LAPD investigates officer's death during dive training in Huntington Beach

The Los Angeles Police Department is investigating the death of an officer during a dive training exercise in Huntington Beach, Orange County, last week, CBS News Los Angeles reported. The officer, Thomas Denton, was assigned to the LAPD's Metropolitan Division, which includes specialized units such as SWAT, K-9, and the Underwater Dive Unit.

According to the Los Angeles Times, Denton died while testing a closed-circuit rebreather device at a private residence pool. This device allows divers to stay underwater longer by filtering exhaled breath to remove carbon dioxide, preventing air bubbles from surfacing. The technology is typically used by the SWAT team's tactical diver unit for clandestine operations.

The LAPD noted that its divers have historically conducted numerous recovery operations, underwater crime scene investigations, and homeland security sweeps. However, Denton's unit, the Underwater Dive Unit, usually focuses on searches for evidence or missing persons.

Authorities, including the California Division of Occupational Safety and Health (CAL OSHA), are conducting investigations into the circumstances of Denton's death. There is particular attention on whether safety protocols were followed during the training at a private residence rather than a department facility.

Experts have noted potential dangers of using closed-circuit rebreathers, especially for untrained divers, due to risks like oxygen depletion or hypoxia. The LAPD has stated it will share findings from its comprehensive investigation when appropriate.
