On the evening of July 26, 2020, 20-year-old Yaseen Butt of Revere, Massachusetts, was fatally shot after a confrontation that began when two backpacks were allegedly stolen earlier that day. One backpack was worth about $800.

Butt and friends located Martinez on Revere Beach Boulevard, where a confrontation escalated. Martinez is said to have tried to get a firearm from someone in his group, prompting Butt to retreat. Martinez and others chased Butt to a grassy area near 82 Revere Beach Boulevard; after Butt fell, he was beaten and then shot. First responders found him about 10:10 p.m.; he was taken to Massachusetts General Hospital and pronounced dead.

Security camera footage allegedly shows Martinez and others fleeing into an MBTA station, and Martinez jumping onto live tracks to evade a train. Four days later Martinez, an East Boston resident, was arrested and arraigned on murder, assault with a dangerous weapon, and two counts of armed robbery and held without bail. In subsequent months two 17-year-old males from East Boston were also arrested and charged in connection with Butt’s death.
