"BCA agents first sweep a scene for any obvious evidence, and then we send in K-9 Sota," Munkelwitz said.
But a human's five senses during those sweeps for evidence can fail to find what a dog's nose can, Evans said.
"Years ago, when electronic evidence was becoming more prevalent, they were in very large computers," he said.
"We knew where they were. (But) as we all transitioned to all of us having a smartphone (and) all of us having evidence that is this small that is inserted into a phone, criminals are very well adept. They know we are looking for this evidence.
"This dog is really going to take us years forward," Evans said, "because her nose is much better, obviously, than any of ours."
The BCA received Sota thanks to the nonprofit Operation Underground Railroad, a nonprofit that fights sex trafficking.
The California-based organization paid about $15,000 to buy and train her. The BCA covers the bills for her kennel, food and work equipment.
