A 30-year-old Dedham man will spend tomorrow, and tomorrow, and tomorrow in state prison after receiving a life sentence for a 2016 Mattapan slaying.

William Shakespeare was convicted last week of fatally shooting 31-year-old Marcus Hall at a Mattapan barber shop.

Shakespeare and Hall "had a tense verbal exchange followed by an argument in the parking lot," Suffolk County District Attorney Daniel Conley's office said in a news release.

Shakespeare at first ran from the barbershop, but returned and shot Hall five times, prosecutors said.

He then traveled to New York, where he was arrested in January 2017 and extradited back to Massachusetts.

A jury convicted Shakespeare of first degree murder and unlawful possession of a firearm on Friday.

"The verdict speaks for itself - this was a cold-blooded and vicious shooting in broad daylight, and the jury clearly saw it as such," Conley said in a statement after the trial was completed.
