Summary based on the NamUs case record (MP4299) and 5 other sources
Karl Lee Larsen, a 44-year-old man from Paola, Kansas, was last seen on February 24, 2004. On the day of his disappearance, Larsen asked his mother to pick up his son from school, which was the last known contact anyone had with him. Karl was a single father and had full custody of his son. He was known to suffer from schizoaffective disorder, a mental health condition that required medication, but it is believed that he may have stopped taking his medication prior to his disappearance.

In late March 2004, about a month after he vanished, Karl’s tan 1992 Saturn was found abandoned behind a farmhouse in rural Linn County, an area where he often went duck hunting. The car was locked, and his keys and identification were found inside, but there was no sign of Karl. A receipt for a box of bullets was later discovered in his apartment, dated just before he disappeared, although no handgun was found.

There is speculation that Karl may have taken his own life, particularly given his mental health struggles and the fact that he had recently lost his job with the Paola Public Works Department. However, there is no concrete evidence to confirm this theory, and his case remains unsolved. Anyone with information is encouraged to contact local authorities.
