Federal prosecutors charged a Pennsylvania resident with kidnapping after he allegedly lured a woman he led to believe was his girlfriend to the Nevada desert, killed her and moved into her house, authorities say.

The Clark County Office of the Coroner/Medical Examiner Thursday officially identified the remains of Jaime Feden, according to Lincoln County Sheriff Kerry D. Lee.

Authorities had thought a DNA test would be necessary to identify the remains that were discovered outside Las Vegas on October 5, but dental records were able to reach a positive match, Lee said.

The family approached US 93 and pulled over for a bathroom break. One of them wandered away to use the bathroom in the desert area and came across Feden’s remains, authorities said.

Chapman told police he tied her to a signpost in the Nevada desert and suffocated her to death, according to the criminal complaint. He then posed as her on social media to communicate with her family after she was dead, police say.

John Chapman, 39, faces charges of kidnapping, obstructing administration of law, and criminal use of a communication facility in Pennsylvania, according to the complaint filed in Allegheny County.

At some point on or about September 25, Chapman convinced Feden to drive into the desert to participate in a “bondage themed photo shoot,” bound her hands and feet with zip ties, affixed her to a signpost and duct taped her mouth and nose until she died from suffocation, the complaint said. He then removed the tape, zip ties and her clothing and left her body, according to the complaint.

A preliminary hearing for Chapman was continued Thursday and rescheduled for December 5, according to court records. Bail has been denied and he remains in custody at Alleghany County Jail, records show.

CNN has not been able to identify an attorney for Chapman.

Chapman has not been charged with any crimes in Nevada, but Lee said Lincoln County sheriff’s deputies will soon travel to meet with authorities in Pennsylvania after meeting with the Lincoln County District Attorney’s Office.
