Former NFL Star Lawrence Philips was found dead in his California prison cell under mysterious circumstances.
Officials suspected that Philips, 40, took his own own life.
In the 1990s, he was a star player at the University of Nebraska, making him a sought-after rookie in the NFL.
Phillips played for the St Louis Rams, Miami Dolphins and San Francisco 49ers until 1999, but his career was marred with disciplinary problems on and off the field.

Eventually, he was sent to prison after being convicted of assault for driving his car into a group of teenagers.
In another case, he was convicted of assaulting a former girlfriend.
Phillips, who was serving a term of more than 30 years, had been placed under solitary confinement after he was accused of killing his former cellmate.
On Tuesday, a judge found that there was enough evidence to try Phillips on the death of Damion Soward, 37.
“He was an intelligent person and had some good qualities,” Tom Osborne, his coach at Nebraska said.
“Yet he had some anger issues and couldn’t overcome the demons in his life.”
