They will never report such incidents.
For such an incident to be reported,
Somebody has to call 911 or the MP desk sergeant. The CQ notes initial details in his log.
The commander has to be notified so he can report it up the chain of command.
CID will be called in probably by the battalion commander.
If it involves a `protected class’ (faggies or trannies) the IG will get involved and the family members will no doubt request their Congressthing to investigate. The post commander & his protocol officer will soon be up to their buttplate in VIPs demanding answers.
Very messy indeed and all this will happen unless the body is emplaced somewhere other than inside the barracks. A division-sized installation has training areas, ranges, & bivouac sites with trails that have been there for generations, with soil, sand, or clay that is regularly churned during convoys or tracked vehicle movement.
Since disappearance does not always indicate death, the potential for a case to grow cold is considerable.
