DORCHESTER (CBS) — A teenager from Dorchester was formally charged Friday with murdering another teen from Dorchester at the beginning of May.
Nhu Nguyen, 19, is charged with shooting and killing Derek Matulina, 19, at the Savin Hill MBTA station on May 7.
Nguyen was ordered held without bail and expected to be back in court on June 21.
Prosecutors say Nguyen and Matulina knew each other before the deadly confrontation, and there had been other incidents leading up to this one. They said there was an argument outside the T station on the day of the shooting and it continued up to the platform.
At that point, investigators said Matulina came at Nguyen from behind and hit him several times with a padlock wrapped in a bandanna.
A third person separated at the two and then Nguyen pulled a gun from his waistband and shot Matulina once in the chest. He was able to run a short ways and call 911 before collapsing. He died at Boston Medical Center.
Nguyen was arrested three days later at a friend’s house in Portland, Maine.
