A Dedham man has been sentenced to life in prison for the 2016 shooting of 31-year-old Marcus Hall behind a Blue Hill Avenue barbershop. William Shakespeare, 30, was arrested in New York City in January. His trial concluded its second day of jury deliberations on Aug. 10, returning a conviction of first-degree murder. Hall was found shot to death around 12:20 p.m. on June 14, outside the barbershop where his young son was getting a haircut prosecutors said.

According to the Suffolk County District Attorney’s office, Shakespeare was inside the 1178 Blue Hill Ave. barbershop when Hall and his 4-year-old son came in. The two men “had a tense verbal exchange followed by an argument in the parking lot,” the DA’s office said. After leaving the scene, Shakespeare returned a short time later and shot Hall during a second confrontation.
