Actor and rising star Angus Cloud shocked his doting fans when the actor died suddenly on July 31 of this year. An Alameda County Coroner’s Bureau has now confirmed the cause of death as acute intoxication, the result of taking a lethal mix of methamphetamine, fentanyl, cocaine and benzodiazepines.

Cloud is known for his role as drug dealer Fezco “Fez” O’Neill, starring opposite fellow Oakland native Zendaya in the hit HBO series Euphoria. The actor earned his break into fame as a waiter in Brooklyn, New York, where he was scouted for the role by a casting director of the show.

The 25-year-old, who has been open throughout his time in the spotlight about his battle with mental health, was found unresponsive in his family’s Oakland home in late July. Following his death, Cloud’s mother shared in a post on social media that she believed her son “did not intend to end his life.”

“I want you to know that although my son was in deep grief about his father’s untimely death from mesothelioma, his last day was a joyful one,” Lisa Cloud wrote in a post on Facebook. “He was reorganising his room and placing items around the house with intent to stay a while in the home he loved. He spoke of his intent to help provide for his sisters at college, and also help his mom emotionally and financially. He did not intend to end his life.”

Leading up to his tragic death, Cloud had been dealing with the loss of his father from mesothelioma, a type of cancer. He travelled to Ireland in the week before his own passing to bury his beloved father, with whom he shared a close bond.

Following news of his death, fellow co-stars and industry figureheads shared their sorrows about the actor’s loss of life online. Co-actor and friend Zendaya, with whom Cloud had also been a student at the Oakland School for the Arts, shared a heartfelt post on Instagram about the actor.

“I’m so grateful I got the chance to know him in this life, to call him a brother, to see his warm kind eyes and bright smile, or hear his infectious cackle of a laugh,” wrote Zendaya.

An online eulogy from the Cloud family read, “Angus was open about his battle with mental health and we hope that his passing can be a reminder to others that they are not alone and should not fight this on their own in silence."
