A Dorchester man was held without bail today following his arrest and arraignment for allegedly stabbing 42-year-old Tai Yee to death last night, Suffolk County District Attorney Daniel F. Conley said.

THANH VAN TRUONG (D.O.B. 1/1/55) was charged with a single count of murder for allegedly stabbing Yee in the chest at about 9:30 last night, causing an injury that later claimed Yee’s life at Boston Medical Center. Dorchester District Court Judge Robert Tochka ordered him held without bail.

Prosecutors believe the two men were arguing inside Truong’s apartment prior to the fatal altercation and were among several people present at the time. At some point, that altercation spilled outside and escalated into a physical fight. It was during that fight, prosecutors say, that Truong stabbed Yee with a steak knife.

The nature of the argument and the relationship between the two men remains under investigation, Conley said.

Boston Police responded to the area of Truong’s Lyon Street residence shortly after 9:30 to find Yee wounded. Yee was able to identify Truong as his assailant, authorities said. The wounded Dorchester resident was transported to Boston Medical Center where he succumbed to his injuries at about midnight.

Based on their ongoing interviews and the evidence recovered at the scene, homicide detectives placed Truong under arrest early this morning.

Assistant District Attorney Jennifer Hickman of Conley’s Homicide Unit is prosecuting the case and Catherine Yuan is the assigned victim-witness advocate. Attorney Jack Miller represents the defendant, who will return to court on July 8.
