(Updated at 5:10 p.m.) Police are investigating what they’re describing as a “very suspicious death” inside a house on the 1100 block of 18th Street S., in the Aurora Highlands neighborhood, two blocks from the RiverHouse apartment complex.

Police say a 42-year-old single mother was found dead inside the home this morning. So far, they’re not releasing any details about the manner of death.

Police were originally called to the house at 7:50 a.m., when a neighbor saw the woman’s children wandering around outside the house.

The woman had a 3-year-old son and a 5-year-old daughter, who are now in the custody of Child Protective Services, according to Arlington County Police Department spokesman Dustin Sternbeck.

Sternbeck said there had been a history of domestic violence at the residence, and that the woman had taken out a restraining order against a man who also lives in Arlington. Police are in contact with that man but he’s not currently in custody, according to Sternbeck.

Next of kin have been notified, police said.

Property records show that the house is owned by a woman named Bonnie Delgado. On Facebook, an Arlington resident by the same name, who matches a description given by a neighbor, appears to also have a young son and daughter.

Neighbors confirmed to NBC 4’s Pat Collins that Delgado — who was in the midst of a divorce but went by her married name, Dr. Bonnie Black, professionally — is the victim. She was a psychologist who did contract work for the FBI.

So far, police have not officially released the victim’s name. However, police have confirmed that Delgado’s ex-husband, who lived a few blocks away on 21st Street S., is being questioned at Arlington police headquarters. His truck was towed from the scene, NBC 4 reported. He has not yet been named a “person of interest” in the case.

Like other houses in the neighborhood, the trash cans had been pulled to the curb in front of the victim’s home. As a result of the investigation, solid waste collection has been postponed in the neighborhood until Monday, according to the Arlington Dept. of Environmental Services. Police could earlier be seen searching trash cans in the area.

Streets around the murder scene are expected to remain cordoned off by police tape for much of the remainder of the day.

The last reported homicide in Arlington County was in December, in the Westover neighborhood.
