A New York man has been charged with sexually abusing a 15-year-old boy whose body was found on a New Rochelle sidewalk earlier this month.

Hugo Horacio Perez-Gabriel, 32, was initially charged with concealing a human corpse in the death of Jonson Temaj, WCBS reports.

A new complaint against him says that Perez-Gabriel requested and received sexual material from the boy via WhatsApp, according to the Westchester County District Attorney’s Office.

“The allegations in this complaint are extremely disturbing. The fact that this same defendant was previously charged in connection with the dumping of a 15-year-old boy’s corpse makes this case all the more horrific,” Westchester County District Attorney Susan Cacace said in a statement. “My office is working around the clock to find out what happened to this boy, and I am committed to delivering justice to his family.”

The boy’s body was found near Charles Street and Washington Avenue in New Rochelle on February 6. A 16-year-old was also arrested in connection with the death.

The DA’s office said the new charges are two counts each of use of a child in a sexual performance, disseminating indecent material to minors, and possessing an obscene sexual performance by a child.

The medical examiner has not yet determined the cause of Tamaj’s death, and no one has been charged directly with the death.
