Erin Moran's final autopsy report was released Tuesday confirming the "Happy Days" star's death was not linked to drugs but a result of complications from stage 4 cancer. The 59-year-old, who died on Aprill 22, had no illegal narcotics in her system, the toxicology results obtained by Entertainment Tonight revealed.

After Moran's death, former "Happy Days" star Scott Baio, found himself in hot water for what many saw as a suggestion his co-star died from a heroin overdose. Later in an interview, Baio talked about Moran’s troubled life, where she struggled with alcohol abuse.

“I was asked ONLY about Erin's troubled past due to drug & alcohol abuse. I was still upset and said I felt that living that kind of a lifestyle will catch up with you and nothing good would come of it,” he said in a post explaining why he erroneously claimed Moran died from a heroin overdose. “THIS WAS BEFORE THE CAUSE OF DEATH WAS ANNOUNCED STATING STAGE 4 CANCER.”

Moran’s brother, Tony, slammed Baio for making the assumption about her cause of death.

"Well guys. Guess what? I was contacted by Scott Baio's wife. His wife! F---ing coward! I've never met her. I do know the scumbag piece of s--- Scott Baio though. He was a piece of s--- back then and still is. He had his wife contact me! Very apologetic and shit. Doesn't surprise me. It's too late you mother---ing pieces of s---! Go back under the rock you crawled out from under. There isn't one word I want to hear you speak. Makes me sick to my stomach," Tony wrote on Facebook.

Baio later clarified his comments saying: “Please stop assuming the worse in me. I'm a compassionate person. I'm very heartbroken over her passing, especially since it was cancer. ... I don't see people going after or attacking every network that said it was a drug overdose. I've openly stated my truths. I'm done.”

Moran was best known for her role as Joanie Cunningham on "Happy Days," which ran for 11 seasons. Moran's husband, Steven Fleischmann, also penned an open letter about his wife's last days and her cancer. "It got so bad, so fast," he wrote. "I fell asleep, woke up about a hour later, still holding her hand and she was gone. She was just gone."

Late last month, Moran's brother Tony said in an interview his sister was "penniless" and had been living a tragic life.

“Erin was a tortured soul who never recovered after Happy Days. Hollywood chewed her up and spat her out,” Tony said in the interview. He also said that his sister, who was suffering from throat cancer, kept her illness a secret from her five siblings
