DeKalb County police are searching for a man suspected of shooting his girlfriend and leaving her to die in Lithonia, police said.

Christopher Harvey is suspected of killing 31-year-old Derricka Body in a March 24 shooting at the Stonecrest Mill apartment homes, a department spokeswoman said. Officers found Body dead at the scene around 9:45 p.m., but the shooter had already left.

Body’s mother, Regina Scott, told Channel 2 Action News that she learned about her daughter’s death from footage on her doorbell camera. According to Scott, she returned home to find the lights on and her door unlocked. She checked her security camera and saw that police had been at her apartment and left with a body bag, the news station reported.

On the video, Scott could hear her granddaughter describing how Harvey, Body’s boyfriend, allegedly shot and killed the woman, Channel 2 reported. Scott said Harvey left in Body’s car, a black Kia Soul, and took her cellphone.

She was killed in front of her 4-year-old son, her mother said in an online fundraiser for Body’s funeral expenses.

“We are raising money for her burial as well as the aftercare to take on the task to raise three beautiful kids, two girls and one boy,” Scott wrote on a GoFundMe page. “My daughter was a wonderful mother and a loving sister and friend to all that knew her, loved her personality, and she was loved by everyone.”
