Prosectors in the Casey Anthony murder trial wish to utilize an air sample taken from Casey's car to prove her as the murderer of Caylee Anthony. However, defense attorney Jose Baez calls it "junk science", refusing to use it as evidence in the case.
Casey Anthony: Human Decomposition Odor Analysis
The prosecutors in the Casey Anthony trial are hoping to use human decomposition odor analysis to prove that Caylee's body was once stored in Casey's car. In this video from ABCs Good Morning America, both the defense and the prosecutor's sides regarding such evidence are observed.
Gas Chromatography is a method used to separate volatile compounds. This method was used in Dr. Arpad Vass' study regarding air samples from a decomposing human body. Dr. Vass used GC when he was given a sample of the carpet in Casey's car where Caylee's body may have been before it was...
Groundbreaking Science- Uncovering The Evidence
Dr. Arpad Vass, an air sample expert testifying in the Casey Anthony trial, found that human decomposition can release a variety of vapors, some of which cadaver dogs can smell. In his 2004 study, Vass hopes to create a database for "decomposition odor analysis".
Odor Analysis of Decomposing Buried Human Remains
Dr. Arpad Vass and other researchers composed a study analyzing the vapors released by a decomposing human body. The scientists used air samples which helped reveal eight classes of chemicals which are associated with human decomposition, proving it to be a reliable source of evidence. Below...
Forensic Biology Laboratory Report
In this forensic lab report to the defense attorney, Jose Baez, Dr. Kenneth G. Furton, Dr. Timothy E. Huntington, and Dr. Barry K. Logan have indicated that the utilization of odor analysis in this case is entirely unreliable in that there is not enough information to support the study done...
Criminal Trial - Admissible Evidence
In criminal trials, finding and presenting the right evidence is somewhat difficult. Apart from the Casey Anthony trial where air sampled evidence has been presented, criminal trials are specific with their evidence.
The Casey Anthony trial has just employed the use of odor analysis, or in other words, air sampled evidence. However, criminal trials are usually subjected to other forms of evidence.
DNA profiling is one of the most widely used forms of evidence in criminal trials. It is a recent form of analysis which identifies individuals by their DNA. DNA forensics is very different from odor analysis.
