AMHERST — A 27-year-old man was arrested and charged with killing a 23-year-old at a home on Baboosic Lake Road early Thanksgiving morning, the New Hampshire Attorney General’s office said.

Bryson Peluso will be arraigned today at Hillsborough County Superior Court South on second-degree murder charges for the killing of Brandon Kluz with a handgun at 19 Baboosic Lake Road, state prosecutors said.

Earlier, authorities had said they were investigating a “suspicious death.”

Shortly after 1 a.m., Amherst Fire was dispatched to the Baboosic Lake Road home for a report of a person with a gunshot wound. In dispatch recordings, first responders can be heard administering CPR to the apparent victim. He later died, officials said.

At that time, the same dispatch recordings said authorities had a “man in custody.”

Senior Assistant Attorney General Peter Hinckley told reporters authorities responded to “numerous” 911 calls around 1 a.m. in the neighborhood.

“Witnesses are being interviewed; there are many aspects of this to follow,” Hinckley said Thursday.

There was no evidence of an ongoing threat to the public, the AG’s office said in a joint statement with New Hampshire State Police Major Crime Unit and local police.

An autopsy will be performed this morning by the New Hampshire Chief Medical Examiner’s office.

Peluso’s last known residence was 5 Sirelle Court in Nashua, an arrest he gave to Nashua police when they arrested him July 20 on an out-of-town warrant.

In October 2016, Nashua police arrested Peluso and charged him with simple assault, resisting arrest and criminal mischief.

In 2011, he gave a Greenfield address when Nashua police arrested him for simple assault.

On his Facebook page, Peluso said he was from Fitchburg, Mass., and had worked plowing snow. He also worked more recently as a mechanical installer and a plumbing apprentice.

He posted only last week about severely damaging his truck when he struck a utility pole trying to avoid a collision with another vehicle.

“Thanx everyone, concussion minor bumps; I’m good to go,” Peluso posted on Nov. 20.

“Truck can be fixed. I was trying to avoid the vehicle if there was a child in it or would rather cream a pole than take a life.”

On Thursday, several people posted on his Facebook page about the irony of the statement, given Peluso is now charged with murder.

In Amherst, neighbors said they saw law enforcement officials escorting other occupants of the Baboosic Lake Road home outside after 2 a.m. Thursday.

The Major Crime Unit remained at the scene until just before noon, according to witnesses.

The residents of the home had been living there only a few months, neighbors said.

According to property tax records, Diane J. Zahn bought the three-bedroom home on July 31 for $387,000. It was built in 1984.

Anyone with information can call Sgt. Mark Beaudoin of the Major Crime Unit at (603) 223-4381.
