NEW YORK (AP) — Erin Moran, the former child star who played Joanie Cunningham in the sitcoms “Happy Days” and “Joanie Loves Chachi,” has died.

Police in Harrison County, Indiana, said that she had been found unresponsive Saturday after authorities received a 911 call. The Harrison County Sheriff’s Office said Monday that “a subsequent autopsy revealed that Mrs. Moran likely succumbed to complications of stage 4 cancer.” The type of cancer was not disclosed.  Moran had endured numerous struggles in recent years.

She was reportedly kicked out of her trailer park home in Indiana, according to tabloid reports, because of her hard-partying ways.

Moran previously said that she had been working on a memoir, called “Happy Days, Depressing Nights.”

Moran was already a veteran actress when in 1974 she was cast in “Happy Days” as Joanie, the kid sister to Ron Howard’s Richie Cunningham in the sitcom set in the 1950s. She would later appear with Scott Baio in the “Happy Days” spinoff “Joanie Loves Chachi.”
