NEWPORT, KY (FOX19) - Prosecutors wrapped up their witnesses Tuesday morning with more testimony from forensic experts.
Two analysts with the FBI in Quantico, Virginia, came to testify about forensic evidence at the scene.
Tina Delgado examined blood samples from the scene and determined that DNA on the end of the gun belonged to Bob McCafferty. She did not find any DNA from Cheryl McCafferty indicating that the gun was held to her mouth, but under cross examination, she admitted that the DNA could have been there, but have been wiped off.
Eric Smith, also with the FBI, then took the stand to talk about the gun. He testified that he could not determine if the bullets found in the McCafferty closet were fired from the same gun that was used to kill Bob McCafferty. He did say that several items of clothing contained gun shot residue, indicating that a gun was fired near those articles.
Smith also testified where gun shot residue was found. He found it in two places on the comforter, and on the University of Kentucky t-shirt that Bob McCafferty was wearing when he died. The determination was that the shirt was in close contact with the revolver.
Under cross examination, defense attorney Frank Mungo went back to his main argument that the crime scene was not handled properly. He indicated that the presence of gun shot residue on two areas of the comforter meant it was not folded properly when it was sent to the FBI. Smith also testified that GSR tests from under the comforter were not taken, meaning that its undetermined if Bob McCafferty fired a gun into the closet and then went and laid in bed. The defense argued that Smith's testimony did not eliminate the possibility that Bob McCafferty fired the gun.
