Kronk, who discoverered the remains, repeated the same basic story that he had told police.[55] On Friday, October 24, 2008, a forensic report by Arpad Vass of the Oak Ridge National Laboratory judged that results from an air sampling procedure (called LIBS) performed in the trunk of Casey Anthony's car showed chemical compounds "consistent with a decompositional event" based on the presence of five key chemical compounds out of over 400 possible chemical compounds that Vass's research group considers typical of decomposition. Investigators stated that the trunk smelled strongly of human decomposition,[56] but human decomposition was not specified on the laboratory scale. The process has not been affirmed by a Daubert Test in the courts.[57] Vass's group also stated there was chloroform in the car trunk.[58]
