Dog handler:
On 17th I was advised there was a vehicle to sweep - possibility of human remains, cadaver odor. I responded, spoke to some techs. I asked them to move vehicle to outside bays. I deployed the canine, gave him command to locate odor of cadaver. Worked him in counter-clock method - he alerted to the vehicle. He was already alerting, but he wasn't giving a final so I had them ventilate. Dog alerted on trunk - jumped up, got in, gave me a final alert at the back fender in the trunk.

I also responded to residence of grandparents. I deployed dog in back yard area. There was an indention George didn’t recognize – I deployed dog on whole back yard, he alerted in the southeast corner over play area. Continued to work then took dog out. Called another cadaver dog. Had her come in for secondary search. Told handler that there were three areas, but that’s all I told her. Her dog alerted the same spots my dog did.

So it was one dog that hit on the trunk, then two dogs that hit on 3 spots in the yard. I watched the bond hearing live, and I have tried to correct the misinformation when I see it.
I hope this helps clear things up!
