A man and a woman were shot overnight in a car in the parking lot of a restaurant at Fredericksburg Road and Medical Dr. on the city's northwest side, News Radio 1200 WOAI reports.
Police say the couple had agreed to meet the man, apparently to sell the necklace. When things went bad, police say the man chased them down and started shooting, hitting both of them in the legs.
The victims are being treated at University Hospital for non life threatening wounds.
The gunman remains at large.
