Jacobe Payton has not yet been formally charged, but police say he's responsible for the murder of De'maree Adkins. She was shot after a wreck on the South Belt near Fuqua Saturday morning.
Investigators say the car her mother was driving collided with another vehicle that had been speeding along the feeder. After the wreck, someone drove up and opened fire into the car.

Adkins was shot and killed. Detectives say she was not the intended target.
Investigators have asked the media not to show Payton's mugshot out of fear that doing so could jeopardize their investigation as they're still looking to make other arrests.

Police will not say how they caught Payton or what information led to him. His attorney, Tiffany Hill, said she has not spoken to him yet.
"I couldn't see him being involved," Hill told Eyewitness News.
Latoyia Jarmon-Thomas, De'maree's mother, said the arrest will never bring back her little girl.
Payton has two current assault charges pending in Fort Bend County and a charge of theft out of Harris County. He declined ABC13's request for interview at the jail where he is held in lieu of $500,000 bond.
