Sgt. David Mascarenas is the Dive Supervisor for the Los Angeles Police Department. He’s been diving his whole life, and prides himself on never refusing a dive, no matter how treacherous.

We checked in with Sgt. David Mascarenas again in 2020, and he was able to tell us more about the investigation. Listen to the update here.
