how did dennis wilson die

Dennis Wilson, drummer and co-founder of The Beach Boys, died by accidental drowning on December 28, 1983, at age 39.

What happened that day?

Dennis spent the day drinking aboard a friend’s boat in Marina del Rey, California, after a long struggle with alcohol and drug addiction. In the afternoon he repeatedly dived into the marina to retrieve items that had been thrown overboard from his old boat years earlier, and he failed to resurface from one of those dives.

Official cause of death

Authorities ruled his death an accidental drowning. Later commentary from a forensic pathologist suggested he likely experienced a shallow-water blackout brought on by breath-holding, cold water, and heavy intoxication.

Context and struggles before his death

In the months leading up to his death, Dennis had been in and out of treatment programs trying to address severe alcoholism and cocaine abuse. Just days before he died, he had checked into a hospital program but left and resumed heavy drinking, telling friends he planned to return to detox, a plan he never got to carry out.

TL;DR: Dennis Wilson died at 39 after a day of heavy drinking and repeated dives in Marina del Rey; his death was ruled an accidental drowning, likely worsened by intoxication and possible shallow-water blackout.
