Charlotte-Mecklenburg police have arrested a suspect in the Dec. 28 Concord Mills shooting that killed 13-year-old Avenanna Propst and injured two other teenagers.

CMPD officers say they arrested 18-year-old Dontae Laquavious Milton-Black of Charlotte Wednesday morning. Concord police then charged him with one felony count of first degree murder and one felony riot count.
The Concord Police Department says Milton-Black was not targeting Propst or the two teenagers who suffered gunshot wounds. Instead, the shooting stemmed from a fight that broke out between Milton-Black and an unidentified 16-year-old male inside the mall just before closing time.
Police say that as the fight went on, the 16-year-old observed that Milton-Black had a gun. Both him and Milton-Black were asked to leave the mall, along with the group they were with, using the mall entrance near Sun & Ski and AMC Theatres. The 16-year-old, fearful that Milton-Black had a gun, exited through the nearby Dave & Buster's. Police say Milton-Black saw him exit to the parking lot and fired at him, hitting 13-year-old Propst and the two male teenagers she was with.
Propst, who was an eighth-grader at ACE Academy Charter School in Harrisburg, died at the scene.
Concord police also determined that the Concord Mills shooting was not related to the fatal shooting of 31-year-old Derron Jordan earlier Saturday. Jordan was a cousin of Propst. He was shot near Lincoln St. and Polk Ave. in Concord a couple hours before Propst was killed.
Milton-Black has been transferred to Cabarrus County jail with no bond and is awaiting additional charges.
Correction: An earlier version of this story said Derron Jordan was killed Dec. 29. He was fatally shot Dec. 28.
