Forensic experts say DNA doen’t link Dooley to scene in workplace slaying

The results of key DNA evidence was revealed in the David Dooley trial as forensic experts testified about what they found in samples from under the victims fingernails and on her arms.

Forensic biologist John Clemmons Jr., who examined the evidence, testified there was DNA that didnt belong to the victim found in one place on her arms among more than a dozen areas tested.

Foreign DNA was found at one of the 15 locations, Clemmons said. Because it is one location it is too limited for us to do any type of interpretation with.

It couldnt link Dooley to the crime and Dooleys DNA could not be identified in the samples taken from the fingernails either, authorities said.

In all, five different forensic experts were called by prosecutors, including one who analyzed tool marks found on a door that was pried open at the murder scene. None of them could definitively link Dooley to the crime.

Dooley is accused of killing Michelle Mockbee on May 29, 2012, at the Thermo Fischer Scientific plant where he worked as a janitor and she worked in the offices.

The medical examiner said it appeared Mockbee was beaten to death with an industrial tape dispenser. The medical examiner told the jury the injuries she sustained were so severe; its what they usually expect to see in fatal car crashes.

Meanwhile, a detective also called by prosecutors disputed a claim made by Dooleys defense attorneys in their opening statements.

Dooleys attorney, Chris Roach, told the jury, a K-9 unit trained to detect blood evidence indicated there was something in a vehicle that did not belong to Dooley on the morning of the killing.
