INITIAL POST: Oregon troopers found the car of a missing Federal Way man Tuesday afternoon at an Interstate 5 rest stop north of Albany, the agency said.
Adam Standridge, 32, was last seen Sunday at his Federal Way home, about 8 p.m. in the 1000 block of South 316th Street.
His 2012 Dodge Avenger was found abandoned Tuesday at the Santiam Rest Area in Oregon, first noticed by an employee there about 8 a.m.
Troopers searched the rest stop and the bank of the Santiam River, but did not find any sign of Standridge, the Oregon State Police said.
Standridge's family said he did not show up for a job he was supposed to start Monday, which they said is very unusual for him.
