Updated, 8:50 a.m., Thursday.
Two Boston Police officers were critically injured in a gunfight that broke out when they responded to a domestic-violence call around 10:50 p.m. at 136 Gladstone St.
The Herald reports the suspect, Kirk Figueroa, 33, of East Boston, opened fire on the officers with an assault-style rifle - and was wearing body armor.
Police returned fire and killed Figueroa, whose body was recovered from the building's basement.
Police report Thursday morning the two officers are both out of surgery and remain in critical condition.
Nearby residents were asked to shelter in place as Boston and State Police sweep the area for additional possible suspects, although by 11:50 p.m., police determined there were no other suspects and lifted the request.
As it does with all officer-involved shootings, the Suffolk County District Attorney's office has launched an investigation.
