The cause of comedian Ken Flores’ unexpected death has been revealed seven months after he died at just 28.

A report from the Los Angeles County Medical Examiner determined that Flores died in January 2025 of a drug overdose.

The medical examiner determined that the rising stand-up star’s death was accidental and was a result of cocaine toxicity, according to TMZ.

Flores was also suffering from congestive heart failure at the time, which the report determined had contributed to his death.

The medical examiner concluded that the only substance present in Flores’ body at the time of his death was cocaine. Tests showed negative results for other potentially harmful substances such as alcohol, fentanyl, meth, opiates, or other drugs.

It was previously reported that Flores had been concerned about his heart condition.

In January, TMZ reported that Flores had been making an effort to improve his health shortly before his death.

As explained by Cleveland Clinic, ‘Congestive heart failure is a chronic condition that occurs when your heart can’t pump blood effectively enough to provide your body with a sufficient supply. Over time, blood and fluids accumulate in your lungs and legs.’

Sources close to the late comedian and law enforcement officials indicate that Flores sought medical assistance several times at the hospital during the past two years.

Flores had also been losing weight and attempting to improve his health.

Moreover, it was reported by TMZ that oxygen tanks were found at his residence, and Flores had been using oxygen. Home oxygen therapy is a treatment option for congestive heart failure, according to Dignity Health.

Ken suffered cardiac arrest and was discovered in his home by a friend. The friend called 911 and administered CPR while waiting for paramedics, as reported by TMZ.

Flores was pronounced dead at the scene.

Insiders added that no drugs were found and foul play was not suspected.

While congestive heart failure also contributed to Flores’ death, no other substances besides cocaine were found in his system; Flores is pictured August 2024.

An autopsy was performed by the Los Angeles County Medical Examiner’s Officer, and the cause and manner of death were to be announced following the return of a toxicology test, TMZ added. 

Flores’ family announced his tragic passing in January in a statement posted to his Instagram.

‘It is with great sadness that we confirm the untimely passing of our friend, brother, and son, Kenyi Flores,’ the family posted on his Instagram account.

‘Please respect our privacy at this time as we are all shocked and devastated by this loss.’

Shortly before his death, Flores revealed via X that he was making an attempt at being booze-free for his 2025 tour.

‘So I started my tour a couple weeks ago and I’m proud to say I’ve done every single show – five in Portland, one in Albuquerque, and four in Atlanta – without a single drop of alcohol,’ the Chicago-based funnyman tweeted.

‘Nervous for Phoenix next weekend but I think I got it. I’m not sober just wanna chill a bit.’

Indeed, Ken was scheduled to perform shortly after his death at Desert Ridge Improv in Phoenix, Arizona.
