LAYTON — Davis County sheriff's deputies have arrested a man they said kidnapped and assaulted his estranged girlfriend.

A Woods Cross woman called police and said her boyfriend showed up at her apartment on Sunday, asking to talk about problems in their relationship. Deputies said the woman claimed that during a drive, her boyfriend said he would have her beaten up and her body dumped somewhere it couldn't be found for days.

According to a police report, when the woman tried to flee his vehicle, the 27-year-old man grabbed her.

"He then choked (the woman) until the point she became unconscious," Davis County sheriff's deputy J. Shuler wrote in a report.

Deputies said when the woman woke up, she said the boyfriendhad driven her to an area near Layton. She told police she tried to run, but the man tried to chase her. His car became stuck in a ditch, and they had to wait for help from his parents before she was taken home.

On Monday, Davis County prosecutors filed multiple charges against Michael Paul Montgomery, including second-degree felony kidnapping, aggravated assault, a third-degree felony and threats against life, a class B misdemeanor.
