Authorities have said the suspects and officers exchanged gunfire and the brothers also lobbed explosives at police in their attempt to escape.
Donohue also said he hasn’t heard anything new on the investigation into who may have fired the bullet that pierced his groin and almost killed him. He has said in the past that it didn’t matter to him if the bullet turned out to be from an officer’s gun, saying officers did their jobs in the chaotic encounter that also resulted in 26-year-old Tamerlan Tsarnaev’s death.
A spokeswoman for the Middlesex district attorney said the investigation into the shooting is ongoing.
Dzhokhar Tsarnaev, 19, is awaiting trial on federal charges that include use of a weapon of mass destruction to kill, an offense for which authorities could seek the death penalty.
MBTA Police Chief Paul MacMillan walked out of the hospital with the Donohues on Friday morning, before a convoy of police vehicles pulled away from the hospital to escort the couple home.
“It’s just a remarkable story that he is where he is today,” MacMillan said, adding that he looked forward to having Donohue back on duty.
“As soon as he’s ready, we’ve got a uniform for him and we’ll put him to work.”
Friday also marked the day before the deadline to apply for aid from the primary victims’ compensation fund, which has grown to more than $47 million since Boston Mayor Thomas Menino and Gov. Deval Patrick established it shortly after the April 15 attack.
The One Fund received 188 applications for funding by the end of the day Friday, according to deputy administrator Camille Biros. More applications were expected Saturday as the deadline arrived.
Donohue is among those eligible for aid, along with the more than 260 people injured in the bombings, the families of the three people who died that day, and the family of slain Massachusetts Institute of Technology Officer Sean Collier. Authorities have said the bombing suspects fatally shot Collier while they still were at large.
