Man convicted in 2014 fatal stabbing outside Dorchester barbershop

BOSTON — A Malden man has been convicted of stabbing a 29-year-old man to death outside of his Adams Street barbershop in 2014.

Dominic Shiner, 36, has been convicted of voluntary manslaughter for the December 12, 2014 stabbing that left 29-year-old Sean Dwyer dead and witness intimidation for sending grand jury transcripts from the Nasha Street Jail to a friend with a note saying "you know what to do."

During the seven-day trial, officials released evidence and testimony proving Shiner and Dwyer knew each other and that Shiner had visited the barbershop asking for money two days before the stabbing.

"Mr. Dwyer’s loved ones have waited years for this day to come," said Suffolk Co. DA Daniel Conley. "I hope they take some satisfaction in the jury’s verdict and know that prosecutors and police detectives never rested in their efforts on Sean’s behalf. Any mother, father, son, or daughter who loses a loved one to homicide can count on that dedication and support."

Shiner will be sentenced on Wednesday morning.
