Former child star Adam Rich died in January due to the "effects of fentanyl," according to a report from the Los Angeles Medical Examiner's Office.

In addition to "Eight Is Enough," Rich's other television credits included "Dungeons & Dragons," "Baywatch," "Small Wonder," "Gun Shy," "Code Red" and "CHiPs."

In recent years, Rich had stayed away from working in front of the camera. He last appeared as himself in the 2003 film "Dickie Roberts: Former Child Star" and played Crocodile Dundee in a 2003 episode of "Reel Comedy."

Over the course of his life, Rich was arrested for attempted burglary as well as driving under the influence.

Rich's death was announced by his representative Danny Deraney in an emotional statement that he shared on Twitter.

"Adam was simply a wonderful guy. He was kind, generous and a warrior in the fight against mental illness," Deraney wrote. 

"Adam did not have an ounce of ego. He was unselfish and always looked out for those he cared about. Which is why many people who grew up with him feel a part of their childhood gone, and sad today," he continued."He really was America's Little Brother."
