Man gets life without parole for 2018 murder on Deering Road in Mattapan

A Providence man was sentenced to life without the possibility of parole today for a 2018 triple shooting that left Yashua Amado dead.

A Suffolk Superior Court jury had convicted Dewane Tse, 37, of first-degree murder last month and armed assault with intent to murder for the Aug. 14, 2018 shootings, the Suffolk County District Attorney's office reports. His sentence now goes to the Supreme Judicial Court, which reviews all first-degree murder convictions.

According to the DA's office:

On the date he was murdered, Amado and a friend picked up breakfast in Mattapan Square. While parked and sitting inside his car on Deering Road at 9:46 a.m, an unidentified gunman exited a red GMC Acadia and approached the victim’s vehicle. He fired multiple shots into the vehicle’s driver’s side and windshield. He then returned to the waiting SUV and fled the area.

Evidence gathered during the course of an investigation by detectives assigned to the Boston Police Department Homicide Unit proved that, two days prior to the shooting, Tse had rented a red GMC Acadia. Security camera footage from that morning depicted Mr. Tse’s vehicle in the area before Mr. Amado and one of the surviving victims arrived in Mattapan Square. Mr Tse’s vehicle then followed Mr. Amado’s vehicle as he and the surviving victim traveled up Blue Hill Avenue to Deering Road. The red SUV parked on Deering Road for about three minutes in total, allowing the gunman to exit the vehicle, blast the fatal volley of bullets and then re-enter the SUV before it fled the area. Security camera footage captured Tse returning the rented vehicle to the Government Center parking garage approximately one hour after Amado’s murder.

In 2010, Tse was sentenced to 21 months in federal prison after pleading guilty to selling $80 worth of cocaine to an undercover Boston drug-unit detective outside the Boston Medical Center emergency room the year before.
