Summary based on the NamUs case record (MP35049) and 3 other sources
In the spring of 2016, a 42-year-old United States Marine Corps veteran named David Karl Heitman vanished from his home in Columbia, Missouri. The last confirmed contact with him was on April 19, 2016, when he spoke with his social worker. During that conversation, he reportedly mentioned plans to go to the lake with a friend. Concern grew when, over two months later, the social worker conducted a home visit in early June only to find Heitman's residence empty. A missing person report was officially filed with the Columbia Police Department on June 23, 2016. At the time of his disappearance, Heitman was described as having a shaved head, brown eyes, and several distinctive tattoos, including a Superman-style 'H' on his back, a black panther on his forearm, and USMC insignia.

The case took a perplexing turn several months later, in October 2016. A hunter, deep within the Mark Twain National Forest in Pulaski County, discovered a duffle bag containing clothing and identifying documents belonging to David Heitman. This discovery was made approximately 100 miles south of Columbia and about two miles into the forest from the nearest road. The finding prompted local authorities to conduct a ground search of the rugged, wooded area in hopes of finding further signs of the missing veteran. Despite their efforts, the search yielded no additional clues, and the trail went cold, leaving investigators and loved ones with more questions than answers.

The circumstances surrounding David Heitman's disappearance remain unclear. The initial report of him going to a lake, followed by the discovery of his personal belongings in a remote national forest far from his home, created a confusing timeline for law enforcement. As a veteran who had served as an aircraft ordnance technician in the Marine Corps, he was not without survival skills, yet the evidence left behind provided no clear indication of his fate or whereabouts. The overview of the case is one of a sudden and unexplained absence, a mysterious relocation of personal items, and a subsequent lack of any further evidence, leaving his case an unresolved and open investigation.
