TMZ Sports reported Knight could've been sentenced for more than 50 years if he had been found guilty of all charges. The Maricopa County Medical Examiner was working to determine the cause of death.
Phoenix Police responded after Knight was found by Phoenix Fire and pronounced dead.
In more sad news, Tyler Honeycutt, another UCLA basketball player, was found dead on Saturday, July 7. Knight starts off the roughly 6-minute clip by saying, "This is probably my last message on Earth".
Authorities say there has been no sign of foul play in Knight's death. "I lied, I cheated and I stole", he said.
Mental illness is a bad disease and should be treated very seriously.
The 39-year-old Knight was a guard/forward at UCLA from 1998-2002, averaging 14.1 points and 3.5 rebounds per game as a senior.
At the end of the video, Knight spoke dearly of his brother, Eric, whom he seemed to express remorse for treating badly. He also noted that he "felt like I didn't belong here on earth". He urged people with problems to get help. "Either I'll be in heaven or will be in hell or I'll be in limbo, I don't know, but I'll take that chance".
The Bruins basketball program tweeted its condolences on Tuesday: "Our hearts are heavy". Knight played professionally overseas including stints in France and Japan and worked as a basketball skills coach. "We ask that the Bruin family keep Billy's loved ones in their thoughts during this hard time". Following his playing career, he would become a basketball operations assistant for the G-League's Northern Arizona Suns, an affiliate of the Phoenix Suns, from 2016-2017.
