Convicted small-time coke dealer charged with August murder on Deering Road in Mattapan

Dewane Tse, 34, is slated for arraignment today for a triple shooting on Aug. 14, 2018 on Deering Road that left one man dead, the Suffolk County District Attorney's office reports.

Tse has been held without bail since his arrest and arraignment in Dorchester court on April 30 for the death of Yashua Amado. Today's arraignment in Suffolk Superior Court comes after his indictment for the shootings.

In 2010, Tse was sentenced to 21 months in federal prison, followed by 36 months of supervised release, after pleading guilty to federal charges of possession of cocaine with intent to distribute and distribution of cocaine - for the $80 of cocaine he'd sold to an undercover Boston drug-unit detective outside the Boston Medical Center emergency room the year before.

Innocent, etc.
