David Black gets two consecutive life sentences
In 2015, David Black fatally stabbed psychologist Bonnie Black, his estranged wife, in her Arlington home as their young children slept nearby. Cybergenetics Dr. Mark Perlin testified at the November trial about DNA evidence. TrueAllele computing connected the killer to mixed DNA left on a bedroom light switch. The jury convicted Black of first-degree murder.
On February 9, the judge sentenced Black to two consecutive life sentences. "Unfortunately nothing can bring Bonnie Black back to her loving family, colleagues and friends," said Arlington County Deputy Chief Daniel J. Murray, "but it is our fervent hope that we have been able to provide them with some closure."
