In 1982, Grandison was on parole after having served several years in prison for assaulting a DEA agent, carrying a firearm during the commission of a felony and possession of a firearm by a convicted felon, a 1979 conviction that was sustained on appeal in 2003. While going through security at
Baltimore-Washington International Thurgood Marshall Airport on his way to Miami a baggage screener noticed a substantial amount of cash in Grandison's luggage. The
U.S. Marshals service later arrested him on suspicion of violating his parole, and a search of his belongings revealed a key for a room at the Warren House Motel (now a
Howard Johnson's) in
Pikesville, Maryland. A search of the room found a substantial amount of cocaine and heroin, which resulted in Grandison being indicted on federal drug charges. Two key witnesses in the government's case were David Scott Piechowicz and his wife, Cheryl. David Piechowicz was the motel's manager, and he and Cheryl were the only two witnesses who could place Grandison in the room where the drugs were found. Cheryl's sister, Susan Kennedy, was filling in for her at work on the morning of April 28, 1983, when
Vernon Lee Evans, a hitman who had been hired by Grandison, entered the motel lobby and shot Susan and David 17 times. ==Conviction and sentencing==
