Rundle's office refused to prosecute four prison guards connected to the death of Darren Rainey, an African-American prisoner who suffered from schizophrenia. In 2012, the prison guards allegedly locked Rainey inside of a running hot shower for nearly two hours, boiling his internal organs, killing him. Another inmate said he heard Rainey yelling and kicking the door and begging to be taken out. Despite the incident having been recorded on video, Rundle concluded that the inmate's claims were not supported by the evidence. Additionally, witnesses reported that Rainey's skin appeared to have been "peeled back;" the autopsy found that those marks were caused by friction. Rundle's report concluded that Rainey's death was an "accident" resulting from his mental condition, a heart condition, and "confinement in the shower."
