Two suspects in a shooting that left a 7-year-old Atlanta girl dead and her mother injured are now in custody nearly a week after the violence, police say.

The shooting happened around 9:45 p.m. on Feb. 24 at a home on the 2200 block of Tiger Flowers Drive NW.

Investigators believe the shooting stemmed from a dispute between one of the victim’s family members and the gunman over the phone. Thirty minutes after the argument, the suspect came back and fired shots into the home, police said.

Officers responding to the scene found a 44-year-old woman and her daughter, identified as 7-year-old Zoe Price, shot. Medics rushed the pair to a local hospital, but Price died from her injuries.

Atlanta Police Chief Darin Schierbaum said the department’s homicide unit secured an arrest warrant for 19-year-old Preston Smith two days after the shooting. Smith turned himself in to the Fulton County Jail on March 2.

Schierbaum said officers executed a search warrant on Feb. 27 at a home on McDaniel Street. On that day, 17-year-old Steven Richardson, who police described as an “accomplice,” turned himself in to authorities.

Both men are charged with murder, criminal attempt to commit murder, three counts of aggravated assault, second-degree criminal damage to property, possession of a firearm during the commission of a felony, and four counts of third-degree cruelty to children. Richardson is also charged with possession of a Firearm by a Person Under 18.

At a press conference to announce the arrests, Atlanta Mayor Andre Dickens described Price as a bright and compassionate little girl who was “full of energy and full of joy.”

“Her life was cut short in an act of senseless violence, and that loss is not abstract. It is a chair that is going to be missing at the dinner table each night. It is an empty classroom seat next to her friends,” Dickens said.

The mayor called the arrests “a step forward towards justice” for Price’s family and families across the city.

Dickens said that violence, like the act that took Price’s life, would not be tolerated in Atlanta.
