Cause of death revealed for Garrison Brown, son of ‘Sister Wives’ stars Janelle and Kody Brown

The cause of death for “Sister Wives” alum Garrison Brown, who tragically passed away in March at the age of 25, has been revealed.

According to an autopsy report obtained by USA TODAY from the Coconino County Health and Human Services Medical Examiner’s Office, Brown died from a gunshot wound to the head, with the manner of death ruled as suicide.

The report also highlighted ethanol intoxication (alcohol poisoning) as a significant contributing factor. Brown’s blood alcohol level (BAC) was 0.307% according to an iliac blood analysis and 0.370% per a vitreous analysis. The Cleveland Clinic notes that a BAC over 0.40% is considered potentially fatal.

Flagstaff Police Department spokesperson Sgt. Jerry L. Rintala confirmed Brown’s death to USA TODAY in an emailed statement on March 5. Officers discovered Brown “deceased as a result of an apparent self-inflicted gunshot wound,” and there was no indication of foul play.
