WATCH VIDEO: What We Know About the East Boston Police Shooting Suspect

BOSTON, Massachusetts (NECN) -- Two police officers were shot in an East Boston neighborhood late Wednesday and the suspect, who had an assault-style rifle and a ballistic vest, is dead, authorities said.

Both of the officers' underwent surgery at Massachusetts General Hospital and are still in critical condition, according to Boston Police Commissioner William Evans. Their names have not been released. One of the officers is a 28-year veteran on the force, while the other has served for 12 years.

The suspect has been identified as Kirk Figueroa, age 33, of East Boston.
Nine other officers were taken to Tufts Medical Center to treat minor injuries and emotional stress.

Authorities said officers were responding to a dispute between two roommates at 136 Gladstone St. just before 11 p.m., and when officers arrived, one of the roommates who was armed fired on police. The second roommate was not injured in the shooting.

The suspect was described to NBC News by a senior Boston police official as "heavily armed," and may have had as many as three firearms, including a weapon described as a "long gun/rifle."

Evans said early Thursday morning that the suspect, a 33-year-old man, had at least one assault-style rifle and a ballistic vest.

According to Evans, several officers entered the building after hearing gun shots and dragged out the injured officers while exchanging gunfire with the suspect.

One officer was able to put his hand inside an injured officer's wound and apply first aid.

Residents were asked to shelter-in-place or stay
away from the area as police briefly searched the area for a possible second suspect. The shelter-in-place has since been lifted and residents were escorted back to their homes.

Suffolk District Attorney Dan Conley pledged his office "will do a fair and thorough investigation."

Meanwhile, residents described the chaos in the immediate moments after the shooting.

"I saw a whole bunch of guns, and the shooting kept going, and [police officers] were running," resident Eric Dicrescenzo said.

He added, "I've never been that close to a shooting in an uncontrolled area, so I was kind of freaking out.

Tiara Willdigg, whose car was parked near the scene of the shooting, said she got a phone call from a friend about the shooting.

"I was coming outside and ran out of the house and I went up there, and as I'm up there, there's mad SWAT, just ran, ran, 'Get off the street, get off the street,' heard shots popping off," she said.

Evans said it's likely no officers in the East Boston shooting were wearing body cameras because the district isn't part of the department's pilot body camera program.

Governor Charlie Baker and Lt. Gov. Karyn Polito released a statement following the shooting that said, "Governor Baker and Lt. Governor Polito are shocked and saddened to learn of last night's horrific incident and their thoughts and prayers are with the police officers and their families."
