ORLANDO --
Cadaver dogs are expected to be the hot topic during day two of a battle over which scientific evidence should be allowed in Casey Anthony's trial.
Casey's attorneys have claimed the police dogs were not reliable, and their handlers may have tipped them off in the search for Casey's 2-year-old daughter, Caylee.
Shortly after Caylee disappeared in 2008, two dogs trained to detect decomposing bodies searched the Anthony family's backyard, as well as Casey's car.
Detectives said the dogs alerted them like they found something, but the defense questioned how they could know for sure that was really what they were signaling.
Caylee's remains were found in a wooded area near her family's home six months after she first disappeared.
Prosecutors want to prove her body was initially in the trunk of her mother's car, where one dog stopped and sat down, signaling an alert.
Casey's lawyers, however, said that's not real science.
