PORTLAND, Ore. (KOIN 6) — An employee for United Airlines called his boss on July 2, 1999 and requested the night off for a “personal emergency.” The man has never been seen or heard from since, according to police.

The disappearance of Mark Jeffrey Dribin remains a top priority for members of the Portland Police Bureau Cold Case Homicide Unit.

When Dribin called his employer 15 years ago, he was scheduled to work the night shift at Portland International Airport, police said.

The 42-year-old man was described by friends and co-workers as “responsible” and was not known to miss shifts or to disappear for any amount of time.

Police said Dribin stayed in close contact with his family, and since his disappearance, no one has heard from him.

Investigators have searched Dribin’s residence. which was in the 3600 block of Northeast 137th Avenue. They found numerous items missing, including his vehicle, police said.

About two weeks later, the vehicle was eventually found in an area that investigators do not believe Dribin normally traveled. Citing the ongoing investigation, police declined to release information about where the vehicle was found or by whom.

“Based upon Mr. Dribin’s extended absence, his sterling work record and the lack of contact with his family, detectives were concerned for his safety,” police said.

Detectives have not said what was found at his home in Northeast Portland, but said based on the physical evidence they believe Dribin is dead.

Anyone with information on the case is asked to call CrimeStoppers at 503.823.HELP.
