UPDATE 7/10 2:09pm
The warden at the Dade correctional institution is suspended.
An inmate died at the prison in 2012 after he was left alone locked in a tiny shower under scalding hot water.
Jerry Commings will be on paid administrative leave until the investigation is finished.
The suspension is the first disciplinary action taken in this case and comes after news reports found that Darren Rainey's death was never properly investigated.
Civil rights groups have called for a federal investigation .
MIAMI (AP) - The head of Florida's prison system says he's traveling to Dade Correctional Institution for a full assessment on the death of a mentally ill prisoner left in a shower so hot his skin separated from his body.
Department of Corrections Secretary Mike Crews said Wednesday that he will meet with Miami-Dade police officials to offer assistance on the investigation.
The announcement comes several weeks after civil rights groups sent a letter to the U.S. Department of Justice asking for a federal investigation.
The groups say Darren Rainey was locked in a closet-size shower stall at the Dade Correctional Institution in June 2012 as a form of punishment. He was left unattended for two hours with scalding hot water that later measured as high as 180 degrees. He was found dead.
