Comedian Fuquan Johnson and two others died after allegedly overdosing on cocaine laced with fentanyl at a Venice house on Saturday, while comic and model Kate Quigley was in serious condition.

The 43-year-old Johnson, who had just performed at the Laugh Factory last week, was one of three persons who died early Saturday morning inside a residence along the Venice Beach canals, according to the Los Angeles Police Department. Johnson was a stand-up comedian and a writer for “Comedy Parlour Live” in Los Angeles.

Natalie Williamson, 33, of Los Angeles, and Enrico Colangeli, 48, of Medford, Massachusetts, were the other two victims, according to the Los Angeles County coroners’ office.

The cause of death has not been determined, although preliminary indications indicate that all three died from an overdose.

The victims, including 39-year-old comedian and model Kate Quigley, took cocaine laced with fentanyl, according to TMZ, which broke the news first.

When firefighters flooded the 200 block of Carroll Canal soon after midnight on Saturday, they discovered Quigley, a local resident, in serious condition and transported her to the hospital. The others had already passed away.

People in the normally peaceful neighborhood were jolted awake by the late-night reaction.

While Quigley is expected to recover, Ron G., the show’s presenter, told CBSLA that he will observe a minute of silence in her honor and to pray for her.
