The Delaware Division of Forensic Science had determined the cause of death of the correctional officer killed in the hostage standoff at the state prison near Smyrna.

In a press release Friday at 7:52 p.m., Delaware State Police Master Cpl. Gary Fournier said the Division of Forensic Science has completed the autopsy of James T. Vaughn Correctional Center officer Steven R. Floyd.

The cause of death has been determined to be "homicide by trauma," Fournier said.

No further information regarding the autopsy will be released to protect the integrity of the active and on-going investigation, Fournier said.

At about 10 p.m. on Friday, State Police cleared the crime scene at the Vaughn Correctional Center and turned Building "C" back over to the Delaware Department of Correction.

Because of the circumstances surrounding this tragic incident, this investigation is expected to be lengthy, Fournier said. Detectives are continuing to conduct interviews as well as collect and examine countless pieces of physical and video evidence.

FLOYD POSTHUMOUSLY PROMOTED AND HONORED

On Friday afternoon at the Department of Correction training academy graduation ceremony in Dover, Floyd was posthumously promoted from sergeant to lieutenant by Correction Commissioner Perry Phelps, who also presented the Department of Correction Medal of Valor to Floyd's son.
