Two police officers who were shot dead in Connecticut had apparently been drawn into an ambush by an emergency call about possible domestic violence, authorities said Thursday.

State police said in a release that the 911 call Wednesday night about a dispute between two siblings appears to have been “a deliberate act to lure law enforcement to the scene” in Bristol.

Bristol Police Sgt. Dustin Demonte and Officer Alex Hamzy were killed. Officer Alec Iurato was injured.

Police said the suspect, Nicholas Brutcher, 35, was shot dead, and his brother Nathan Brutcher was wounded.

Police said the suspect, Nicholas Brutcher, 35, was shot dead, and his brother Nathan Brutcher was wounded.

The surviving brother, 32, was hospitalized, and it wasn’t immediately clear whether he or his family have an attorney or someone else who can speak for them.

Neighbor Danny Rodriguez said he was outside his home across the street when the gunfire rang out.

“I heard a whole war going on behind me,” he said. “It was so loud and crazy.” At one point, he said, a woman screamed, “You ... killed them!”

The deadly encounter came during a week when at least 11 police officers have been shot around the country.
