Weidhofer Cold Case

By East Bay Regional Park District Police Department

The East Bay Regional Park District Police Department announced Wednesday, February 19, 2025, that DNA evidence has conclusively identified the murderer in a 35-year-old case that took place in Charles Lee Tilden Regional Park in Berkeley, CA.

Evidence collected from Jon Lipari, who died by suicide in Oregon in November 2024, was linked to the victim Maria Weidhofer, a Berkeley resident. She was an avid jogger and park user of Tilden Regional Park.

On Nov. 16, 1990, Weidhofer was found deceased on a trail near Inspiration Point in Tilden Regional Park. Weidhofer was found with rope around her neck and with physical signs of a struggle after she had been reported missing the night before.

An autopsy, performed at the time of the crime, found that Weidhofer’s cause of death was asphyxia by ligature strangulation and found a multitude of minor abrasions and contusions upon her person. A lengthy investigation was conducted in 1990-1991 by the East Bay Regional Park District Police Department. A suspect was not identified from this initial investigation.

In 1997, biological evidence found on Weidhofer from the suspect was sent to the Contra Costa Crime Lab for analysis. That evidence was later submitted to the Combined DNA Index System (CODIS). Among the evidence collected, during the initial investigation, was semen from which a DNA profile was generated.

In 2020, the East Bay Regional Park District Police Investigations Unit began working with the Federal Bureau of Investigation (FBI) on this case. This collaboration included the use of advanced DNA techniques. Through this investigation, Lipari was determined to be a potential suspect and became the primary suspect in 2024.

Once Lipari was identified as a potential suspect, hundreds of hours of further investigation were conducted in collaboration with the FBI, Contra Costa County District Attorney’s Office, and the Curry County Sheriff’s Office. The investigation also determined that Lipari was living in Gold Beach, OR.

In early November 2024, Lipari was found deceased in his residence by local law enforcement from a self-inflicted gunshot wound. DNA from the scene was retrieved by the Curry County Sheriff’s Office and a direct comparison was done by the Contra Costa County Crime Lab. The comparison determined the DNA profiles generated from the evidence collected at the original scene and the DNA from Lipari were a match.

There is no indication from the investigation, Weidhofer’s family, or Lipari’s family, that there was any previous contact between the victim and suspect.

“We hope that today’s development brings some measure of closure to the family, who have shown tremendous strength throughout this difficult time” said Roberto Filice, Chief of the East Bay Regional Park District Police Department. “This breakthrough comes after years of relentless investigation, and I want to personally thank our dedicated staff for their perseverance and firm commitment to seeking justice. Their determination to never give up ultimately led to solving this case, and we are proud to serve a community that stands together in the face of tragedy.”

Special thanks to the FBI, the Contra Costa County District Attorney’s Office, the Contra Costa County Sheriff’s Forensic Services Division, and the Curry County Sheriff’s Office for their collaboration, expertise, and dogged determination in solving this 35-year-old case.

In posts on X (formerly Twitter) on Wednesday Contra Costa Sheriff David Livingston wrote, “Contra Costa Sheriff’s Crime Lab played key role in the case. In 1997, lab analyzed biological evidence, generated a DNA profile, and uploaded it to CODIS database. Recently, crime lab received a reference sample from Lipari and was able to confirm that he was the suspect.

“The Contra Costa Sheriff’s Office Forensic Services Division Crime Lab is proud to assist our law enforcement partners in their investigations and help bring answers and closure to victim’s families,” he added.

During Wednesday’s press conference Contra Costa Deputy DA Satish Jallepalli said, “Thank you, (EBRPD Police) Chief Filice for having us here, today to remember Maria Weidhofer and to be able to speak on her behalf. Pursuit of justice is a marathon not a sprint. We’re all standing here today because of our shared commitment to justice. It’s been 35 years since Maria was murdered on November 15, 1990. Since that day, her death and circumstances touched everyone, her family, the community and members of law enforcement. Everyone who worked on this case for 30-plus years was dedicated to solving this crime. They did so with shared determination that Maria’s death would not remain unsolved.”

“The partnership of this case between East Bay Regional Parks Police, the FBI, the District Attorney’s Cold Case Unit and the Contra Costa County Crime Lab was a reflection of that determination, using the latest technology and investigative techniques to obtain answers that could not have been obtained decades or even years ago,” he continued. “The pursuit of justice requires endurance, resilience and the willingness to go the distance even when the path ahead is long and uncertain,” Jallepalli stated. “While solving this case will never heal the wounds of Maria’s family caused by her murder we, from the District Attorney’s Office, are grateful to have been a part of that effort to bring these long-awaited answers to the community and more importantly, to her family.”

22-year-old arrested on four charges including continuous sexual abuse of a child under 14
Charged by Contra Cost DA with 16 felony counts
Held on $7 million bail

By Lt. Donald Patchin, PIO, Richmond Police Department

On Tuesday, January 28, 2025, at around 3:00 PM, a Richmond PD sergeant was flagged down by someone who wanted to report a possible sexual assault. The person provided information about a juvenile who was possibly the victim of a sexual assault. Officers immediately launched an investigation. They determined the possible victim was currently with the alleged suspect. They also determined the suspect and victim were alone and unsupervised.

Officers immediately responded to the victim’s location. Upon knocking on the residence door, a male subject clad in only a bath towel answered. Officers quickly located the victim inside the residence and found out that the suspect was the male who answered the door. Officers learned through the subsequent investigation that the suspect had been in the act of sexually assaulting the juvenile when officers arrived on the scene. Officers knocking on the door forced the suspect to end the sexual assault.

Although we wish we would have arrived in time to prevent the sexual assault, we are glad we arrived in time to prevent the assault from continuing and to rescue this juvenile victim from their assailant.

Special Victims Unit Detectives immediately responded to assume the investigation. Detectives worked with the Contra Costa District Attorney’s Office to ensure the suspect remained in police custody and that charges were filed.

On January 30, 2025, the Contra Costa District Attorney’s Office filed a 16-count felony complaint against the suspect, Marlon Alexander Maravilla Martinez, a 22-year-old resident of Richmond (born May 22, 2002). He remains in custody with a $7,000,000.00 bail. All sixteen counts relate to lewd and sexual acts on a child who is ten years old or younger.

The victim is now safe with her family and receiving the help and resources she needs.

According to localcrimenews.com, Martinez was arrested for 261(A)(1) – rape of a victim incapable of consent, 288.5(A) – continuous sexual abuse of a child under 14, 288(B)(1) – forcible lewd acts upon a child, and 288.7(A) – engaging in sexual intercourse or sodomy with child 10 or more years of age.

According to the Contra Costa County Sheriff’s Office, the five-foot, six-inch, 215-pound Martinez is being held in the West County Detention Facility. His next court appearance is scheduled for Feb. 19, 2025, in Superior Court in Martinez at 1:30 PM.

Brandished what appeared to be a knife but determined later to be a sheath

CA Attorney General investigating

By Lt. Donald Patchin, PIO, Richmond Police Department

On Tuesday, February 4, 2025, at 8:13 p.m., officers from the Richmond Police Department responded to the 2700 block of Maine Avenue in an attempt to locate a wanted subject. The subject was wanted on a probation violation warrant related to domestic violence charges.

Officers located the wanted subject on the Union Pacific Railroad right of way just west of the 300 block of Carlson Blvd. The subject refused to cooperate with officers, and a standoff ensued. During the standoff, the suspect wielded an object that appeared to be a knife. The subject ignored multiple commands to drop the object. Officers spent approximately 32 minutes attempting to de-escalate the situation and reach a peaceful resolution.

Despite our officers’ efforts to defuse the situation and end the standoff peacefully, the suspect charged the officers with the object in his hand while raising it in a threatening manner. At approximately 8:53 p.m., an officer-involved shooting occurred, and the wanted subject sustained fatal injuries.

We later determined the object was not a knife. The black knife sheath in the photo is the object the subject wielded, which investigators recovered at the scene.

The Contra Costa Law Enforcement Involved Fatal Protocol, a set of guidelines and procedures followed in cases of officer-involved fatalities, was invoked, and the Contra Costa District Attorney’s Office responded to investigate.

We are committed to a thorough, transparent investigation.

Under the requirements of AB 1506, we recognized the California Department of Justice (DOJ) treats this as an “unarmed” officer-involved fatal incident, and we immediately notified them. The DOJ dispatched investigators to the scene to investigate.

We are fully cooperating with the DOJ’s independent investigation. We believe it is important to release information in a transparent manner. We intend to release additional information as soon as the investigation allows.

According to a press release issued on Wednesday, Feb. 5, “California Attorney General Rob Bonta announced that the California Department of Justice (DOJ), pursuant to Assembly Bill 1506 (AB 1506), is investigating and will independently review an officer-involved shooting (OIS) that occurred in Richmond, California on Tuesday, February 4, 2025.

Following notification by local authorities, DOJ’s California Police Shooting Investigation Team initiated an investigation in accordance with AB 1506 mandates. Upon completion of the investigation, it will be turned over to DOJ’s Special Prosecutions Section within the Criminal Law Division for independent review.

More information on the California Department of Justice’s role and responsibilities under AB 1506 is available here: https://oag.ca.gov/ois-incidents.”

Following pursuit, collision Brentwood man arrested in Oakley for stolen vehicle

Driver of truck struck by suspect injured, hospitalized

By Oakley Police Department

On January 26, 2025, at 9:16AM Oakley Police Officer G. Ganz located a stolen vehicle driving in the area of Gamay Drive and Empire Avenue. Officer Ganz followed the vehicle as it turned north on Teakwood Drive. As Officer Ganz was following the vehicle, it was learned the person who was suspected of stealing the vehicle was named as Joseph McDonald (44, Brentwood) who was a parolee at large — he has violated the terms of his parole and is wanted back in custody.

Officer Ganz attempted to stop the stolen vehicle, and the driver fled and attempted to make a righthand turn onto eastbound Main Street at a high rate of speed. The driver of the stolen vehicle collided into a Ram 1500 truck, which was travelling westbound on Main Street; both vehicles were immediately disabled. Officers took the driver of the stolen vehicle into custody and determined it was indeed McDonald who had been driving it. The driver of the Ram truck was transported to a local hospital for injuries sustained in the collision. McDonald was also transported to a local hospital and as of this writing, remains hospitalized and in the custody of the Oakley Police Department. Oakley Police staff will be working on getting McDonald formally booked and transferred into the custody of the Sheriff’s Office.

Chief Paul Beard notes, “By mere virtue of Mr. McDonald being a parolee at large, this incident is not the first time he has crossed the threshold of right and wrong. Should McDonald have been out on parole? NO. McDonald was clearly demonstrating a continued pattern of a criminal lifestyle and people were at risk of harm because he was allowed the freedom of prison. I appreciate the efforts of officers like Officer Ganz to hold wrongdoers accountable, and I hope to see charges filed against McDonald that are commensurate to his actions. Collectively, the members of the Oakley Police Department wish for the quick healing of the innocent person who was injured in this incident.
Stay safe Oakley.”

Canadian man sentenced for “sextortion” of Contra Costa County minor

By Leave a Comment

Arrested in 2021 in St. John’s, Newfoundland and Labrador for multiple online child exploitation offences

Multi-agency effort

Sentenced to 2 years in prison, 3 years of supervised release, must register as a sex offender for 10 years

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

A 25-year-old man from Gulf Island, Canada, has been sentenced to prison for sexually extorting a minor in Contra Costa County in 2020, in what is commonly referred to as a “Sextortion” attack.

In the fall of 2019, Nicholas Fahey used a social media application to contact a minor in Contra Costa County and solicited sexually explicit images from the victim. After the victim complied, Fahey sent the victim a series of threats, indicating he would release the images of the victim unless the victim complied with his demands for more photographs.

The investigation was referred to the Contra Costa County Internet Crimes Against Children Task Force (ICAC) and Homeland Security Investigations (HSI). Fahey was identified as the suspect through an investigation of his social media accounts. Ultimately, the Royal Canadian Mounted Police arrested Fahey at his home in Bay Bulls, Canada, located in the province of Newfoundland and Labrador. Fahey was charged on May 21, 2021, in Canada’s version of Superior Court.

On January 23, 2025, Fahey was sentenced to two years in prison and ordered to register as a sex offender for 10 years. Fahey will also serve a term of three years of supervised release.

“This investigation highlights the shared commitment of the ICAC Task Force and HSI to pursue criminals, even those operating beyond U.S. borders,” said District Attorney Diana Becton. “Parents need to understand that individuals who prey on minors online are not restricted by national or state boundaries. Those who use the internet to harm our youth should know that my office will collaborate with law enforcement agencies like the Royal Canadian Mounted Police to seek justice for the victims in our county.”

Sextortion is the most common crime targeting children on social media. According to the FBI, between 2021 and 2023, 12,600 children in the United States were victims of sextortion, resulting in at least 20 suicides.

To report sextortion, contact your local law enforcement agency or file a report with the National Center for Missing and Exploited Children at www.missingkids.org.

Parents are encouraged to talk to their children about the risks associated with smartphone use and social media. If parents, educators, or organizations are interested in presentations on topics like smartphones, social media, or our Vigilant Parents initiative, please contact the District Attorney’s Office at DAOffice@contracostada.org.

According to Corporal Jolene Garland, Media Relations Officer of the Royal Canadian Mounted Police in Newfoundland and Labrador, on April 29, 2021, then-twenty-two-year-old Nicholas Fahey of Gull Island was arrested, following an investigation by the RCMP/RNC Integrated Internet Child Exploitation (IICE) team. He is charged with multiple online child exploitation offences.

The investigation began in early 2020, after police received reports from the US Department of Homeland Security that two American youth had been exploited online by a resident of this province. A local investigation by IICE led to a search warrant that was executed on a Gull Island residence in July of 2020.

Fahey is now charged with the following criminal offences:
• Possession of Child Pornography
• Transmission of Child Pornography
• Making Sexually Explicit Material Available to a Child
• Luring a Child (x2)
• Indecent Act (exposure)
• Extortion (x2)
• Invitation to Sexual Touching

Fahey was released from custody on conditions designed to protect the general public and was scheduled to appear in court on June 16, 2021.

Parents and guardians are encouraged to exercise proper supervision of children while online and to foster regular discussions with their children about online safety.

Following high-speed pursuit of stolen car on Hwy 4 two Antioch men arrested for Dublin robbery

From Oakley to Hercules; with help from Contra Costa Sheriff’s helicopter, CHP

Kalil Houston still in custody on $70,000 bail, Isaiah J. Mitchell bonded out

By Oakley Police Department

On January 10, 2025, at 9:44PM, Oakley Police Officer F. Williams was on patrol on Main Street near Bridgehead Road. Officer Williams saw a gray Honda Accord with a license plate reported as lost or stolen and belonging on a Lexus. It was also made known to Officer Williams the same Honda with the same license plate had been used during a robbery in Dublin. Officer Williams was joined by Officer R. Hernandez and they attempted to stop the Honda, but it fled at a high rate of speed onto westbound Highway 4. Officers Williams and Hernandez initiated a pursuit and the Contra Costa County Office of the Sheriff helicopter (STARR) was in the area within a few minutes.

The suspect continued to flee travelling westbound on Highway 4 reaching very high speeds at times. The pursuit continued for several minutes. Due to the nexus of this vehicle to violent crimes, our officers remained engaged in the pursuit all the way to the City of Hercules. The pursuit ultimately ended in the 1900 block of Railroad Avenue when the driver, identified as Kalil Houston (male, 20, Antioch, born 7/6/04) foot bailed from the vehicle. The passenger, identified as Isaiah J. Mitchell (male, 21, Antioch), remained in the vehicle and was taken into custody immediately. Our officers later caught Houston as he was trying to flee the area and took him into custody as well.

Pursuits by their very nature are dangerous and police agencies diligently assess the need to continue them when they occur. Every decision made in a pursuit weighs the seriousness of the incident versus the public’s safety. When a vehicle is associated with a crime(s) of violence, it becomes more critical to apprehend the violator(s).

Our officers found several stolen license plates and a blank key fob in the possession of Houston and Mitchell and fired shell casings could also be seen inside the vehicle. The Honda was towed to be examined for evidence.

During this pursuit, a Black Ford Mustang started pacing our officers, even at the high speeds that were reached, turned its lights off, and tried to block our officers. The driver of the black Mustang intentionally interfered with our officers and placed our officers in a great degree of danger. Our officers will be doing additional follow-up in an attempt to identify the driver of the Mustang.

Houston and Mitchell were both booked into jail for crimes associated with possession of stolen property, conspiracy and felony evading. The Oakley Police Department will be working with the Dublin Police Department in regards to the robbery that occurred in Dublin.

Chief Beard said of this incident, “It does appear as if Houston and Mitchell were going to continue the destructive and violent behavior their vehicle had already previously been involved in. The action of fleeing at high speeds, the propensity to work in concert with others against police officers, having stolen license plates and spent shell casings is not a good look in any scenario. It is my concern a crime of violence was going to be perpetrated against an innocent person(s) in Oakley. I appreciate and respect Officer Williams and Officer Hernandez for keeping the residents of Oakley safe. Officers from the Contra Costa Sheriff’s Office, the California Highway Patrol and the Hercules Police Department all assisted Officers Williams and Hernandez during this incident, and I extend a personal thank you to each of them.

“The experiences of Officer Williams and Officer Hernandez in this investigation underscores the risks American peace officers face everyday. I am grateful for the service of all peace officers who stand between those who wish to do harm and the rest of society and I am honored to be associated with them.

Stay safe Oakley!”

According to the Contra Costa Sheriff’s Office, the five-foot, 11-inch, 175-pound Houston is being held in the West County Detention Facility on $70,000 bail. His next court appearance is scheduled for Jan. 27 at 8:30 a.m. in Delta Superior Court in Pittsburg.

Also, according to the Contra Costa Sheriff’s Office, Mitchell is Black and as of Jan. 11th, he bonded out of custody. According to localcrimenews.com, Mitchell was arrested on Dec. 22, 2021, by Antioch Police for vandalism – property damage.

Oakley man with priors arrested for stealing shoes from Brentwood store

By Leave a Comment

Charged with felony thanks to passage of Prop. 36

By Brentwood Police Department

On the evening of Sunday, January 12, 2025, around 9 PM, BPD officers responded to a call to a business at the 5500 block of Lone Tree Way regarding a suspect who had stolen shoes from the store.

Upon arrival, officers observed the suspect, later identified as 38-year-old Don Cornell Capers from Oakley (born 4/5/86), attempting to flee in a getaway vehicle. Capers was quickly taken into custody with the assistance of a second BPD officer who had just shown up while Capers was attempting to get into the vehicle.

Capers, who already had a warrant for a probation violation related to his Post Release Community Supervision, also has two prior theft convictions.

As a result of the passing of Proposition 36, which elevates theft offenses for individuals with prior convictions, Capers was place under arrest with “Petty Theft with Priors”, making this incident a felony rather than a misdemeanor. He was also arrested for the warrant, evading police, and other related charges.

According to the Contra Costa Sheriff’s Office, Capers was transferred to another facility and is in custody at the Santa Rita Jail. According to the Alameda County Sheriff’s Office, the five-foot, 11-inch tall, 150-pound suspect is Black and has a court appearance for arraignment in Dept. 702 at the East County Hall of Justice in Dublin on Jan. 22 at 8:30 a.m.
