Bat Handle
Why M-Vac

Bat Handle

The crime scene is a mess.  It looks like a close encounter shotgun killing, but on further inspection it was extreme blunt force trauma.  A softball bat appears to be missing from a gear bag near the front door.  The suspected weapon fits the crime scene, but it can't be found.

 Bat Handle

A search is commenced.  A nearby retention pond is searched by divers.  The bat is found, but the situation is complicated.  The bat has been in the water for at least 12 hours.  It is the middle of the hot season and the water is warm.  The grip is textured and the victim's wounds would suggest that it was gripped tightly.  The decision is made to sample the handle with the M-Vac.  The results included two full profiles, one was the owner of the bat who was the victim and the other belonged to the perpetrator.
