A 26-year-old Army reservist scheduled to report for annual training vanished Jan. 26 near the Clackamas Town Center.
Will Naugle has been serving a combat medic and was connected to the Army reserves at Camp Whithycombe in Clackamas.
Naugle's family is offering a $1,000 reward for information that helps authorities locate him. The man's family said he was raised in Portland but recently moved to Clackamas in order to live with a friend.
His disappearance first came to light when a sergeant and major knocked on his door trying to find him. He was scheduled to report on Jan. 21, but his family said he got the dates mixed up and left on Jan. 26.
That was the last day he was seen, around 3 p.m.
Naugle's family says it's not like him to go missing, and they're extremely worried.
"He got ready, left in uniform, walked out his front door, told his roommate, 'I'm late, I got to go,' and no one's seen him since," said James Naugle, the missing reservist's brother.
The Naugle family said Naugle's car, a white Honda Civic, was located on the street near the mall. They're not sure if the window was already broken, but Will Naugle's hat with his last name on it is clearly visible.
Family members told KOIN 6 News that Naugle served six years in the National Guard and toured in Afghanistan. They said he was always proud to be part of the military.
"I am really worried, scared and very puzzled," his sister, Julie Terry, told KOIN 6 News. "Just baffled on how somebody can be dressed, ready to go to training and walk out their front door and disappear."
She said he was very excited about his new reserve unit "so I don't see why he wouldn't be there."
Family members have been handing out missing fliers since his disappearance hoping to find someone with knowledge of Naugle's location. The Clackamas County Sheriff's Office said as of Tuesday it has no leads.
