A Kansas man accused of raping and attempting to kill a woman was found dead in his jail cell Sunday morning.

Detention staff found 59-year-old Gary McCormick unresponsive in his cell at 4:51 a.m. during a routine check.

Staff members and firefighters tried to revive him, but were unsuccessful.

McCormick had been in custody since July of 2015 on charges including second-degree murder, pre-meditated first-degree murder and rape.

Johnson County was holding him on a million dollar bond. McCormick was scheduled to appear in court on May 15.
