A driver who was arrested after engaging authorities in a standoff early Thursday in Tualatin has been identified as a Crooked River Ranch man suspected in his mother's death, an official confirmed.

Gavin Smith-Brown, 29, is suspected in the homicide of 65-year-old Gayla Smith, according to the Oregon State Police. Smith was found dead Sunday at a home they shared, the agency said.

Authorities later asked for help finding Smith-Brown, saying he has ties to the Portland area and Las Vegas.

He was arrested before 6 a.m. Thursday after holing up in a car in a McDonald's restaurant parking lot at the corner of Southwest Boones Ferry and Tualatin-Sherwood roads, according to Tualatin police spokeswoman Jennifer Massey.

The incident unfolded after officers apparently tried to pull over what they thought was a stolen car just after 3 a.m., Massey said. The driver, apparently Smith-Brown, stopped at the McDonald's and refused to get out of the car. Tactical negotiators were called in, and Smith-Brown eventually complied with their commands.

KATU-TV reports authorities used a robot to remove a suspicious device from the car. The item was later detonated, according to the news station.
