Casey Anthony Trial: Forensic Evidence Questioned for Validity

Casey Anthony's defense lawyers are questioning the validity of the forensic evidence that suggests Anthony killed her two-year-old daughter, Caylee.

Prosecutors attempted to prove that Anthony hid her daughter’s body body in her car’s trunk based on decomposition odor analysis, the study of chemicals released when a body decomposes. Dr. Arpad Vass, a scientist at the Oak Ridge National Laboratory, testified early in the trial that the presence of certain chemicals proves that there was a decomposing body in the trunk of the car.

Some experts questioned the validity of Dr. Arpad’s methods and whether this can be of valuable use in court. Dr. Kenneth Furton, studying the chemistry of human decomposition, directly contested Vass's techniques. Furton said, "It's my expert opinion that there's currently no instrumental method that has been scientifically validated to the level that it could be used to identify the presence or absence of human decomposition."
