Jones' son, identified only as Cody, told KPHO the incident was out of-character for his mother.
"My mom has never, ever done anything like this," Cody said, according to KPHO. "This is the first thing I've ever heard of my mom doing something extreme like this. My mom's never been an aggressive person."
The news station reported Jones and Davis have been dating for the past six years. Court records obtained by KSAZ-TV showed Jones has lived in the home where she was arrested for a month.
A judge set Jones' bail at $15,000, according to KPNX. She's expected to appear Thursday in court for a status conference, KPHO reported.
