David Karl Heitman, a 42-year-old Marine Corps veteran, was last confirmed in Columbia, Missouri, on April 19, 2016, when he spoke with his social worker and reportedly mentioned plans to go to a lake with a friend. By early June the social worker’s home visit found his residence empty, and a missing person report was filed with the Columbia Police Department on June 23, 2016. Heitman was described as having a shaved head, brown eyes, and distinctive tattoos, including a Superman-style H on his back, a black panther on his forearm, and USMC insignia.

In October 2016 a hunter found a duffle bag about two miles into the Mark Twain National Forest in Pulaski County, roughly 100 miles south of Columbia, containing clothing and identifying documents belonging to Heitman. A ground search of the rugged area followed but produced no further evidence. The sequence — a reported plan to go to a lake, an empty home weeks later, and personal items recovered far from Columbia — leaves the timeline and Heitman’s whereabouts unresolved.

If anyone knew Heitman’s routines, the friend he planned to visit, or saw him after April 19, 2016, please share information with the Columbia Police Department.
