CLEVELAND, Ohio – A state review of condemned killer Billy Slagle's prison suicide shows corrections officers skipped security rounds and falsified logs the morning Slagle took his own life.

The Ohio Department of Rehabilitation and Correction on Monday released its review, which concluded supervisors should verify rounds using surveillance footage and officers responsible for conducting checks on death row inmates should receive special training.

Slagle was found Aug. 4 hanging in his Chillicothe Correctional Institution cell. He was to be executed Aug. 7 for the 1987 murder of his neighbor Mari Anne Pope, who he repeatedly stabbed with a pair of scissors while two children she was babysitting watched.

According to the review, DRC officer John McCollister, 30, falsely indicated on the prison's electronic log that Slagle's death row cell was checked consistently in 30-minute intervals, as required by the DRC, during the overnight shift.

The log shows rounds were conducted in the required intervals beginning at 10 p.m. Aug. 3 – when the shift began -- until about 5 a.m. Aug. 4, when Slagle's body was found hanging in the cell.

The DRC review states that corrections officer Clay Putnam, 19, conducted the shift's first check on Slagle's cell at 11:20 p.m. and that he completed rounds once every hour beginning just after 2 a.m.

McCollister and Putnam were placed on paid, administrative leave while the DRC conducted its review. A DRC spokeswoman said the department has not determined if the officers will face discipline.

Earlier this month, the DRC placed two more officers on administrative leave following the prison suicide of Ariel Castro, who tortured three Cleveland women in his home for nearly a decade.

Placing involved officers on administrative leave following an inmate suicide is department policy, according to the DRC.

Castro was found Sept. 3 hanging in his cell at the Corrections Reception Center in Orient, Ohio.

Castro kidnapped and raped Michelle Knight, Gina DeJesus and Amanda Berry in his Seymour Avenue home. He was sentenced to life in prison plus 1,000 years.

Castro is the seventh Ohio inmate to take his own life this year.

Convicted rapist James Blackburn last week became the eighth.

Blackburn was found Sept. 10 hanging in his Lebanon Correctional Institution Cell, according to the DRC.
