pm, Iriarte-Valdez stabbed Todd Stewart to death with a knife while committing a residential burglary. The Martinez Police Department quickly identified and located Iriarte-Valdez with assistance from the public and through multiple investigative sources. This included video surveillance capturing events related to the crime, as well as physical evidence processed by the Contra Costa County Sheriff’s Office Crime Lab. (See related article)

On August 11, 2026, the Martinez Police Department presented the case to the Contra Costa County District Attorney’s Office for review. That same day, the District Attorney’s Office filed a criminal complaint charging Iriarte-Valdez with one count of murder for the unlawful killing of Todd Stewart.

The complaint also includes three additional enhancements to the murder charge:

  • Killing during a burglary: The District Attorney’s Office alleges the murder took place while the defendant was committing, attempting, or fleeing a burglary. This special allegation, if found true by a jury, means the defendant could face life in prison without the possibility of parole.
  • Use of a knife: The complaint alleges that Iriarte-Valdez personally used a knife during the commission of the crime, which qualifies as a serious felony enhancement under state law.
  • Committed while out on conditional release: At the time of the killing, Iriarte-Valdez was out of custody on electronic monitoring, as ordered by the court, in a separate, unrelated burglary case.

Contra Costa County District Attorney Diana Becton said, “Our office will pursue this case with diligence and integrity to hold Iriarte-Valdez fully accountable under the law for this devastating act of violence. Our thoughts are with the victim’s loved ones and the larger community as they navigate this unimaginable loss. Our Victim-Witness Assistance Program is available to guide the family members through the criminal justice process and connect them with the services and support they may need.”

Iriarte-Valdez was arraigned Thursday in Contra Costa Superior Court, pleading not guilty to the murder charge and denying all enhancements. Judge David Goldstein, who presided over the arraignment, called the defendant “a risk to public safety” and ordered him held without bail. The case returns to court September 9th at 8:30 am before Judge Michael Nieto in Richmond to set a preliminary hearing date.

According to charging documents, the suspect faces life without parole for the murder charge. 01-26-04140 – Charging Document

As previously reported by FOX News and ABC7 Eyewitness News, the Department of Homeland Security has labeled Iriarte-Valdez a “criminal illegal alien” as the agency had placed an immigration detainer on him on Sept. 23, 2025.

In addition, according to the California Globe, “On August 8, 2026, ICE placed a detainer on him with the Contra Costa County Jail.”

Has history of arrests; released from custody Thursday back in custody Friday

By Ted Asregadoo, PIO, Contra Costa County District Attorney’s Office

Martinez, California – An Oakland resident faces five felony charges for his role in an organized theft ring connected to a series of burglaries in Concord.

The charges stem from a series of burglaries that occurred in Concord between April and July 2026 located in the Ygnacio and Clayton Valley region. Concord Police found that an organized group of juveniles carried out around 37 burglaries in that area. Richmond Police arrested the juvenile suspects for vehicle theft in May, and a subsequent investigation revealed they were part of a fencing operation led by 37-year-old Wuillian Heriberto Cordova-Cubias. Fencing operations are a hallmark of organized theft rings, which buy stolen goods from thieves and resell them to the public.

On August 5th law enforcement officers from the Concord Police Department, Oakland Police Department, and U.S. Marshals Service executed a search warrant at Cordova-Cubias’s Oakland residence. When officers entered the home, they located numerous items of suspected stolen property, including at least 500 power tools.  (See related article)

After law enforcement referred the case for review, the Contra Costa County District Attorney’s Office today filed a complaint in Superior Court against Cordova-Cubias. He faces the following charges:

  • Receiving stolen property, including power tools, survey equipment, motor vehicles, and pipe inspection equipment
  • Two counts of receiving stolen motor vehicles (a utility ATV and a forklift)
  • Unlawful firearm activity
  • Conspiracy to commit a crime with juvenile conspirators

All charges include enhancements that increase the potential penalties.

District Attorney Diana Becton said, “As organized theft offenses have increased, my office has responded by building an effective Organized Theft Unit that works closely with law enforcement to file strong cases we believe we can prove beyond a reasonable doubt in court. Concord Police Department’s thorough investigation into these burglaries and the fencing operation reflects the kind of collaboration that holds individuals accountable.”

Cordova-Cubias was in custody at the Martinez Detention Facility and will appear for arraignment in Contra Costa Superior Court in Martinez on August 10th at 1:30 pm. According to the Contra Costa County Sheriff’s Department, as of Thursday, Aug. 6, 2026, at 09:28 AM he had bonded out of custody. UPDATE: However, according to Asregadoo, he’s “not out of custody anymore. He was brought back in earlier today.”

According to localcrimenews.com, the five-foot, eight-inch tall, 240-pound Cordova-Cubias is Hispanic and has been arrested at least five other times for guns, drugs and violent crimes including battery and threats of violence, and receiving or concealing stolen property.

According to the Oakland Police, he was arrested in February 2020 “after a month-long investigation…charged…with possession of a firearm, possession of controlled substance, and possession of roughly 250 stolen power tools, worth an estimated $300,000. The suspect sold some of the items at flea markets in Oakland and San Jose.” (See video)

Pinole man sentenced to 50 years to life for 2024 murder of ex-girlfriend, mother of their son

By Ted Asregadoo, PIO, Contra Costa County District Attorney’s Office

Martinez, California — Today, a Contra Costa Superior Court judge sentenced a Pinole man to 50 years to life in prison for murdering a woman just 10 days after she ended their relationship.

On May 7, 2026, a jury found 39-year-old Jeffery Kendall guilty of first-degree murder in the killing of 30-year-old Brittany Elizabeth Ligdis on February 16, 2024. Jurors also convicted him of child endangerment for placing the couple’s young son in a situation that threatened his safety. Before trial, the defense successfully petitioned the court to try a separate charge — possession of an assault weapon — before a judge rather than a jury.

The homicide

A 911 call captured the murder as it unfolded on the morning of February 16th. The victim, Brittany Ligdis, told dispatchers that Jeffery Kendall had broken into her home and that she was hiding in the laundry room with her son. About 90 seconds into the call, Kendall entered the room. Brittany pleaded, “Let go of me” and “You’re scaring him,” before screaming, “Stop it.” Kendall then shot Brittany in the head. The couple’s four-year-old son cried “Momma” and fled the room; Kendall fled the scene shortly after. Responding officers found the victim dead of a gunshot wound to the head.

The case for a harsher sentence

Deputy District Attorney Tylyn Wells described the killing as “an execution in front of a 4-year-old child,” arguing it was not the product of “a mental break” but a familiar pattern in domestic violence cases: a threat that escalates once a victim decides to leave. Citing these factors, Wells asked the court to impose a sentencing enhancement, raising Kendall’s exposure to 50 years to life.

During the bench trial on the weapons charge, Judge Glenn Kim found Kendall guilty of possessing an assault weapon — a 3D-printed pistol capable of semi-automatic fire — and ruled that six aggravating sentencing factors tied to that charge were true.

The sentence

At today’s sentencing hearing, Judge Kim called the case “one of the most difficult” he has experienced. He imposed two consecutive terms of 25 years to life, totaling 50 years to life, and barred Kendall from contacting his son, with limited exceptions subject to court approval, until November 2035, when the boy turns 16.

Kendall remains in county jail awaiting transfer to the California Department of Corrections and Rehabilitation to begin serving his sentence.

Describes incident in which 6’3”, 320-pound Romaine Alexander Morgan overpowers three officers to grab his AR-style firearm

By Ted Asregadoo, PIO, Contra Costa County District Attorney’s Office

Martinez, California – A report by the Contra Costa District Attorney’s Office on the officer-involved shooting death of Romaine Alexender Morgan in Brentwood on Dec. 24, 2025, is now available to the public.

The Contra Costa District Attorney’s Office is one of a handful of counties in the State of California that publishes public reports on law enforcement-involved fatal incidents. “Being transparent with the public is a cornerstone of my administration,” said District Attorney Diana Becton. “Since 2018, our office has made these reports available to the public, in the hope that transparency brings understanding. It is important for the public to know the significant investigative effort involved in reviewing these incidents, and how our office carefully analyzes the facts through a legal lens when reaching a charging decision.”

As the report details, the incident involving Romaine Morgan of Stockton, begins around 10:54 pm on December 24th, 2025. That’s when Brentwood Police Officer Tanner Kephart notices Morgan’s vehicle in front of him traveling well below the 45-mph speed limit on Deer Valley Road weaving “back and forth…and swerve erratically to the right.” Officer Kephart initiates “a traffic stop under the suspicion of driving under the influence” on Balfour Road. Shortly after, officers Chelsea Valadez and Kimberly Beltran arrive at the traffic stop to assist him.

Morgan was detained, and while searching his vehicle, “Officer Beltran removed a jacket from the front passenger floorboard and located an AR-style firearm”—later determined to be unserialized.

The discovery of the firearm leads to Kephart ordering Morgan to place his hands behind his back, but instead Morgan pushes Valadez, and flees east on Balfour Road, only to stop, change directions, and run back toward the driver’s side of his vehicle to the loaded firearm. A scuffle ensues with officers attempting to grab him. Morgan continues punching and pushing the officers out of the way. Valadez deploys a taser at Morgan, who was 6’3”, 320-pounds, but it is ineffective.

Reaching his vehicle, Morgan finds his firearm, grabs it by the pistol grip, turns towards the officers, and lifts the barrel of the firearm toward them. “All three officers immediately…back away from Morgan.” Kephart retreats next to his patrol car, draws his firearm, and fires “10 times, in rapid succession” at Morgan.

Despite the administration of life-saving measures by officers and medical personnel, Morgan succumbs to his injuries and is pronounced dead by paramedics at the scene. (See related articles here and here)

Shortly after the incident, the Contra Costa District Attorney’s Office launches an independent investigation, as required under county protocol, to determine whether anyone involved may be criminally liable.

After a thorough investigation into the officer-involved shooting of Romaine Alexander Morgan, and in applying the law and the California District Attorney’s Uniform Crime Charging Standards to the present case, the District Attorney’s Office concluded: “Officers Kephart, Valadez, and Beltran acted in lawful self-defense/defense of others, and their use of force was reasonable under the circumstances. As such, no further action will be taken in this case.”

The 32-page report has been sent to the Brentwood Police Department and the California Department of Justice and is available to the public on the Contra Costa District Attorney’s website.

Hayward man convicted of attempted murder in Oakley shooting, faces extradition for 2024 New Zealand murder

By Leave a Comment

Fourth arrest since 2018; also arrested by U.S. Marshalls, alleged to be hit man for organized crime 

By Ted Asregadoo, PIO, Contra Costa District Attorney’s Office

Martinez, California – On May 18, 2026, a Contra Costa County jury convicted a Hayward man of attempted murder with premeditation, shooting at an occupied vehicle, reckless evasion, and being a felon in possession of a firearm — along with firearm enhancements for personally using a firearm.

The convicted man, 26-year-old Tanginoa Pahulu Tangi, (born 12/31/1999) attacked a victim in Oakley on August 27, 2025. Evidence at trial showed that Tangi drove from Alameda County to Oakley and waited approximately three hours outside the victim’s home. When the victim arrived, Tangi approached the vehicle and fired 17 shots at close range. The victim survived. Tangi then fled the scene and disposed of the firearm. Minutes later, a Contra Costa County Sheriff’s deputy attempted to pull Tangi over, but Tangi refused to yield, leading officers on an 11-mile high-speed chase before law enforcement apprehended him.

According to Oakley Police, after Tangi’s arrest, Oakley Detectives Dombrouski, Gill and Pistello worked tirelessly to determine the motive and the actions of Tangi leading up to the shooting. Through collaborative investigative efforts with other law enforcement agencies, Oakley detectives were able to backtrack Tangi’s movements from Oakley to Alameda County. Detectives also determined Tangi waited for the victim to show up at his girlfriend’s house on Trenton Street for more than three hours before the shooting occurred.

The Antioch Police Department assisted by setting up spike strips on Deer Valley near Prewett Ranch Drive. The suspect vehicle became disabled by the spikes and the driver was taken into custody. (See original Oakley PD press release)

The District Attorney’s Community Violence Reduction Unit prosecuted the case. District Attorney Diana Becton said, “This conviction reflects the outstanding work of our entire team, and we are grateful to everyone who helped bring justice for the victim in this case.”

Oakley Police Chief Paul Beard said “This was a very violent act that represented a significant threat to not only the victim, but also to all of the nearby neighbors on Trenton Street on that very early morning. Throughout this case, our Detectives and Special Service Team Officers worked very hard and we received assistance from the Contra Costa County Sheriff’s Office, Antioch Police Department, and the California Highway Patrol. It is very clear to me that Mr. Tangi is a dangerous person and I am grateful the Contra Costa County District Attorney’s Office tried the case in the way they did. This case is indicative that you never know who is coming into your neighborhood at night, so families should take precautions for themselves and their personal security. This event is also evidence that the presence of strong police forces that work together cohesively can make all the difference; I am proud to be part of the cohesive nature of the law enforcement agencies in East Contra Costa County. I hope the victim in this case continues to heal from his injuries.”

Tangi’s violent conduct extends beyond the United States. Authorities in New Zealand currently want him for the murder of a courier in Auckland.

His sentencing hearing for the Contra Costa County offenses is scheduled for June 29, 2026, at 8:30 a.m. in Department 4 of the Richard E. Arnason Justice Center in Pittsburg.

Case No. 04-25-01632 | The People of the State of California v. Tanginoa Pahulu Tangi

According to localcrimenews.com, Tangi is Asian Pacific Islander and has been previously arrested three other times in 2018 and 2020 for burglary, robbery and use of a deadly and/or dangerous weapon.

Arrested by U.S. Marshalls for New Zealand Murder as Hit Man

According to the Contra Costa Sheriff’s Office, he is six-foot, one-inches tall, 225 pounds, and is being held in the Martinez Detention Facility. Tangi was also arrested on Sept. 5, 2025, by U.S. Marshalls for the New Zealand case.

According to the Kaniva Tonga news source in New Zealand, Tonga Independent and Helm.news, Tangi is accused of being sent from California to New Zealand in 2024 to commit murder, leading to the death of an Auckland courier and he now, faces extradition. “Police say a United States national (Tangi) alleged to have acted as a contracted ‘hitman’ in the killing of Auckland courier driver Tuipulotu Kokohu Vi.”

“New Zealand Police alleged the 26‑year‑old flew into the country in August 2024, carried out the fatal shooting, and then fled back to the US before investigators were able to identify him. New Zealand police say he is also the subject of an extradition request relating to the Auckland killing.”

Tangi “is accused of traveling from California to New Zealand in 2024 at the direction of a U.S.-based organized crime group to carry out a murder. He is charged in New Zealand with the fatal shooting of 59-year-old Auckland courier Tuipulotu Vi, who was found dead in his van; police believe Vi was not the intended target. After the incident, Tangi returned to the U.S., where he was arrested in August 2025 following a separate shooting attempt. Extradition to New Zealand is pending, with three others now charged in connection with the case. The investigation remains active, and suppression orders have been lifted, allowing further details to be reported.”
