K9 handler Jason Forgey testified that Gerus, a German Shepherd cadaver dog certified in 2005, indicated a high alert of human decomposition in the trunk of Casey's car, saying the police dog has had real-world searches numbering "over three thousand by now". During cross-examination, Baez argued that the dog's search records were "hearsay".[80] Sgt. Kristin Brewer also testified that her K9 partner, Bones, signaled decomposition in the backyard during a search in July 2008. However, neither K9 partner was able to detect decomposition during a second visit to the Anthony home.
