Stephone Reed, who was included by authorities in their list of "the worst of the worst" criminals in Chattanooga, pleaded guilty on Monday in Federal Court to charges of carjacking and brandishing a weapon during a crime of violence.
Reed faces up to 15 years on the carjacking and a minimum of seven years up to life on the gun charge.
He will be sentenced on June 5 by Judge Curtis Collier.
Reed appeared before Federal Magistrate Judge Susan Lee.
Police said Reed, 23, is the "Big Homie" of the local Gangster Disciples.
Prosecutors said on March 31, 2012, Reed and two others carjacked a woman in Brainerd. One of the others brandished a gun. Amanda West told police she was arriving home on McBrien Road when three black males approached her and demanded her vehicle. She said one of the trio, who had dreadlocks in his hair, pointed a gun at her and demanded items she had in her hand as well as the vehicle.
She said when she responded no, another one of the robbers told the gunman, "Shoot her in the leg."
Ms. West said she begged not to be shot and handed over the items. She then ran into her house.
Reed was driving the car later that afternoon in Cleveland, Tn., and led the Tennessee Highway Patrol on a high-speed chase which ended when Reed crashed the stolen car into a building. All three people in the car fled.
Police captured the other two, Anston Baker and Demarquis Dillard, but, due to a miscommunication, let Reed get away (even though they stopped him). Reed was later apprehended.
In the car on the floorboard between the two front seats was a loaded gun. The victim's keys, bag and cell phone were also in the car.
