murder dogs

Train the smartest of the highly trained dogs to use olfactory interrogation on a murder scene. The dog would be trying to remember the freshest scents of people that have had a presence in the space. The dog can then indicate on people questioned, to show those involved with the scene.

Of course, the case will have to be one suitable. A stabbing, fight or close quarter murder rather than a time delayed poisoning or distance shot. And the dogs will have to be trained to wear white forensic onesies with ear holes, rubber grip booties and contamination elimination muzzles that don't hinder olfactory referencing.

The dogs might even be given movement training to stay out of common human motion pathways and zig-zag the scene in unconventional ways to recover scents. If they are really smart, they may even indicate stuff that doesn't quite fit in an olfactory dimensional scene sense. A dog view photo of this indication will be another piece in the puzzle for human detective interpretation.

Dogs so good, an owner is identified when a dog did it.
