Miami Beach cops are investigating the death of an aspiring model who suffered a fatal overdose of a date-rape drug hours after she left the apartment of notorious “King of All Pimps” Jason Itzler and his roomie, The Post has learned.
Revelations of the probe — and a private investigation by the family of the dead woman— come as Itzler, 44, is locked up in a Manhattan jail on unrelated charges of promoting prostitution and drug sales.
The woman, Julia Sumnicht, a 21-year-old Wisconsin college student, had been visiting Miami Beach, Fla., in March 2010 in hopes of breaking into the world of fashion modeling.
A year before, during her first visit to the city, she had met Itzler’s roommate, Hungarian photographer Zoltan Prepszent, the family’s investigators say.
In their report to the family, the private investigators listed a chronology of Sumnicht’s last morning alive, March 15, 2010.
The PIs — Walter Philbrick and Chris Catania of the C3 Detective Agency in Oshkosh, Wis. — wrote that Sumnicht exchanged text messages with Prepszent and arranged to go with him early that morning to the SET nightclub.
Citing text messages, surveillance camera footage and other evidence, the private investigators said Sumnicht and Prepszent spent time at the club, returned for two hours to the Flamingo Towers apartment where he lived with Itzler and left together again.
Julia then went to an apartment building where she was staying as the guest of another photographer.
That other photographer later told another model that Sumnicht had been “drunk” when she came home and went to bed, despite an autopsy report that showed only a minute trace of alcohol in her urine, investigators said.
When he returned home later in the afternoon, the other fotog found Sumnicht dead in bed.
An autopsy report, obtained by The Post, showed she had died from ingesting the daterape drug GHB.
Based on a number of factors —including her behavior before and after going to the Flamingo Towers and the amount of time it takes for the drug to affect one’s system—the investigators concluded that she ingested it while in the apartment that Prepszent shared with Itzler, according to their report, which was provided to The Post.
Itzler, in a jailhouse interview with The Post, admitted to taking GHB himself that night after Sumnicht came to his apartment with Prepszent.
It wasn’t clear how or exactly when Sumnicht ingested it.
“I almost died that night,” Itzler said of the effect the GHB had on him. “Zoltan [later] changed all the decorating of the apartment. He knew that I threw up all over the apartment. I vomited GHB residue all over.”
Itzler said Prepszent retained a lawyer and hired another for Itzler after Sumnicht’s death. Prepszent did not respond to requests for comment.
A Miami Beach police spokesman declined comment, citing the ongoing investigation.
