HILLSBORO, Ore.- On May 1, 2020, a Washington County jury found Dale William Martineau guilty of two counts of second-degree robbery, two counts of menacing, second-degree theft and unauthorized use of a motor vehicle. On May 5, 2020, Judge Andrew Erwin sentenced Mr. Martineau to 105 months in prison. Deputy District Attorney Nadya Martin prosecuted the case against the defendant.
On August 22, 2016, the defendant approached a man outside his Tualatin, Oregon residence and asked him for a ride. The man went into his home to retrieve his keys but forgot that they were already inside his vehicle. Mr. Martineau then got into the vehicle and drove off. The owner tried to give chase but was unable to catch the defendant. The owner was able to help identify the defendant when police arrived.
A short time later, the defendant drove the stolen vehicle to a nearby Fred Meyer. The defendant entered the business and approached a cashier. The defendant repeatedly told the employee to open the register and demanded he give him cash from the register. He threatened to shoot the employee if he didn’t comply. The defendant lifted his shirt to show the victim what appeared to be a semi-automatic handgun tucked into his pants. The cashier handed over the cash and the defendant fled the area in the stolen vehicle. Tualatin Police responded to the call and eventually used surveillance footage to confirm Mr. Martineau’s role in the robbery.
On August 29, 2016, Mr. Martineau entered another Fred Meyer location in Beaverton, Oregon. He approached a customer service representative, displayed a handgun and demanded cash. The employee refused and walked away. The defendant approached two additional workers but was rebuffed by them as well. Video surveillance obtained by investigators clearly shows the defendant displaying what appeared to be a handgun during the incident.
As the investigations continued, detectives learned the defendant was in Yamhill County, Oregon. Detectives drove to the location and attempted to apprehend the suspect. Mr. Martineau refused to respond or exit the trailer for several hours before he eventually surrendered to authorities. The owner of the stolen truck was able to recover his vehicle.
The Washington County District Attorney’s Office would like to acknowledge the Tualatin Police Department, Beaverton Police Department, Newberg-Dundee Police Department and Oregon State Police for their work on this case.
In addition to his prison sentence, Judge Erwin also ordered the defendant pay $690 in restitution to his victims and undergo three years of post-prison supervision upon his release. Mr. Martineau will be transferred to the Oregon Department of Corrections to begin serving his sentence.
