Court documents shed new light into killing of Arlington mother

WASHINGTON – Search warrants related to the fatal stabbing of an Arlington County mother and psychologist reveal that her husband’s behavior was increasingly harassing and menacing as the couple approached a final court hearing for their divorce.

Bonnie Black was found stabbed to death in her bedroom in April after her two young children were found wandering outside the Aurora Highlands house. She was stabbed in the chest a week before that final court date.

Last month, her estranged husband, David Black, was indicted for murder in her death.

Police say David Black has no alibi for his whereabouts at the time of his wife’s murder. Investigators have not yet found the murder weapon.

Ninety-five pages of documents were released Thursday detailing new information about the case. Investigators lay out their case in requests for electronic and digital information related to David Black.

In the court documents, police say that David Black has a long history of violence and arrests including as a juvenile. Last Thanksgiving, he assaulted his wife, leading to a protective order barring Black from his wife’s home.

Bonnie Black had confided in a friend that her husband had been taking money from her and forging checks. The friend also told the FBI that David Black had threatened to ruin his wife’s security clearance.

Bonnie Black had been a psychologist and performed contractual work for the FBI.

In 2014, David Black had called the FBI when Bonnie Black had taken their children to Pennsylvania in fear after her husband had threatened that she would never see them again. And days before her death, Bonnie Black had received repeated phone calls from her husband, who made more threats.

She told her friend that she felt like she was living in a “Scream” movie.

Police also learned that David Black recorded every encounter with his estranged wife and primarily communicated with her through text messages and emails.

Investigators requested access and records related to Black’s iCloud account, cellphone and various email accounts along with his accounts for Amazon and PayPal.
