According to an autopsy conducted by the Okanogan County Coroner in Washington and obtained by Page Six, Brown’s manner of death was ruled a suicide caused by a single penetrating gunshot wound to the head.

The autopsy noted the contributing circumstances were subsequent immersion in water — in this case a river — and that he was under the influence of methamphetamine.

Brown’s body will now be released to his family for final arrangements.

On May 27, a witness called 911 after spotting a man, later identified as Brown, wading in the Okanogan River near Oroville, Washington.

The witness briefly turned away, then turned back after hearing a loud noise. That’s when they allegedly saw Brown floating face-down in a swift current.

A day later, the reality star’s younger brother Bear Brown said he had “some really bad news” and had been told that Matt “took his own life.”

Bear, 38, said Matt “was seen in a river, at a river or close to a river” and later “floating down the river” and that someone then “called police,” who have been “trying to find the body.”

“All the witnesses are saying that it was Matt,” Bear lamented. “Someone definitely did, and a lot of people are thinking that it’s him. … It looks like it is. … It’s looking very likely that it is the case.”

Bear claimed his older brother had “been struggling for a long time with alcohol and with drugs” and claimed that Matt allegedly “didn’t want anything to do with the family.”

Bear later confirmed that authorities identified the body that was found in the Okanogan River as his brother.

“They found a body in the river a few hours ago and it was positively identified as being Matt,” he said in a TikTok update.

Bear said his and Matt’s youngest brother, Noah Brown, was the first family member to see Matt’s body and that he assisted in the recovery efforts.

“Noah helped them pull the body out of the water and Noah identified [Matt],” he said.

Bear said he believed Matt died by suicide.

“I would’ve never thought that Matt would hurt himself. It does look as though it was self-inflicted,” Bear said at the time.

Matt was a cast member of Discovery’s reality show “Alaskan Bush People” from its debut in 2014 until 2019.

The series followed the Brown family’s life in the Alaskan wilderness.
