Baltimore State's Attorney Gregg Bernstein is to announce this afternoon a decision on whether to prosecute anyone in January's Select Lounge shooting, in which city police officers mistakenly shot and killed a colleague during a fight outside a bar.

A separate review by a panel of law enforcement experts are still conducting a separate review into the case to determine whether proper police procedure was followed and whether any changes need to be made. The department has already curtailed the deployment of plainclothes officers.

Officer William H. Torbit Jr., along with 22-year-old Sean Gamble, were killed in the shooting.

Torbit, 33, was on duty and in plainclothes when he was overcome by a crowd leaving Select Lounge on North Paca Street. Police said he fired during the altercation, killing Gamble. Other officers then opened fire on Torbit, unaware that he was a fellow officer.

Bernstein could announce indictments against the officers, or say that the investigation proved the incident to be a tragic mistake. His news conference is scheduled for 3 p.m.
