The Phoenix Police Department is seeking to charge Jon-Christopher Clark, 23, for the first-degree murder of 19-year-old Kiera Bergman, the improper removal of a body and evidence tampering.

Clark was already in custody for unrelated crimes. While investigating Bergman’s disappearance, police found evidence of identity theft and forgery in his car and subsequently arrested him, Phoenix police Sgt. Vincent Lewis said.

“It was not until today that investigators have probable cause to charge him with first-degree murder,” he said.

The reason it took so long to charge Clark was that investigators had to wait for results of some evidence and for certain parts of the investigation to be completed, Lewis said.

Bergman, who was originally from El Cajon, was last seen alive Aug. 4 leaving her home without her car or money. Police deemed her disappearance suspicious about a month after she disappeared. She moved to Phoenix in March to be with her boyfriend and Bergman’s family had been wary of Clark since her disappearance.

Bergman’s body was found Sept. 3 by the Maricopa County Sheriff’s Office off state Route 85 and Hazen Road. The condition of the body was not disclosed.

“We are confident that harm befell her on (Aug. 4). She was last seen alive at her residence,” Lewis said. “The questions we don’t have answers right now that we are still waiting for — and hopefully the medical examiner can answer — are causee and manner of death.”

Route 85, where Bergman’s body was found, is a popular route to and from San Diego from the Phoenix area, Lewis said. It connects Interstates 10 and 8.
