Orleans Parish Coroner Jeffrey Rouse has made the preliminary determination that the inmate who died at Interim LSU Hospital on Saturday after being transported from Orleans Parish Prison passed away from natural causes.

Allen was placed on what the Orleans Parish Sheriff’s Office called “the appropriate medical protocol” for opiate detoxification after he was brought into the prison on Thursday. He was found unresponsive on Saturday and taken to the hospital, where he was pronounced dead at 7:42 p.m.

Rouse said that initial autopsy results showed that Allen had died of “a cardiac-related cause of death.” He found no signs of trauma on Allen’s body.
