Former University of Memphis basketball players Shawne Williams, 24, and Kareem Cooper, 25, were detained on separate charges today when detectives spotted Williams driving his Dodge Charger down Winchester Road without a seatbelt.

Officers reported they detected a strong odor of marijuana wafting from Cooper, who was in the passenger seat near Graceland at the time of the routine traffic stop. As Cooper stepped out of the vehicle, he turned over a handgun loaded with 20 rounds to detectives, who quickly spotted a bag of marijuana weighing 17.2 grams concealed in his crotch area, police said.

Cooper was charged with possession of marijuana with the intent to manufacture/deliver/sell and felony possession of a firearm. No bond has been set.

Williams, a former Conference-USA tournament MVP and the driver of the vehicle, presented officers his driver's license, suspended Feb. 12 for failure to satisfy a citation. A physical arrest was made to prevent the offense from continuing, the police affidavit said. His bond is set at $250.

Williams is still awaiting trial Oct. 1 for the January indictment for four counts of possession of a controlled substance with intent to manufacture/deliver/sell and four counts of conspiracy to manufacture/deliver/sell a controlled substance, a codeine-based syrup. His bond was set at $16,000.

Cooper was last booked on July 10 for domestic assault with bodily harm, records show. His bond was set at $2,500.
