A Maryland man has been arrested in Virginia and charged with a double murder in southeastern Washington, D.C., earlier this week.

Keanan Christopher Turner faces two counts of first degree murder while armed in the death of Wanda Wright, 48, and her daughter Ebony Wright, 32, on Monday evening. He’s also been charged with two counts of assault with intent to kill while armed for shooting another woman and setting fire to the apartment while that woman and 3-month-old baby were inside.

Police said that Ebony Wright was the baby’s mother, and Turner was the father.

Court documents say firefighters arrived on scene and were quickly approached by a young woman, who had been shot, carrying the baby, WUSA reported. They found Wanda Wright outside the apartment and Ebony Wright inside the apartment, both shot in the head. The older woman was pronounced dead at the scene, and her daughter was rushed to a hospital, where she was pronounced dead.

The other woman, identified as the baby’s aunt by Fox 5 DC, was taken to a hospital and treated for non-life-threatening injuries. The baby was not injured.

Police said a Ring doorbell camera captured Turner at the door, and they found child support papers inside that Ebony Wright had served on Turner, according to WUSA.

The aunt, who has not been named, told police that Ebony Wright had asked Turner to come and see the baby for the first time. She said she was in a bedroom getting clothes for the infant and heard two gunshots.

She hid in a closet, she said, and Turner found her. As she screamed for mercy, he shot her in the face, then left the apartment. She stumbled out of the closet, grabbed the crying infant, and fled the apartment.

Investigators arrested Turner, who lives in Prince Georges County, Maryland, at his father’s home in Stafford, Virginia. They said they found hundreds of firearms in the home, many stuffed under mattresses and into chair cushions.

fter his arrest, police said, Turner told detectives he worked for the government. “Things went left,” he said about the shooting, “and that’s why I did it.”
