Boston police executed a search warrant Friday at the home of one of the Mattapan murder victims.
Officers parked a mobile command post outside 23 Sutton Street and went into the home of 21-year-old Sean “Simba” Martin at 11:40 a.m.
The house is just around the corner from the murder scene on Woolson Street, where Martin, his girlfriend 21-year-old Eyanna Flonory, her 2-year-old son Amani and 22-year-old Lavaughn Washum-Garrison were found shot to death early Tuesday morning.
A fifth victim, 32-year-old Marcus Hurd, is still in critical condition.
Investigators suspect the motive for the shootings was a drug deal gone bad.
Police have already found Hurd’s stolen SUV, which was seen speeding away from the shooting scene, and weapons that may be linked to the attack.
There have been no arrests yet.
