Convicted cop killer Michael Alston's appearance before the New York state parole board will be closely watched by law enforcement officers at the hearing on Friday.
Alston, a gang drug enforcer known on the street as "Sugar Bear," killed off-duty NYPD Sgt. Keith Levine in 1991, during an ATM robbery. Levine was heading home at 2 a.m. on Dec. 28, 1991, when he noticed the robbery in progress.
