A California neurosurgeon facing trial for alleged child sex crimes was reportedly found dead in his jail cell Sunday morning in a suspected suicide.

James Kohut, 59, was found alone in his cell at the Santa Cruz County Jail when breakfast service began at 5:45 a.m., the sheriff’s office told the Santa Cruz Sentinel.

Kohut didn’t have a cellmate and was held in the jail’s protective housing unit, the paper reported. The former brain surgeon had been placed on suicide watch earlier in his incarceration but was not on it at the time of his death, the sheriff’s office said.

A forensic pathologist’s preliminary investigation suggests Kohut killed himself, KSBW-TV reported. An autopsy was scheduled for this week as authorities continue to investigate the manner of his death.
