Bristol — Officer Alec Iurato shot and killed Nicholas Brutcher, suspected of luring three Bristol police officers into a fatal shootout earlier this week, police said Saturday .

Police, in a Facebook post honoring the slain officers, Sgt. Dustin DeMonte, 35, and Officer Alex Hamzy, 34, said that Iurato "was struck by gunfire" during an ambush, then "returned fire and killed the suspect."

The new details come as sources told Hearst Connecticut Media Group that Brutcher came into contact with officers hours before the late Wednesday shooting.

Nicholas Brutcher interacted with police at Bleacher's Bar on Middle Street earlier in the night, according to sources. The details of that interaction were not immediately available.

Richard Goodine, an attorney who represents the bar, has not responded to phone calls on Thursday and Friday. A message was left at the bar seeking comment Saturday.

State police have said the officers were lured to a Bristol home by a caller reporting a "possible domestic" incident between two brothers, Nicholas Brutcher, and his younger sibling, Nathan Brutcher, according to Connecticut State Police. Authorities, who have not revealed a motive, said Nicholas Brutcher was the shooter.

Security video obtained by Hearst Connecticut Media Group reveals the sound of dozens of gunshots over a span of two minutes as the Bristol officers were slain.

The initial series of shots included about 30 rounds, fired over the course of six to seven seconds, as heard in the video footage from a nearby apartment complex. About a minute later, a single shot is heard. About 15 seconds later, more than 20 shots ring out, seemingly muffled or farther away. A little more than 30 seconds later, two more shots are heard.

The shootings rocked the city of Bristol and the entire state, especially the law enforcement community who showed up in droves to escort Hamzy and DeMonte's remains to the medical examiner's office.

On Friday, Commissioner James Rovella of the state Department of Emergency Services and Public Protection, released a statement offering his condolences on behalf of the agency, which oversees the Connecticut State Police.

"What we thought was unimaginable became reality in less than a minutes time. Our hearts are broken but our service to our citizens is everlasting," said Rovella, who led the Hartford police department, where he started as a beat cop about a half-hour east of Bristol, before becoming commissioner.

"We will never forget our Bristol Police heroes," Rovella added.

The department also announced a fundraiser to benefit the DeMonte and Hamzy families, organized by the Bristol police union.

Donations can also be brought to the department or Thomaston Savings Bank locations, the department said, where the police union has established a fund for the affected families.
