WEST PALM BEACH (CBS4/AP) — The co-owner of four South Florida pain clinics responsible for illegally distributing some 20 million pain pills was slapped with a prison sentence of more than 15 years.

On Friday, Jeffrey George, 31, learned the faith of his actions from Judge Kenneth A. Marrain in West Palm Beach. George and his twin brother Christopher George operated, managed and financed four clinics in Broward and Palm Beach counties. According to authorities, the brothers made $40 million from the illicit sale of oxycodone and other drugs from 2008 to early 2010.
