Matt Brown's cause of death at 43 has been determined days after the "Alaskan Bush People" star's family announced his body had been recovered in Washington state.
Brown's manner of death was determined to be suicide, the Okanogan County Coroner confirmed to USA TODAY on June 3. The cause was a gunshot wound, and contributing circumstances included being "under the influence of methamphetamine" and his "subsequent immersion" in a river.
TMZ was first to report the news.
