Investigators were back out searching for evidence Wednesday in the ongoing investigation into the murders of a mother and her two young children found shot to death in Northfield, New Hampshire, last week.

Police responding to a 911 call on the morning of Aug. 3 found the bodies of 25-year-old Kassandra Sweeney and her two sons, 4-year-old Benjamin Sweeney and 1-year-old Mason Sweeney in their home.

Police are searching in Northfield and Tilton, New Hampshire, on Saturday as their investigation into the murder of a mother and her two young sons continues.

The New Hampshire Attorney General's Office said state police and other law enforcement agencies were in the area of Interstate 93 between exits 17 and 20 in Concord, Canterbury and Tilton on Wednesday as part of their continued investigation. They asked that motorists obey road signage in the area and provide investigators enough space to conduct their work.

"The search activity poses no danger to the public and will consist of a search for physical information," the attorney general's office said in a statement. "The search activity is not the result of new information in the case but is part of the ongoing investigative process. As previously announced, at this point in the investigation, investigators have identified all involved parties and there is no threat to the general public."

A mother and her two young sons were found dead in their Northfield, New Hampshire, home earlier this week.

Authorities conducted a previous search on Saturday in Northfield and Tilton, but have not said if they discovered any evidence related to the case.

Autopsies were conducted last week, and the chief medical examiner determined that all three family members died from single gunshot wounds. Their deaths have been ruled homicides.

No arrests have been made in connection with the triple murder investigation, and the attorney general has not named a suspect but said investigators have identified "all involved parties" at this point, and there is no threat to the general public. They do not believe the killings were a random event.

"Every other customer is coming in saying something about the gun and who did it," Barbara Moulton, who works at a local convenience store, told NBC10 Boston.

"The first three or four days people were really scared, like 'oh no who was it,'" she added.

Senior Assistant Attorney General Geoff Ward said last week that the attorney general's office has been in contact with the children's father, Sean Sweeney, and he has been "very cooperative and helpful in this investigation." He said the attorney general's victim witness advocate is working with him and his family.

"He is obviously beyond devastated as a result of these crimes," Ward said.

Sweeney spoke about the case for the first time in a Facebook post Sunday morning.

"I wanted to thank everyone for the outreach and support, while things will never be 'normal' again my body finally shut down and let me get some sleep last night and I woke up feeling as 'normal' as possible," he wrote.

Sweeney said he is "unable to confirm anything as to what happened and who is responsible" and called his wife Kassandra "the most amazing, caring, sweetest all around good person that anyone could ever meet...," while adding that she loved their children very much.
