Scott Baio is defending himself over remarks he made about the death of former co-star Erin Moran. Speaking on a radio show Monday, Baio, who believed his "Joanie Loves Chachi" co-star died of a heroin overdose, criticized the actress. "You do drugs or drink, you're going to die," he said. What Baio didn't know at the time was that Moran actually died of stage 4 throat cancer. He is now defending himself in an interview with Inside Edition.
