BOSTON (AP) — Two men have been convicted in the shooting death of an innocent bystander at a Boston street festival in 2014.

Keith Williams and Wesson Colas were found guilty of first-degree murder Thursday in the death of Dawnn Jaffier.

Prosecutors say the men were rivals who confronted each other with guns near a Caribbean festival in Dorchester. Prosecutors say Williams fired, but Colas didn't.

A bullet killed Jaffier, a 26-year-old city youth worker.

Prosecutors said their case stemmed from a 1997 Supreme Judicial Court ruling that said a defendant who participates in a gun battle can be held liable for a death even if the defendant's opponent fired the fatal shot.

Williams' attorney has said his client was wrongly identified as the shooter.

Colas' attorney has said his client wasn't carrying a gun.
