CONCORD — Dontae Milton-Black, the teenager charged in the shooting death of a 13-year-old girl in the parking lot at Concord Mills Mall, was given an additional charge.

On Friday, police charged Milton-Black with assault with a deadly weapon with intent to kill or inflicting serious injury, according to Concord police.

That charge comes with an additional $500,000 bond.

A 15-year-old was also charged with murder. Police said they are working with juvenile authorities to charge him with the additional charge.

Milton-Black made his first appearance in Superior Court on Monday. His next court date is scheduled for March 2.

The 18-year-old from Charlotte is already at the Cabarrus County Jail on murder charges in the shooting death of 13-year-old Aveanna Propst on Dec. 28.

Those charges carry no bond.

Milton-Black was taken into custody Jan. 1 by the Charlotte-Mecklenburg Police Violent Criminal Apprehension Team.

Police identified him as the man who shot and killed Propst and wounded two juvenile boys outside Dave & Buster’s.

Police said the three who were shot were not involved in a previous altercation that started inside the mall near GameStop.

Concord police and Cabarrus County sheriff’s deputies responded to reports of a fight near the outside entrance to Dave & Buster’s at Concord Mills Mall.

As the officers were responding, reports of gunfire were received by 911 dispatchers.

Law enforcement officers found three teenagers with gunshot wounds.

Police said the investigation disclosed that as the mall was approaching closing time, Milton-Black became involved in a verbal altercation with a 16-year-old boy inside a common area of the mall near GameStop.

As the altercation escalated, the 16-year-old observed Milton-Black holding a firearm in his clothing, according to police.

Police said Milton-Black and other teens were directed to exit the mall via Entrance 1 near Sun & Ski Sports and AMC Theatres.

The 16-year-old, fearful that Milton-Black was in possession of a firearm, exited through Dave & Buster’s to the parking lot, according to police.

Police said that upon exiting via Entrance 1, Milton-Black saw the 16-year-old outside Dave & Buster’s, at which time he began to fire in his direction, striking two male juveniles and killing Propst.

Police said the two male juveniles ran back into Dave & Buster’s for protection after being shot and to seek medical attention.
