Michael John Delaney, 35, was last seen in the early morning hours of October 27, 1999, after being released from the Pierce County Jail in Tacoma, Washington, following a traffic violation. The exact date he actually went missing is uncertain; his family did not report him missing until early February 2001.

Delaney is described as a white male with brown hair and blue eyes, sometimes wearing a mustache and goatee. In April 2000 his 1982 Datsun pickup truck was found parked in the 1300 block of South J Street in Tacoma, near his home, but the recovery produced no new leads. Authorities consider the disappearance suspicious and suspect foul play. Family members say Michael had recently been in a heated argument with another man, though no connection to his disappearance has been established.

Anyone who knew Michael, saw that Datsun in late 1999 or early 2000, or has information about the argument is asked to come forward.
