A MISSING dad quit his job just days before vanishing on a camping trip with his ex-girlfriend and their daughter, his family has revealed.
Hansen’s sister Kelly told NBC News that she’s worried “something bad” may have happened on the trip.
She said: “It kills me to know that he’s changed and my niece, God forbid, is suffering because of this.
“I’m worried that Nick snapped and did something stupid. I’m worried that Jill could have snapped and did something stupid.”
She revealed that Hansen quit his job after losing custody of two of his other kids from a previous relationship.
Kelly said recent years have “not been kind” to her brother.
And, Hansen’s sister Kris Martin told The Sun that his mind wasn't stable.
Police released surveillance footage of the trio shopping at the supermarket as part of their missing person probe.

Hansen was pictured standing by the shopping cart.
Sanford Police Lt Matthew Gagne said they were buying food from the store.
He said: "There did not appear to be anything nefarious or criminal."
The family was also spotted at the Coos Canyon Campground in Byron.
The footage showed both parents carrying their daughter.
Sidebotham was due to return home from the trip on June 30 but failed to do so.
Her mom warned her daughter not to go camping, according to a family Facebook post.

And, he told WMTV: “This is not in her (Jill’s) nature to do anything like this. She’s never done anything like this.”
Jill's family claimed her phone was turned off on June 28, but her fiancé Corey Alexander, 31, said he received messages from her Facebook account the next day.
But, he admitted that he wasn't sure that the texts came from Jill's phone.
Alexander doesn't suspect that Hansen sent the messages but fears if he saw them, "they may have set him off".
He revealed that their final in-person conversation was about the apartment that the couple were due to move into over the July 4 weekend.
Detectives have received several tips but none so far have led to anything substantial.
But, Kris said she couldn’t imagine that Hansen has left Maine.
