Karl Lee Larsen, 44, of Paola, Kansas, was last seen February 24, 2004. His final known contact was a request that his mother pick up his son from school; Larsen was a single father with full custody. He had schizoaffective disorder and required medication, and it is reported he may have stopped taking that medication before he vanished.

About a month later, in late March 2004, his tan 1992 Saturn was found locked and abandoned behind a farmhouse in rural Linn County, an area he frequented for duck hunting. The car contained his keys and identification, but there was no sign of Larsen. A receipt for a box of bullets dated shortly before his disappearance was later found in his apartment; no handgun was recovered. He had recently lost his job with the Paola Public Works Department, and there has been speculation about suicide, but no concrete evidence confirms that theory and the case remains unsolved.

Anyone who knew Karl, saw him in late February or March 2004, or has information about the car or the rural area where it was found is urged to contact local authorities.
