Air Tested
Meanwhile, Local 6 has learned that a lab affiliated with the University of Tennessee may be using a new type of technology to test air samples taken from the car of Caylee's mother, Casey Anthony.
Cadaver dogs led detectives to believe there were signs of decomposition in the trunk of Casey Anthony's vehicle and hit on two spots in the child's grandparents home early in the search for the missing girl.
The lab apparently testing the air samples, called The Body Farm, is run by the school's anthropology department.
A researcher at The Body Farm has developed an artificial nose of sorts that can sniff out evidence of human decomposition and decay.
It works by recognizing compounds found in the air where decomposition occurs.
Detectives won't confirm where the samples were transported to, but they said the air samples are being tested for decomposition.
