A heartbreaking new discovery inside the abandoned pickup truck has fans in tears – could this be the REAL reason the beloved Alaskan Bush People star took his own life with that mysterious g.u.n?The coroner’s office has listed his official cause of death as a “single penetrating gunshot wound to the head,” and said that the reality TV star died by suicide, according to TMZ. Matt’s autopsy also revealed that there were methamphetamines in his system when he took his life, and that “subsequent immersion in water (river)” contributed to his passing. He was 42 years old.

“I would have never suspected he would have hurt himself, honestly,” Bear said. “He struggled for a long time, as I’ve mentioned. And I worried he was going to end up, like, OD’d or something like that. I didn’t think he would hurt himself.”

A day later, Bear posted a lengthy Instagram caption alongside of a photo of him and Matt. “To millions of viewers, Matt was known as one of the original stars of ‘Alaskan Bush People.’ To us, he was so much more,” he wrote. “Matt was intelligent, curious, creative, and endlessly fascinated by the world around him. He was a gifted outdoorsman, fisherman, boatman, artist, and lifelong learner. He loved adventure, nature, and discovering new things. Matt had an extraordinary mind. He taught himself sign language, studied Egyptian hieroglyphs, petroglyphs, and Sanskrit, learned conversational Spanish, and could spend hours mastering a new skill simply for the joy of understanding it.”
