Garrison Brown's cause of death was a gunshot wound to the head, according to a Flagstaff, Arizona, medical examiner.

Two months after Garrison was found dead on March 5, the "Sister Wives" star's cause of death was confirmed in the Coconino County Medical Examiner's autopsy report, according to People.

The medical examiner ruled the 25-year-old's manner of death as a suicide.

Alcohol poisoning was noted as a contributing factor in the death of Garrison, whose real name was Robert Brown.

Analyses of Garrison's blood showed he had a .307% blood alcohol level at the time of his passing -- more than three times the legal limit of .08%.

The reality star was also found with traces of caffeine in his system, according to the report.

In March, Garrison was discovered dead at his Flagstaff home in an apparent suicide, Flagstaff police told People at the time.

In a statement to the outlet, Flagstaff Police Department's Lieutenant Charles M. Hernandez II said no foul play was suspected.

At the time, Garrison's parents Kody and Janelle Brown confirmed the heartbreaking news via their respective Instagram accounts.

"Kody and I are deeply saddened to announce the loss of our beautiful boy Robert Garrison Brown," the statement read. "He was a bright spot in the lives of all who knew him. His loss will leave such a big hole in our lives that it takes our breath away. We ask that you please respect our privacy and join us in honoring his memory."

The family also posted a statement on Garrison's Instagram page.

"Our beloved brother/son Robert (aka Garrison) passed late last night. We appreciate the love and support from all those who have given it," the message read. "We ask that everyone please respect our privacy and space through this hard time."

According to a police report obtained by TMZ, Garrison sent out a concerning text message before his death.

"I want to hate you for sharing the good times. But I can't. I miss these days," the text, which was sent to a group of people, reportedly read.

According to the report, Janelle spoke to her son shortly after reading his text, though the exact details of their conversation were not disclosed.

However, Garrison allegedly stopped responding to texts shortly after, causing the worried mother to ask her other children to check on their brother.

After volunteering to visit his brother, Gabriel found Garrison dead with a gun in his hand at the home he shared with several roommates.

Garrison's roommates reportedly claimed that the TLC alum had been dealing with familial and substance abuse issues.

Janelle reportedly told cops that her ex Kody and their son were estranged and had not spoken in a while.
