PORTLAND, Ore. (KOIN) — Detectives say there may be more victims after they arrested an Aloha man for sex abuse.

The Marion County Sheriff’s Office reports that Thomas Davis, 46, attacked a female jogger in December 2012. The woman was jogging near Southwest Farmington Road and 209th Avenue in Aloha, Ore.

Detectives said he approached the woman from behind, grabbed her — and tried to drag her into the bushes.

She broke free and ran for help.

Davis was arrested earlier this past week after deputies say they linked him to the crime through DNA evidence left on the victim’s glove. Her gloves were analyzed by the Oregon State Crime Lab after the victim reported that her gloved fingers touched inside his mouth during the struggle.

The 46-year-old also stands accused of leaving sexually explicit notes on random women’s cars at shopping centers in Beaverton, Wilsonville and Sherwood. The sheriff’s office reported Beaverton police discovered this in “an unrelated investigation.”

He has since been taken to the Washington County Jail. Davis now faces charges of Kidnapping, Attempted Sex Abuse and Fourth Degree Assault and is being held on $250,000 bail.

“The Washington County Violent Crime Detectives believe there may be additional victims of unreported crimes committed by Davis,” according to a news release distributed Tuesday. “Detectives are seeking the public’s help regarding this case.”

Anyone with information can call the Washington County Sheriff’s Office at 503.846-2500.
