A man who prosecutors say killed two men and injured a child when he opened fire on a group of people at a Boston public housing development four years ago has been found guilty of two counts of first-degree murder.

Wilvin Guity-Beckels was convicted Thursday and faces sentencing on July 12, according to the Suffolk district attorney's office.

Guity-Beckels got out of a car just before 10 p.m. on May 4, 2018, walked into the complex in the city's Jamaica Plain neighborhood, and fired on a group of about 15 people in an outdoor park, prosecutors said.

Boston man charged with two counts of first degree murder.

Christopher Joyce, 23, and Clayborn Blair, 58, were killed and a bullet grazed the ear of a 4-year-old boy. The men were the innocent victims of gang violence, police said. Joyce was killed just before his college graduation, and Blair was a father of three.

Guity-Beckels was linked to the shooting through surveillance video.

"These verdicts can never provide what the victims’ loved ones want and truly deserve — to have their loved ones back in their arms — but they help ensure that the individual who took their lives will not have the opportunity to inflict harm in the community again," Suffolk District Attorney Kevin Hayden said.
