PHOENIX — New developments have been released in the case of Jon Christopher Clark regarding the murder of Kiera Bergman.

In a status conference before Judge Jay Adelman, Clark was ordered to be released from custody with electronic monitoring until his trial. That trial was scheduled to begin on March 25 but has been postponed until April 6, 2020.

The judge also ordered that Silent Witness disclose the identity of an informant who called them saying they spotted Kiera Bergman at the Indigo Creek Apartments on Aug. 13, 2018, at 5:15 p.m., four days after she was reported missing.

Phoenix police and Maricopa County prosecutors were ordered to disclose all reports and contacts with the informant.

Bergman's disappearance garnered national attention for weeks in August 2018 after the 19-year-old went missing just hours after leaving work.

Roughly a month after her disappearance, her body was found near State Route 85 in Buckeye. Police arrested her ex-boyfriend, Jon Christopher Clark, and charged him with Kiera's murder.

No murder weapon was ever discovered, and her cause of death was undetermined.

Jon Christopher Clark is currently the only person charged with Bergman's murder.

Detectives never found DNA on Bergman's remains or at the crime scene. They were not even able to determine the cause of death.

Detectives still made the arrest, writing in court documents that Clark was a physically abusive and manipulative boyfriend.

They also say he was the last one to see Bergman alive, and they say her cell phone was turned on days after she was last seen, and it connected to the same wireless internet as Clark's phone.

Police believe the boyfriend continued using her phone, but it was never found.
