The Medical Examiner’s Office will conduct an autopsy to determine how a 44-year-old Halawa Correctional Facility inmate, who was serving time for robbery, died in his cell.

Corrections officials said preliminary reports indicate that inmate Reginald Saia  committed suicide.

Prison guards found Saia unresponsive in his cell while doing their normal headcount at 4 a.m. Thursday.

Prison staff immediately began CPR on him.  Paramedics arrived at 4:27 a.m. and continued CPR while taking him to Pali Momi Medical Center.  He was pronounced dead at Pali Momi at 5:09 a.m.  

Saia was serving time for second-degree robbery.

The incident is under investigation.

Saia was the fourth prison suicide since April.
