Erin Moran, the actress who played Joanie Cunningham on the hit TV series "Happy Days" has died in Indiana at the age of 56, police said.

TMZ first reported the death. The Harrison County, Indiana, sheriff's office told NBC News that dispatchers got a 911 call for an unresponsive female at 4:07 p.m. Saturday and first responders found Moran deceased.

Moran was just 13 when the show began in January of 1974. Viewers watched her mature on the show, which Moran said in a 2008 interviewwith the "Today" show wasn't the easiest passage to go through.

"It was so much fun with these guys," she said. "They made it better, they made it easier. I loved it. I had such a good time."

Moran played Joanie Cunningham, the younger sister of Richie Cunningham, who was played by Ron Howard. Her character was a love interest of the character Chachi, played by Scott Baio.

The sitcom set in the 1950s in Milwaukee, which ran from 1974 to 1984, was a hit. Moran also co-starred along with Baio in the short-lived spinoff "Joanie Loves Chachi," which began in 1982.

Moran and Baio returned for the "Happy Days" final season, which ended with the two characters getting married.
