The state's highest court ruled Monday that one of two men convicted of first-degree murder in the killing of an innocent bystander during a confrontation in Dorchester should get a new trial.
Wesson Colas was convicted in the killing of 26-year-old youth worker Dawnn Jaffier, and the non-fatal shooting of another woman, near Dorchester's J'ouvert Parade, a Caribbean festival, in 2014.
Though Colas didn't fire a shot, prosecutors said he was equally responsible as the gunman, Keith Williams, because Colas pointed a weapon at the rival with the intent to kill and therefore participated in the gun battle. Williams was also sentenced to life in prison for first-degree murder.
