A MAN took his 4-foot special needs girlfriend to the Nevada desert and tricked her into thinking they would do an S&M photo shoot, but tied her to a signpost and watched her die, according to a criminal complain.
John Chapman, 40, will be formally charged with kidnapping that resulted in the death of Jamie Rae Feden, 33, who was dead, naked and bound at a signpost.
Chapman was initially arrested a month after the body of the 75-pound woman was found on October 5 just outside Las Vegas.
He has now allegedly admitted to killing Jamie for her money, according to the complaint.
Chapman will be formally charged next month, the Pittsburgh Post-Gazette reports.
If convicted, he faces life in prison.
Jamie suffered from VATER syndrome, which is a series of birth defects that affect several parts of the body and caused her short height.
Chapman had been living in Pennsylvania, with a wife named Maureen he had married almost a year before he was arrested.
Maureen claimed she had no idea Chapman was dating Jamie until he called from the police department and confessed to her.
Authorities said Chapman drove Jamie from Bethel Park, Pennsylvania to Las Vegas in mid-September.
They said he took her on vacation and to go house hunting.
According to a court affidavit signed by FBI Special Agent Jesse Laramee: "However, Chapman had planned to kill (Feden) before they left Pennsylvania and he had a kill kit ready before their departure for Nevada."
