Louis Steven Kathmann, 33, was last seen in July 2012 in Poplarville, Mississippi. He had driven from his home on Lavelle Ladner Road in Pearl River County to a friend’s house on Holden Road, and at some point during the visit left the residence on foot, leaving his vehicle behind. Friends and family have not heard from him since that day.

Kathmann had been disabled after a serious car accident and was known to struggle with an addiction to prescription painkillers. The Pearl River County Sheriff’s Department conducted grid searches and used K-9 units in the area where he was last seen, and investigators interviewed numerous friends, family and acquaintances. Authorities have considered that he might have been picked up by a passing vehicle or simply continued walking; foul play or an accident has not been ruled out. He was known to frequent the Bogalusa area, the Mississippi Gulf Coast, and may have had contacts in Jones and Forrest counties.

The decision to walk away from his friend’s house while leaving his car behind remains a central, unexplained detail. Anyone with information about Louis Kathmann, his whereabouts in July 2012, or contacts he may have had in the areas mentioned is asked to come forward.
