A judge sentenced an Arlington man to two consecutive life sentences for the 2015 murder of his estranged wife, police said Thursday.

The man, David Black, 45, was sentenced Wednesday in Arlington County Circuit Court. Authorities said that in April 2015, just before the couple’s divorce was finalized, Black fatally stabbed his wife, 42-year-old Bonnie Black, while their two young children — then 5 and 3 — slept nearby.

Bonnie Black was a psychologist who did contract work for the FBI. Investigators went to the family’s 18th Street South home after their children were spotted wandering outside, and officers found Black’s body.

Authorities said detectives began an intensive investigation that revealed that Bonnie Black was the victim of domestic violence. David Black was arrested in October 2015; in November, a jury found him guilty of first-degree murder and burglary while armed with intent to commit a felony.

“Unfortunately nothing can bring Bonnie Black back to her loving family, colleagues and friends,” said Arlington County Deputy Chief Daniel J. Murray in a statement, “but it is our fervent hope that we have been able to provide them with some closure.”
