LYNNWOOD — Authorities in Montana have arrested a man wanted by Lynnwood police for allegedly draining his mother’s bank accounts after she was diagnosed with dementia.

Mark M. Peters, 59, has been taken into custody in Flathead County, Montana.

Jail records show he remained booked there Tuesday.

Lynnwood police were told Peters was arrested without incident, Cmdr. Sean Doty said.

“Our detectives are working on bringing him back to Snohomish County,” he said.

A call to the Flathead County Sheriff’s Office was not immediately returned.

Peters is charged here with first-degree theft, a felony. He’s been on the lam since skipping out on court in fall 2017. A governor’s warrant for extradition was issued in October 2018.

Washington’s Adult Protective Services contacted Lynnwood detectives in August 2016 about a woman in her 80s. She was living with advanced dementia in a local senior home, while her money apparently was being used for gas, movie rentals and a gym membership.

Prosecutors allege that Peters, her son, failed to make payments for her care. By late 2018, the mother was moved to another location as the investigation continued.

In addition, the Maui Police Department has a missing person investigation for the defendant’s father, Myron C. Peters, dating back to June 2016. The department previously declined to discuss the case.
