Michelle Hannon, a DNA analyst with the State Bureau of Investigation Crime Lab, testified that she tested a root from a piece of hair taken from the couple's bedroom that didn't match DNA profiles of either Michelle Young or Jason Young.
She also tested two cigarette butts – one that defense attorneys say was found in the garage and another found in the doorway leading into the kitchen of the Young home – that contained two different sets of DNA from unknown males.
A partial DNA profile from a jewelry box in the couple's bedroom also excluded Jason Young as a contributor to that sample.
The only definitive DNA matches to Jason Young that were found were from a piece of sheet rock taken from the couple's bedroom wall and semen found on the bed sheet.
Special agents with the SBI also testified that two shoe impressions found on pillows were determined to be a pair of size-10 Franklin athletic shoes and a pair of discontinued Hush Puppies-brand shoes.
Further DNA testing on what has been described as a red lava rock found at a Hampton Inn in Hillsville, Va., contained a partial DNA profile that couldn't exclude Jason Young, said Shawn Weiss, a DNA analyst with LabCorp.
Tests found that the same sample could potentially belong to 1 in every 79 Caucasian males, Weiss said. That indicated to him that it was nowhere near to being a match to Jason Young's DNA.
