A MOM shot dead her husband who was battling cancer and killed her two eldest children before turning the gun on herself, it has emerged. 

Emily Long carried out the shootings in their New Hampshire home – just days after she shared a chilling video on TikTok where she spoke about her struggles.

The four people were found dead on Monday night, which sparked an initial mystery. 

New Hampshire investigators have since ruled their deaths as a murder-suicide. 

Emily, 34, shot her husband Ryan, 48, several times in the early hours of Monday morning, as reported by the CBS affiliate WCAX-TV.

She shot her children Parker, eight, and Ryan, six, once in the head.

Coroners ruled that Emily died from a single gunshot wound. 

Cops found a toddler, three, inside the family’s Madbury home, who was unharmed. 

A motive behind the shootings still remains unknown as cops continue their probe. 

Police said they found a gun inside the plush property.

Emily was active on social media and spoke about her husband’s battle with glioblastoma. 

Glioblastoma is an aggressive brain cancer for which there is no cure. 

On social media, she documented her husband’s cancer battle, reflecting on moments where she told her children about his illness.

In a candid video, she explained how she wanted to create normalcy for her children. 

Emily admitted her children were having a “hard time” amid his cancer battle.

PERSONAL BATTLES

She also spoke about her own battles on social media.

In a now-deleted TikTok clip, she revealed she wanted to make a “change” as she had been struggling with depression.

“Today I decided I need to make a conscious effort to shift my mindset,” she told her social media followers.

“I’m getting out of this depression whether I want to or not.”

The family lived in Madbury – a town of less than 2,000 people. 

And, locals in the area have been left stunned by the deaths of the four family members.

“It was shocking,” Bevy Ketel, a neighbor, told the CBS affiliate WBZ-TV.

Ketel recalled how the children had recently set up a lemonade stall. 

“We didn’t see it coming,” she admitted.
