“Other testimony was given Thursday by Brian Wraxall, a forensic serologist, who tested blood recovered from Radke’s car.

By testing two genetic markers, Wraxall said, it was determined that the blood found under two of the wheel wells could have belonged to Rudiger but did not belong to Radke.

Combining his data with testimony delivered by another expert yesterday, Wraxall said the blood sample matched Rudiger’s and only .044%–or one person out of 2,272–of the Caucasian population as the same kind of blood.”
