HALIFAX - Nova Scotia's Health Department has released details of a review of a Halifax psychiatric facility that released a patient who was later charged in a fatal assault.

The department says the review will focus on patient supervision and public notification when a patient fails to return while out on a pass.

It will also examine community access privileges granted to patients who have been found not criminally responsible.

The provincial government launched the review after Raymond Taavel was beaten to death on a downtown Halifax street last month.

Andre Noel Denny has been charged with second-degree murder in Taavel's death.

Denny was granted a one-hour unescorted leave from the East Coast Forensic Hospital on the night Taavel died but he didn't return to the facility.

The department says Dr. Alexander Simpson, the clinical director at the Centre for Addiction and Mental Health in Toronto, and Dr. Johann Brink, a psychiatry professor at the University of British Columbia, will help lead the review.

The review is expected to finish this summer.
