It's May 1st, 1987.
30-year-old Brian MacAlister had just been in a heated argument involving three other men at Billy's Lounge on Millbury Street.
Brian left the other men and hopped into his brown 1973 four-door Oldsmobile parked outside of the Maurice the Pants Man store.
Brian, likely intoxicated, left the driver side door open to his car as he tried to tune a portable radio and smoke a cigarette.
Brian's killer approached the vehicle…and fired a single gun shot into the side of Brian's head.
