LOS ANGELES — Former “Eight is Enough” child star Adam Rich died of the effects of the drug fentanyl, the medical examiner’s office has ruled.

The death of Rich, who was 54, was ruled as an accident, an autopsy report from the Los Angeles County Medical Examiner’s Office says.

Rich was discovered dead at his home in the Brentwood Heights neighborhood of Los Angeles on Jan. 7 during a welfare check.

The property manager entered the home after noticing the keys in the front door, according to a case report.
