DNA analysis leads to arrest in jogger attack
Aloha man faces several charges as officials seek additional victims
A 46-year-old Aloha man is being held in the Washington County Jail after DNA evidence linked him to a Dec. 27, 2012, attack of a woman jogging in Aloha.
Thomas Alan Davis is charged with kidnapping, attempted sex abuse and fourth-degree assault and is currently being held on $250,000 bail.
Washington County sheriff's detectives believe there may be additional sexual abuse victims of the man who have not come forward, said Sgt. Bob Ray, sheriff's office spokesman.
The Washington County Criminal Apprehension Team arrested Davis on Monday morning as a result of DNA located on the gloves of the jogger.
The woman was reportedly jogging along Southwest Farmington Road near 209th Avenue in Aloha the morning of Dec. 27, when a man approached her from behind. The suspect reportedly grabbed her and attempted to drag her into the bushes.
The woman broke free of his hold and ran for help, according to the sheriff's office. Deputies began a broad search for the unknown suspect, but were not able to locate him at that time.
Washington County violent crime detectives were called in to assist with the investigation.
"The victim reported that during the struggle, she grabbed the man's face, causing her fingers to enter his mouth," Ray said. "Washington County crime scene technicians gathered evidence while detectives searched for additional information.
"The woman's gloves were sent to the Oregon State Crime Lab for DNA analysis."
On June 10, sheriff's detectives received a report from the crime lab identifying Davis as a match from the DNA located on the gloves, Ray said. His DNA was on file from a 2009 criminal conviction.
On June 17, a Washington County grand jury indicted Davis on numerous charges. However, investigators were forced to wait until Davis returned from his job out of state to arrest him.
He was arrested without further incident on Monday.
Meanwhile, during an unrelated investigation by Beaverton police, Washington County detectives learned "Mr. Davis was responsible for leaving violent, sexually explicit notes on various random female's vehicles," Ray said. "These notes were left on vehicles while parked in shopping centers in Beaverton, Wilsonville and Sherwood."
This new information prompted detectives to seek the public's help in locating any additional victims.
"The Washington County violent crime detectives believe there may be additional victims of unreported crimes committed by Davis," Ray said. Anyone with information about this case is asked to call the Washington County Sheriff's Office at 503-846-2500.Add a comment
