A jury convicted a 30-year-old Dedham man accused of shooting and killing a man who was at a barbershop with his son in 2016 on a murder charge Friday, prosecutors said.

William Shakespeare was inside the Hair It Is barbershop on Blue Hill Avenue in Mattapan when 31-year-old Marcus Hall entered with his 4-year-old son in June 2016.

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

Shakespeare ran from the barbershop, prosecutors said, but returned later and shot Hall five times, killing him. Shakespeare left for New York where Boston police arrested him last year.

"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.

The jury convicted Shakespeare of first-degree murder and unlawful possession of the firearm used to kill Hall.

Shakespeare is scheduled for a sentencing hearing Monday at 9:30 a.m. in Suffolk Superior Court.
