King has been referred to as an avid swimmer by news sources and friends. Neighbor Dee Schnepf says it was not uncommon for him to be swimming late at night or early in the morning, and adds that he liked swimming in the dark.
Johnnie Kelly, a close friend and former bodyguard of King, claims that he was a great swimmer, loved swimming, and it was common for him to swim in his pool while under the influence of alcohol.
Not to mention, King had been struggling with alcohol abuse throughout his life. He was even featured in Celebrity Rehab with Dr. Drew.
Overall, King was considered to be a very capable swimmer that swam regularly, according to friends and neighbors.
Given, it's likely that he was intoxicated. However; friends claim that he commonly swam with a few drinks in him, and he's battled alcohol addiction for years. So why all of a sudden would being intoxicated make him completely unable to stay afloat to the point where drowning would occur?
It's not like there was an apparent head wound knocking him unconscious, or any clear signs of suicide or drug use.
