On the morning of August 14, 2018, 29-year-old Yashua Amado was fatally shot in Mattapan Square, Boston. Amado and a friend had just picked up breakfast and were sitting in his parked car on Deering Road at about 9:46 a.m. when an unidentified gunman exited a red GMC Acadia, approached the vehicle and fired multiple shots into the driver’s side and windshield. Two other people were wounded in the same attack; Amado was killed.

Investigators traced the rented red GMC Acadia to 37-year-old Dewane Tse of Providence, Rhode Island. Security camera footage placed the Acadia in the area before Amado arrived, showed the SUV following Amado’s car, and recorded the vehicle being returned to a Government Center parking garage about an hour after the shooting. Those leads led to Tse’s arrest and prosecution; a jury convicted him of first-degree murder and armed assault with intent to murder in December 2021, and he was sentenced in January 2022.

The person who fired the shots that killed Amado has never been identified and remains at large. Does anyone have information about the red GMC Acadia, its occupants that morning, or the shooter seen near Deering Road in Mattapan Square?
