A New Hampshire mother shot dead her cancer-battling husband and their two young children before turning the gun on herself, according to state prosecutors who said they are investigating the killings as a murder-suicide.

Emily Long, 34, who had spoken about her struggles with depression online only two days earlier, carried out the killings early Monday inside the family’s home on Moharimet Drive in Madbury, a small town in the Seacoast region northwest of Portsmouth, according to the New Hampshire Attorney General’s Office.

Police responded to the scene just before 8:30 p.m. after a 911 call reported multiple people dead inside.

Emily, who, according to her LinkedIn, was the director of operations at a New Hampshire restaurant chain, posted on TikTok Saturday to her nearly 8,000 followers, admitting her children were “definitely struggling” and that she had been “really depressed,” per the outlet. She said she was trying to reestablish healthy routines and a sense of normalcy at home as her husband’s health worsened.

“I am determined to create normalcy,” Emily said in the video, adding that she was trying to get dressed in proper clothes more often. 

“I have been struggling so much and really depressed and have really become reclusive and just wanted to be with my kids and my husband. That being said, I’m making a change and it is starting today … And I’m making a point to get out of my depression and do this for my family.”

The attorney general’s office said there is no known threat to the public and that no updates will be given until after all autopsies have been conducted.

Neighbors said the Longs appeared to be a perfect family.

“It was shocking,” neighbor Bevy Ketel told WBZ-TV. “It was a perfect family, as far as we knew.”

“It’s so sad to think that that little girl is gone,” Ketel added, noting Ryan was well-known in the town.

“He certainly touched a lot of lives. He was part of the fabric of the community, and his family went along with it.”

Ketel said the children had recently set up a stand to sell lemonade to neighbors.

“It’s just shocking. We didn’t see it coming,” she said.
