The alleged attack happened on February 7, when Rosario invited the "complete stranger" over to her apartment at 1 AM after connecting with him on the app, they said.
But shortly after he arrived, three men burst into the home with guns and began pistol-whipping the victim; the four then stripped him and put him in a bathtub, before pouring "flammable substances on him, and burned him with a flame," the criminal complaint claims. It says they also stabbed him multiple times in back, legs and body.
"After multiple hours of torture," he was moved from the Marble Hill Avenue address to a different location where they then called his family to demand a ransom, Assistant District Attorney Andrew Kluger said at Rosario's arraignment on Thursday.
According to Kluger, they FaceTimed the victim's brother, demanding cash as they continued to torture him with the knife.
"Give us one hundred thousand dollars or we will kill him," they threatened, per the court docs.
Police were able to track down the alleged kidnappers to a location in Queens, where they surrounded a parked van. Inside they said they found Javier Vargas, armed with a knife.
