Kassandra R. Sweeney and her sons, Benjamin, 4, and Mason, 1, were found dead in their home at 56 Wethersfield Drive about 11:30 a.m. on Wednesday. Each had died from a single gunshot wound, according to the attorney general’s office. Investigators have identified “all parties involved” and said there is no risk to the general public, according to the release. They have not given further details. Investigators had not made any arrests in the case as of late Saturday morning, Michael Garrity, a spokesman for the attorney general, said in an e-mail to the Globe. New Hampshire State Police and other law enforcement agencies will search for evidence Saturday in the areas of Shaker, Tilton and Laconia roads, as well as the on-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 local residents and stay away from properties in the search area and allow investigators to complete their work.” The search activity is not the result of new information in the case, but is part of an “ongoing investigative process,” said the statement, which was released by Attorney General John M. Formella, State Police Col. Nathan Noyes and Cmdr. of Northfield Police. John Raffaelli. Sweeney’s Wethersfield Drive home is on a side street off Shaker Road and is about 2 miles from the Route 93 exits at Laconia Road. Tilton Road connects Laconia Road with Shaker Road and passes north of the Sweeney 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 have been in contact with who has been very cooperative and helpful in this investigation,” Ward said. “Our victim witness advocate is working with him and his family and providing services. He is obviously extremely devastated as a result of these crimes.” Sweeney’s family has set up a GoFundMe fundraiser to help with the costs of memorial services and living expenses. In a message posted on the website, family members asked for privacy. John R. Element of the Globe staff contributed to this report. John Hilliard can be reached at [email protected]
