Erin Moran, the former Happy Days child star who was found dead at her Indiana home over the weekend, likely died of cancer, according to the Harrison County Sheriff's Office and the county coroner.
A statement released by authorities Monday said that an autopsy found that Moran "likely succumbed to complications of stage 4 cancer."
Toxicology tests were performed and results are pending, but "no illegal narcotics were found" at Moran's residence in New Salisbury, Ind., about 20 miles from Louisville, Ky.
The statement did not say what kind of cancer Moran had.
