Witnesses suggest friendly fire felled MBTA officer

Eyewitness accounts strongly suggest that MBTA Transit Police Officer Richard H. Donohue Jr. was shot and nearly killed by a fellow officer in Watertown April 19 during the hail of gunfire unleashed on Dzhokhar Tsarnaev as the suspected terrorist made a getaway in a carjacked sport utility vehicle.

Donohue went down in the early-morning darkness during an extraordinary gunfight in which at least a dozen police ­officers from four departments exchanged up to 300 rounds of gunfire with Dzhokhar’s older brother, Tamerlan Tsarnaev. The Tsarnaevs also allegedly set off explosives, including a pressure cooker bomb similar to the ones used in the Boston Marathon bombings.
