Cleveland kidnapper Ariel Castro may have died from auto-erotic asphyxiation, not suicide

Officials suggest he wasn't trying to kill himself

COLUMBUS, Ohio - Officials suggest it is possible Cleveland kidnapper Ariel Castro may have died of auto-erotic asphyxiation, not suicide.

Castro's pants and underwear were pulled down to his ankles when he was found, according to the report released Thursday.  It also says Castro did not leave a suicide note and "multiple levels of assessment" did not find tendency toward suicide.

The state forwarded those facts to police to consider the possibility of auto-erotic asphyxiation, whereby individuals achieve sexual satisfaction by briefly choking themselves into unconsciousness.

Ohio officials say two prison guards falsified logs documenting their observation of Castro in the hours before he killed himself.

A report from the Ohio Department of Rehabilitation and Correction says video indicates no checks were done on Castro at least eight times the afternoon and evening before he died.

The report says checks were done properly twice before Castro hanged himself on Sept. 3 at a prison reception center south of Columbus.

The report also says an ambulance contracted to provide medical assistance at the prison was significantly late in arriving, but the delay didn't affect the outcome.

The report also says prison staff failed to make sure Castro watched a suicide prevention video when he first arrived in August.
