The cause of death of actor Jackson Odell has been revealed.

According to the Los Angeles County Medical Examiner, the 20-year-old has died of an overdose in a sober establishment. The coroner’s report ruled that Odell’s death was an accident resulting from “acute heroin and cocaine toxicity”.

The toxicology report confirmed speculation that narcotics were involved. Odell “had a history of heroin addiction,” said Ed Winter, deputy chief of investigations at the coroner’s office, at USA TODAY.

On June 8, Odell was found in a sober facility, where he was being treated, said the coroner’s office. He was declared dead on the scene.

The actor played Zeke in the 2011 film “Judy Moody and The Not Bummer Summer”, based on the children’s book series Megan McDonald, and played a recurring role in the television series ABC “The Goldbergs” under the name Ari Caldwell. He appeared in episodes of “Modern Family” and “Arrested Development”.

He died one month before his 21 years.

Odell’s family called him “a bright, loving and talented soul”.

“It will always be a bright light,” their statement said. “He had so much more to share. Our family will always convey this truth. Our wish is that the rest of the world who knew and loved it too. “
