Walker then stopped breathing and CPR was performed until paramedics arrived.
Efforts to revive him were unsuccessful and Walker was pronounced dead.
An autopsy was performed on March 2 and preliminary results show massive internal bleeding due to a perforated ulcer that ruptured an artery in the stomach lining.
