Virginia man convicted of killing his wife

Arlington, VA

After a day of deliberation, an Arlington jury convicted David Black of first-degree murder in the killing of his estranged wife Bonnie. The victim was stabbed in her bedroom while their two young children slept nearby.

Cybergenetics Dr. Mark Perlin testified at the trial about DNA mixture evidence. TrueAllele® computer analysis showed that the defendant left his DNA on the master bedroom switch, but not on the bathroom switch. Prosecutors concluded that David Black had recently been in the home, contradicting his story. TrueAllele distinguished parent and child DNA, refuting defense claims that the mixture came from his children.

Jurors recommended two life sentences.
