SAN DIEGO (KGTV) - The family of Kiera Bergman says a recent development in her murder case has left them frustrated and fearful.
The 19-year-old woman was missing for weeks before her body was discovered in the desert outside of Phoenix last year.
Bergman's boyfriend, Jon Clark, was charged in the murder; but this month, a judge lowered his bond from $1 million to $100,000.

"I fear for my family, I fear for her roommate and any other girls out there that he could have the opportunity to start manipulating," said Kiersten Bragg, Bergman's mother.
According to CBS 5 Phoenix, Clark's lawyers argued there's new evidence that might clear him in his trial. They also say that in original court paperwork, police detectives made comments that didn't add up.
If Clark does bail out, he'll have to wear an ankle monitor.

"I just yeah, I broke down and lost it, called my husband and let him know," said Bragg.
She's frustrated Clark could potential go home and be somewhat comfortable, while her daughter will never get that chance again.
Previous court documents reveal suspicious text messages and Wi-fi records as some of the evidence police used to arrest Clark. Documents also showed a history of domestic disputes.
