Arrest made in connection with Mattapan murders

BOSTON -- An arrest has been made in connection with the murders in Mattapan on Friday night.

The Boston Police Fugitive Squad arrested 35-year-old Kimani Washington of 45 Fowler Street in Dorchester. He was arrested in Manchester, New Hampshire and was taken into custody.

Washington is now facing charges in connection with the Mattapan murders. According to a source, those charges include possession of a firearm and possession of a stolen vehicle. The vehicle is a Ford Edge SUV, which investigators located a short time after the homicides in Grove Hall, about two miles from the scene of the shooting.

According to a source, Washington was questioned at the scene not long after the incident, but it took investigators a few days to put some of the pieces together before they took him into custody.

Washington will be appearing in Manchester District Court on a "fugitive from justice" charge, and will be brought back to Dorchester District Court for a possible arraignment on Monday.

Washington has not been charged specifically with the murders, but is being questioned.

According to a source, other arrests may be on the way, but this was a “significant arrest” in connection with the murders of the four people in Mattapan earlier this week.

Boston Police have been executing several search warrants over the past few days, including the most recent one on Sutton Street. According to a source, it appears that something may have happened in that Sutton Street location, but they believe that the suspects actually shot the victims on Woolson Street on Tuesday morning around 1:00 a.m.

There is still no word on a motive.
