N.H. investigators search area near Northfield home where mother, two sons were slain

Husband ‘beyond devastated’ by shooting deaths of wife and two children in N.H., cooperating with investigation

New Hampshire police searched Saturday near the home in Northfield, where a 25-year-old woman and her two young sons were shot dead last week, officials said.

Kassandra R. Sweeney and her sons Benjamin (4) and Mason (1) were found dead at their home at 56 Wethersfield Drive about 11:30 a.m. Wednesday. They had all died from a single gunshot wound, according to the attorney general’s office.

Investigators have identified “all parties involved” and said there is no danger to the general public, the statement said. They have not released any further details.

The detectives had not made any arrests in the case late Saturday, Michael Garrity, a spokesman for the attorney general, said in an email to the Globe.

The New Hampshire state police and other law enforcement agencies will search for evidence Saturday in the Shaker, Tilton and Laconia areas, as well as the ramp areas entering Route 93, the statement said.

“Due to the ongoing investigation, no additional information will be released at this time,” the statement said. “Officials are asking the public to respect the privacy of residents in the area and to stay away from properties in the search area and allow researchers to complete their work.”

The search activity is not the result of any new information in the case, but is part of the “ongoing investigation process,” the statement said, released by Attorney General John M. Formella, State Police Colonel Nathan Noyes and Northfield Police Chief. . John Raffaelle.

The Sweeney’s Wethersfield Drive home is on a side street off Shaker Road and about 2 miles from the Route 93 exits to Laconia Road. Tilton Road connects Laconia Road with Shaker Road and runs north from the Sweeneys’ home.

On Friday, Assistant Attorney General Geoffrey WR Ward said Sweeney’s husband — Sean M. Sweeney, who is the father of the two boys — is cooperating with police and prosecutors.

“The father is someone we interacted with who has been very cooperative and helpful with this research,” Ward said. “Our victim-witness attorney works with him and his family and provides services. He is clearly beyond devastated as a result of these crimes.”

Sweeney’s family has set up a GoFundMe fundraiser to help with memorial services and living expenses. In a message on the website, family members have asked for privacy.
