"Czar does both narcotics detection and all aspects of criminal apprehension. Czar can also track lost children, and works with the SWAT team."
Czar sounds like a very smart dog!
Note that he's not trained to detect cadaverine AND live human scent. He can track either a live human scent trail or detect the presence of narcotics. Sounds like he's also used as a general police dog to help contain a suspect. I also notice he is not an "FBI dog." He works for a small PD in Minnesota.
Now...back to Isa's case specifically. Two dogs were brought in. We were told what their specialty was for each. Which dog (if either one) detected narcotics? If neither did, was a 3rd dog brought in? I have heard nothing except for 2 dogs brought into THIS case. Were narcotics or the scent of narcotics found in either the home or any of the Celis vehicles?
