Michael Sigman, works for the UCF, University Central Florida. On 21 July 2008 he received a call from LE asking if he could contact Mr. Striker about air samples from the death mobile.
He gave the sepal on how the gas chromatograph mass spectrometer works.
He went over to the car with his associate Doug Clark. Seems to find components in gasoline in the air samples that he took out of the car. He found organic components also in the air. He did not know that the trunk liner was removed from the car 4 days earlier.
He did a 7-1/2 hour sample testing in the trunk, and he found gasoline in the fibers after he took the second testing, chloroform was also found. He did not do an quantitative analysis on the fibers. He found traces of gasoline, chloroform and other chemicals found in trunk. He said that the results could have come from human decomposition……………………
Susan Mears verified the red bag and the gatorade bottle were 7 inches from the skull.
Michael Rickenbach is up again. He tested the steering wheel cover and the car seat cuttings, no traces of chloroform on them, but if the chloroform had moved inside the actual car, Casey would be dead right now. He talked about the doll and chloroform was low on the doll and got a similar doll and the doll had low traces of chloroform. In the gatorade bottle testosterone and traces of chloroform was found.
Karen Lowe was on the stand dealing with the hair and other evidence. [Remember the defense saying she wasn't an expert?] The clothes from Casey’s closet had no hairs that have decomposition on them, but hairs were found on the clothes. No decomp hair on the trash box from the car. No hairs with decomp on the paper towel or trash she tested. No hairs on the trunk liner piece she tested. Trash had no apparent hair with decomposition on it. The vacuum debris was not tested immediately when she received them, but later on.
The unidentified hair which was Q107 and tested against the CSI team that was at the scene searching for bones.
The hair in the trunk was identified to have decomp. You don’t know from June 16-July 15 where Casey was living. she did not know!
She did 9 separate reports in this case. BUT only found 1 hair with decomp from the trunk.
