Clark Gable‘s grandson’s cause of death has been revealed.

Clark James Gable, who was found dead at 30 on Feb. 22, died of an accidental fentanyl overdose, according to multiple reports.

According to a spokesperson for the Dallas County Southwestern Institute of Forensic Science, Gable died from “the combined effects of fentanyl, oxycodone and alprazolam,” reported the New York Daily News.

“The manner of death is an accident,” added the spokesperson.

TMZ went on to report his time of death is listed as 9:11 a.m.

Fentanyl is the same opiate that was the cause of Mac Miller‘s accidental overdose in September 2017, as well as Tom Petty‘s death on Oct. 2, 2017 and Prince‘s death on April 21, 2016. The extremely powerful, synthetic opiate is 80 times as potent as morphine and hundreds of times more potent than heroin.

The Dallas County Southwestern Institute of Forensic Science did not immediately respond to PEOPLE’s request for comment.

The actor, was found unresponsive on the morning of Feb. 22, his sister Kayley Gable previously shared on Facebook. His death was also confirmed to Variety. The outlet reported he died at the Texas Health Presbyterian Hospital in Dallas.

“My brother was found unresponsive this morning by his fiancé and didn’t wake up,” she wrote. “I LOVE YOU CLARKIE I’m so sorry we couldn’t save you my heart is broken and shattered RIP.”

His mother, Tracy Yarro Scheff, also confirmed the news on Instagram, writing, “It’s is with an extremely heavy heart we say goodbye to my beautiful son Clark.”

“He passed this morning. I will always be next to you my beautiful son. Mom,” she added.

Gable was the host of the reality TV series Cheaters, which exposes infidelity within relationships. He was filming a crime drama titled Sunset Dawn shortly before his death, according to Variety.

His father is John Gable II, the son of actress Kay Williams and the Hollywood icon who is best known for his role as Rhett Butler in the 1939 epic drama Gone with the Wind, who died in 1960 from an arterial blood clot after suffering a heart attack.

The Cheaters host frequently shared photos of his famous grandfather on Instagram.

In July, he shared the icon’s army photo, writing, “Thinking about my grandfather Maj. Clark Gable (US Army Air Force 1942-1944) before #independenceday #july4th#clarkgable #usa.”
