17000 Block of Crown Circle: LAPD Dive Officer Dies After On-Duty Training in a Backyard Pool

HUNTINGTON BEACH, CALIFORNIA (November 5, 2026): Los Angeles Police Department Officer Thomas Denton died after an on-duty dive training exercise in Huntington Beach late Thursday morning, November 5, 2026, according to the LAPD, as reported by City News Service and the Los Angeles Times. The Times reported on Wednesday that the LAPD and state workplace safety investigators are now examining the circumstances of his death.
Denton, a 20-year LAPD veteran assigned to the elite Metropolitan Division, was a member of the department’s dive unit, according to the Los Angeles Police Protective League and the Times. The exercise began around 11 a.m. at a backyard pool in the 17000 block of Crown Circle, the Times reported. Huntington Beach firefighters were called to the home at about that time, according to the Times. Denton was taken to Orange Coast Medical Center in Fountain Valley, where he was pronounced dead. A law enforcement procession escorted his body to the Orange County coroner’s office in Santa Ana. He is survived by his wife and two children, according to the governor’s office.
Citing two law enforcement sources, the Los Angeles Times reported that Denton may have been testing a closed-circuit rebreather, a device that lets a diver stay underwater longer by recycling exhaled breath. According to the Times, officials are looking into whether safety protocols were followed for training at a private residence rather than a department facility. The California Division of Occupational Safety and Health (Cal/OSHA) is also reviewing the death, the Times reported. The LAPD said in a statement that it is conducting a comprehensive investigation and will share its findings at the appropriate time, and the Orange County Sheriff-Coroner plans a full autopsy.
The LAPD has not said what caused Denton’s death, whether the training had been approved, or who owned and maintained the equipment he was using. The cause of death has not been released. These are early reports, and the facts may change as the LAPD, Cal/OSHA and the coroner complete their work.
Liability for the Huntington Beach Dive Training Death
California generally provides workers’ compensation benefits when a worker is hurt or killed on the job, without regard to fault. California Labor Code § 3600 makes employers liable for compensation for injuries that arise out of and in the course of employment, and Labor Code § 4702 sets out death benefits for a worker’s dependents. Labor Code § 3852 adds that a workers’ compensation claim, expressly including one by a peace officer, does not affect the right to seek damages from a person other than the employer.
- Death benefits: The family of a worker who dies during an on-duty exercise is generally eligible for workers’ compensation death benefits, whether or not anyone was at fault.
- The rebreather: The Times reported that Denton may have been testing a closed-circuit rebreather. If dive equipment fails or lacks adequate warnings, California product liability law generally allows claims against the companies that designed, made or sold it. Investigators have not said whether any equipment malfunctioned.
- Safety rules for the training: Cal/OSHA reviews workplace deaths under the safety orders in Title 8 of the California Code of Regulations. Whether this exercise followed those orders and department protocols is part of the review.
- Other parties: Under Civil Code § 1714, every person is generally responsible for harm caused by a lack of ordinary care. If anyone other than the employer contributed to the death, Labor Code § 3852 generally preserves a separate claim against that party.
These are general principles of California law, not conclusions about this death, which remains under investigation by the LAPD and Cal/OSHA.
Steps to Take After a Workplace Death in Huntington Beach
Deaths on the job remain a serious risk: 5,070 fatal work injuries were recorded in the United States in 2024, according to the U.S. Bureau of Labor Statistics Census of Fatal Occupational Injuries. Families who lose a loved one at work can take these steps:
- Ask about benefits: Ask the employer in writing for information about the workers’ compensation claim and the death benefits available to dependents.
- Contact the coroner: The Orange County Sheriff-Coroner can explain how the family can request the autopsy report and the death certificate once they are available.
- Preserve the equipment: Ask in writing that all dive equipment involved, including any rebreather, be preserved and not repaired, returned or discarded while the investigation continues.
- Keep records: Save training schedules, messages, photos and the names of anyone present, and be careful before giving a recorded statement to any insurance company.
Legal deadlines and notice requirements apply after a crash, injury or death, and they vary with the facts of each case, the location and the parties involved, including any public agency. Contact an attorney as soon as possible to protect your rights.
