*Officials are investigating the death of former NFL star Lawrence Phillips, who was found dead in his prison cell.

According to TMZ, Philips’ body was discovered at 12:05 a.m. Wednesday when staff conducted a routine security check and noticed Lawrence was unresponsive.

Officials say he was transported to an outside hospital where he was pronounced dead at 1:27 a.m.

Phillips had been in solitary confinement since April — after he was suspected of killing his cellmate 37-year-old Damion Soward. He was recently charged with murder.

The 40-year-old — who played for the Rams, Dolphins and 49ers — was initially locked up in Kern Valley State Prison in California on a 31-year sentence for a number of convictions, including spousal abuse.

He was a running back at the University of Nebraska in the 1990s before playing in the NFL in a career cut short by off-field incidents and legal trouble.
