Third Suspect Charged in Shootout at Forest Hills Station

Investigators have identified a second shooter in the gun battle that left the Forest Hills MBTA station in lockdown last week.

Three people were arraigned Tuesday in connection to a shooting outside of the crowded Forest Hills MBTA station in Jamaica Plain last week.

Kisean Parker, 18, of Roxbury, Kevasia Lowe, 18, of Mattapan, and Robert Acosta, 18, of Dorchester, appeared in West Roxbury District Court on charges for allegedly opening fire on each other following a scuffle on an MBTA bus.

Parker is charged of unlawful possession of a firearm, unlawful possession of ammunition, discharging a firearm within 500 feet of a building, and assault with a dangerous weapon. Lowe was arraigned charges of unlawful possession of a firearm, carrying a dangerous weapon, and assault with a dangerous weapon. Both were ordered held on $15,000 bail, to abide by a curfew and to stay away from witnesses and victims.

Acosta is charged with unlawful possession of a firearm, unlawful possession of ammunition, discharging a firearm within 500 feet of a building, and assault with a dangerous weapon. He was ordered held on $25,000 bail.

Parker became involved in a verbal altercation with several individuals on board an MBTA bus that spilled into the street after the bus arrived at the Forest Hills Orange Line station shortly before 8:00 a.m. Friday, prosecutors said in court.

Parker allegedly pulled out a firearm and opened fire on the individuals as they fled from the area of Asticou Road and Washington Street. Prosecutors said a second man returned fire.

Images of the second gunman were captured by public safety cameras at the MBTA station and Acosta was identified as the person in the images by Boston Public School police and officials.

Lowe allegedly threatened one victim with a Taser device during the altercation, prosecutors said.

Boston and Transit Police officers interviewed witnesses and victims and located spent shell casings in the area where the shots were fired. Additional officers detained Parker and Lowe not far from the scene, and a witness positively identified Parker as the gunman, prosecutors said. A firearm and a Taser were found in Lowe’s handbag upon arrest.

Parker, Lowe, and Acosta will all return to court Nov. 12.
