Casey Anthony: Chemist Can’t Conclude There Were Human Remains in Trunk

It appears that a chemist who collected and tested air samples from the trunk of Casey Anthony’s car said that he couldn’t say for sure there was ever a body inside of it. His statements that conflict with prosecutors’ experts.

From Reuters:

“Based on our data, I cannot say there were human remains in that trunk,” said Michael Sigman, a chemistry professor at the University of Central Florida.

Sigman said he first collected two samples of air from the car trunk on July 21, 2008, at the Orange County Sheriff’s garage.

Sigman, a former colleague of prosecution witness Arpad Vass at the Oak Ridge National Laboratory, was recommended by Vass to do the collecting.

He left the bags of air with the Sheriff’s Office — one for delivery to Vass, the other one to be brought to Sigman at the National Center for Forensic Science lab, where he is the assistant director for physical evidence.

Sigman ultimately tested three separate collections of air from the trunk. The first, taken by extracting air in a syringe, showed weak organic compounds comparable to gasoline, he said. He then collected samples from the trunk using more sensitive methods.

    Sigman performed his Tests 4 Days after the Carpet and Tire Cover had already been Removed from the Car Trunk. Jeff Ashton pointed-out that these Items, especially the Carpet, would have been the Items from which any “Concentraton” would be more-likely found, and, accordingly, on which these Tests should have been done. Sigman did say that he Detected an “Odor”, although he’s not Experienced in “Decomposition”, so he couldn’t Identify. All this “Forensic” stuff continues to be a bit Confusing, but still, Sigman’s Testimony doesn’t override the 7 or 8 who have already stated that they definitely know the “Smell” and Confirmed it. The Defense ultimately did end-up having the better Day, and I think that now makes a total of 2 Days out of 23 so far. What are they DOING???… I think they’re going to Lose the Jury if they keep this Subject-matter up much longer and avoid getting down to Business with all that Evidence they promised to Deliver in their Opening Statement. I just don’t see that The Defense is getting anywhere Significant or Advantageous with this drawn-out Scientific Mumbo-Jumbo, and, with Ashton so Good at it and routinely “Flipping” their own Witnessess, I think it’s time to move on.
