Direct examination of Dr. Arpad Vass by JA continued.
He agreed he also examined scrapings of the wheel well of the car. He identified the package as being the sample.
ICA sitting expressionless.
Scrapings admitted into evidence over defense objection as Exhibit 125.
He did a chemical extract of the scraping - of particular interest - acidic acid found which is a byproduct of human decomp and also of manufacturing of chloroform.
He also received paper towels from Dr. Neil Haskell. He identified the package.
