The Los Angeles County Coroner's Office has revealed the cause of The Goldbergs actor Jackson Odell's death. Per People, the 20-year-old suffered from "acute heroin and cocaine toxicity." Odell was found unresponsive in a sober living home in suburban Los Angeles on June 8. He reportedly had struggled with heroin addiction, though a recent drug test had come back clean. In a statement obtained by E! Online, Odell's family said the young actor was feeling upbeat about his future just before his death. "We were with him only days before he died," the statement reads. "He was happy. He sang one of his songs for us and luckily we recorded it. He was in a good place and so optimistic not only about his sobriety but his future. He wanted to live and to share the music that poured out of him." (More jackson odell stories.)
