“Happy Days” star Erin Moran has died

It’s a sad day for family, friends, and fans of Happy Days‘ Erin Moran, 56, who was found dead in her home on Saturday after first responders received a 911 call. The cause of death is still unconfirmed and pending an autopsy.

Moran played Joanie on the legendary sitcom, and already her former costars have been paying tribute to her on social media. Ron Howard, who played Richie, tweeted, “Such sad sad news. RIP Erin. I’ll always choose to remember you on our show making scenes better, getting laughs and lighting up tv screens.”

Henry Winkler, aka The Fonz as Happy Days fans know him, felt the same. “OH Erin… now you will finally have the peace you wanted so badly here on earth,” he tweeted.
