An autopsy found that former University of Nebraska and NFL running back Lawrence Phillips hanged himself with a bed sheet in January at the Kern Valley State Prison in California.
Josh Peter of USA Today provided the details of the coroner's report Wednesday, which stated correctional officers found him unresponsive in his cell with a note reading "Do Not Resuscitate" taped to his chest.
Phillips was transferred to a nearby hospital before being pronounced dead. The coroner's report ruled his death a suicide by asphyxia due to hanging. It also stated there were no illegal drugs or psychiatric medication in his body at the time of his death, according to USA Today.
