Boston Police Commissioner Edward F. Davis and Suffolk County District Attorney Daniel F. Conley today announced the arrests of two men in connection with the murder of 36-year-old Tyrone Smith on Stanwood Street.An extensive investigation by Boston Police homicide detectives and Suffolk prosecutors identified Trevon Mason, 22, and Daryl Pullen, 21, both of Dorchester, as shooting suspects in Smith’s January 7, 2009, homicide. Based on evidence developed in the course of their investigation and in the Suffolk County Grand Jury, homicide detectives today secured arrest warrants for both suspects. On Wednesday, January 7, 2009 around 9:21pm, officers from District B-2 (Roxbury) responded to a radio call for a person or persons shot in the area of 96 Stanwood Street in Dorchester. On arrival, officers located two individuals suffering from apparent gunshot wounds. The two victims, a 36 year-old male and a 36 year-old female were both transported to Boston Medical Center, the male with life threatening injuries, and the female with non-life threatening injuries. Mr. Smith was pronounced after arriving at the hospital. Commissioner Davis stated, “The hard work of initial responding officers, dogged detective work and dedicated prosecutors led to the successful apprehension of the perpetrators responsible for Mr. Smith’s death. Davis added, “Today’s arrests are evidence that people will be held accountable for senseless gun violence on our city streets.” "On the streets of Boston and behind the closed doors of the grand jury, police and prosecutors are working hand in hand toward the same goals -- safe streets for residents and accountability for violent offenders," Conley said. "If today's arrests don't bring comfort, I hope they can at least bring some satisfaction to Mr. Smith's family and loved ones as they continue to mourn his loss." Boston Police executed arrest warrants today and both men are expected to be arraigned on murder and related charges later this week in Dorchester District Court.
