OAKLAND, Calif. (KRON) — Authorities have released the cause of death for actor Angus Cloud.

The “Euphoria” star died on July 31 inside his family’s home in Oakland, California. Angus’ death was investigated by the Alameda County Sheriff’s Office as a possible overdose, and his cause of death was confirmed this week by a coroner.

Angus died from acute intoxication due to combined effects of methamphetamine, cocaine, fentanyl and benzodiazepine, the sheriff’s office told News 2’s sister station, KRON, on Thursday. He was 25.

The rising young actor was grieving his father’s death in July, and he had recently returned to the Bay Area after burying his father in Ireland. Angus’ mother quickly dismissed rumors that her son’s death was a suicide, saying that his last day was “joyful.”

“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. She said he spent the day reorganizing his home and talking about how he wanted to take care of his sisters.

Angus put his head on his desk, which was filled with art projects he was working on, and fell asleep, his mother said. He never woke up.

“He did not intend to end his life,” Lisa said, adding that she was not aware if her son took any substances.

Angus was memorialized in Oakland by an artist who painted a large mural on a building on East 19th Street and Park Avenue. Oakland residents laid flowers and candles beside the mural honoring the actor.
