Darren Rainey spent two hours locked in a shower inmates at the Dade Correctional Institute said prison guards left set to scalding hot before dying of the injuries caused by the water. Rainey’s skin was peeling off when he was removed from the shower. Inmates say he was screaming to be let out before he died, and that guards regularly used extremely hot and cold showers to punish mentally ill patients. Nearly five years later, in a report released Friday, the state’s attorney has ruled that there was no criminal conduct by the guards.

In her ruling, Katherine Fernandez Rundle said, according to the Miami Herald, that John Fan Fan, a sergeant, and the officers involved in getting Rainey into the shower, Ronald Clarke, Cornelius Thompson, and Edwina Williams, didn’t act with premeditation, malice, recklessness, ill-will, hatred or evil intent. The officers involved were eventually promoted after the incident.

The state attorney claimed testimony from inmates was inconsistent with testimony from prison staff as well as physical evidence, and that she could not find evidence Rainey was burned to death. His family says they were pressured to cremate his body, the fact that Rainey’s skin fell off on contact after his death is undisputed, and the nurse who tried to take his temperature after he died said it was too high to register on the thermometer. A prison officer tested the shower a couple of days after Rainey’s death, finding it went as high as 160 degrees, but no investigators checked the shower the day of Rainey’s death.
