To discuss Sheriff’s Office response to ICE civil immigration enforcement activities

By Kristi Jourdan, PIO, Contra Costa County & Jimmy Lee, PIO, Contra Costa County Sheriff’s Office

(Martinez, CA) – The Contra Costa County TRUTH Act Community Forum to discuss civil immigration enforcement activities is scheduled for 10 a.m., Tuesday, Aug. 25, during the regular Board of Supervisors meeting.

The forum discussion will present Contra Costa Sheriff’s Office 2025 data on responses to ICE Requests for Notification for serious and/or violent offenders currently in custody, in compliance with state law. The annual forum has been held since 2017 in accordance with California’s Transparent Review of Unjust Transfers and Holds (TRUTH) Act, which requires local jurisdictions to hold a public forum and report on certain interactions with federal immigration authorities.

Jourdan and Lee were asked why they are referred to as, “civil immigration enforcement activities” when the forum will discuss “responses to ICE Requests for Notification for serious and/or violent offenders currently in custody” and shouldn’t they be considered criminal immigration enforcement activities.

Jourdan responded, “we use ‘civil immigration enforcement’ in alignment with the definition of ‘ICE access’ under section 7283(d).”

“The annual TRUTH Act forum reflects our commitment to strengthening trust through open dialogue,” said Board Chair Diane Burgis, District 3 Supervisor. “By creating a space for the public to ask questions, hear information directly from local law enforcement, and share their concerns, we ensure these conversations are grounded in transparency that keeps our community informed and engaged.”

According to the California Department of Justice Office of the Attorney General, “Effective January 1, 2017, California’s Transparent Review of Unjust Transfers and Holds (TRUTH) Act ensures that local law enforcement agencies provide individuals in their custody with basic due process and information about their rights should federal immigration authorities seek to make contact with them. Specifically, the law requires:

  • Before subjecting an individual in its custody to an interview by Immigration and Customs Enforcement (ICE) a local law enforcement entity shall provide the individual with a written consent form, in a language that is understandable to the individual, that explains all of the following:
    • The purpose of the interview;
    • That the interview is voluntary; and
    • That he or she may decline the interview or may choose to be interviewed only with his or her attorney present.
  • Upon receiving any detainer, notification, or transfer request, the local law enforcement agency shall:
    • Provide a copy of the request to the individual; and
    • Inform the individual whether the law enforcement agency intends to comply with the request.
  • If a local law enforcement agency chooses to provide ICE with notification that an individual will be released from custody on a certain date, the local law enforcement agency must promptly provide the same notification in writing to the individual and to his or her attorney or other person designated by the individual being held.
  • All records relating to ICE access provided by local law enforcement agencies, including all communication with ICE, are public records for purposes of the California Public Records Act, but to protect the privacy of individuals, personal identifying information may be redacted prior to public disclosure.”

Ways to Participate:

  • Attend the forum in person on August 25 at 1025 Escobar St. in Martinez
  • Watch live at www.contracosta.ca.gov or on CCTV:
    • AT&T U-verse Channel 99, Comcast Channel 27, or WAVE Channel 32.
  • Provide comments or questions in person, by phone, or Zoom during the meeting, or provide public comment in advance by emailing it to TRUTHAct@cob.cccounty.us or mailing it to the Clerk of the Board, 1025 Escobar St., 1st Floor, Martinez, CA 94553.
  • The meeting will include real-time closed captioning and live translation through Wordly.

Phone and Zoom participation details will be included in the Aug. 25 agenda, posted at least 96 hours before the meeting.

Safety tips for Boating Season

By Leave a Comment

By Jimmy Lee, Director of Public Affairs, Contra Costa County Office of the Sheriff

Memorial Day weekend marks the traditional start of boating season on the Delta. The Contra Costa County Office of the Sheriff is urging all boaters to stay safe while enjoying the water.

“Many boating accidents can be avoided by planning ahead,” said Contra Costa Sheriff David Livingston. “80% of boating fatalities could have been prevented by wearing a life jacket. Fol-lowing the law and these tips could help you stay safe on the water.”

California Boater Card Required – Anyone who operates a motorized vessel must carry a California Boater Card. Learn more at californiaboatercard.com.

Engine Cut-off Switch – Last year, California law required the use of an engine cut-off switch—also known as a kill switch or lanyard—on ves-sels under 26 feet. This safety device must be worn by the operator when at the helm and operating above 5 mph or dis-placement speeds. This law is designed to prevent runaway boat incidents in the event the operator is thrown from the helm, adding another layer of safety to California waterways.

Life Jackets Save Lives – All vessels, including stand-up paddleboards (SUPs), must carry a U.S. Coast Guard-approved life jacket for each person on board. Life jackets must be the correct size for the intended wearer and children under 13 must wear a life jacket at all times aboard a vessel, unless in a fully enclosed cabin. Everyone is strongly encouraged to wear a life jacket at all times on the water.

Boating Under the Influence (B.U.I.) – Operating a vessel under the influence of drugs or alcohol is illegal and dangerous. Boaters arrested for B.U.I. face similar consequences to D.U.I. drivers, including fines, license suspension, and possible jail.

Safe Navigation Practices – Always operate at safe speeds, especially in narrow channels or areas with limited visibility. Stay to the right side of the waterway. In crossing situations, the vessel to the right has the right of way.

Ski Flags and Observers – While engaged in towing activities, an observer who holds the ski flag, at the minimum age of 12 years old, must display the ski flag when required: a downed skier in the water, a skier in the water preparing to ski, a line is in the water extended from the vessel, and a ski or similar equipment is in the water in the vicinity of the vessel.

Blue Light Law – Boaters must slow to a no-wake speed when approaching/being approached by any law enforcement or emergency vessel displaying an illuminated blue light, whether the patrol vessel is moving or stationary.

Emergency Preparedness – Carry an emergency kit that includes a flashlight, warm clothing, a cell phone, VHF radio, and navigational charts. Before heading out, file a float plan. Learn how to create a float plan at: https://uscgboating.org/recreational-boaters/floating-plan.php

Carbon Monoxide Awareness – Be cautious of carbon monoxide buildup, especially when sitting on the swim platform or near the boat’s transom while the engine is running.

Youth Operation Rules – Children ages 12–15 may operate boats with motors over 15 horse-power or sailboats over 30 feet only if directly supervised by an adult (18+) who holds a California Boater Card.

Throwables Required – Boats 16 feet and longer must carry a U.S. Coast Guard-approved throwable flotation device, such as a life ring or square cushion, which must be easily accessible.

Additional Resources – The ABC’s of Boating safety handbook is available at most boating retailers. Visit dbw.ca.gov for more boating laws, safety tips, and California Boater Card information. For questions or non-emergency assistance, contact the Marine Services Unit at (925) 427-8507.

In emergencies, Dial 911 or call Contra Costa Sheriff’s Office Dispatch at (925) 646-2441.

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.”
