Yaron Segal, the Massachusetts Institute of Technology researcher, accused of flying to Colorado to have sex with underage girls, was found dead in his jail cell Friday.
Prison officials at FCI Englewood in Colorado said he was found alone in his cell and hanging from a homemade noose, according to reports.
The federal prison inmate tracker listed the 31-year-old as deceased.
FCI Englewood is a low-security prison in Littleton, Colo., according to the Federal Bureau of Prisons.
Federal authorities charged Segal for allegedly setting up a sexual encounter with a mother and her two underage daughters.
However, the mother Yhe thought he was talking with online was actually a federal agent.
Segal allegedly flew to Colorado late last month for the rendezvous with the mother. Federal authorities met him instead.
A federal complaint alleges that Segal, an Israeli citizen and Yale graduate, started chatting with the agent while both were in chat rooms named “childslavesex” and “childrapetorturebrutality.”
The agent, using an under cover persona, said she had two daughters, one under 16 years old and another under 12 years old.
“The suspect immediately turned the conversation to sex, and indicated that he wanted to have sexual intercourse with the UC persona and both of her children,” according to the federal complaint.
Segal was charged with travel with intent to engage in illicit sexual conduct and travel with intent to engage in a sexual act with a person under 12 years of age, according to court documents.
Segal's attorney, Rick Kornfeld, said his client planned to challenge the allegations and charges.
"God is in the details of the facts and I haven’t had the opportunity, nor has he, to review those yet," Kornfeld said earlier this month, shortly after his arrest.
Kornfeld also said that Segal had no prior criminal history and served in the Israel Defense Force.
