Actor Scott Baio is in hot water following the death of his former Happy Days co-star Erin Moran, after he suggested that a life of drugs and alcohol had eventually killed her.

Baio made the comments following initial reports that the star had died from a suspected heroin overdose. A coroner's report then disclosed the 56-year-old Moran had stage 4 cancer.

Baio had appeared to display little sympathy for her before that, however. During an interview with WABC Radio , he claimed she only had herself to blame for her demise.
