A former South Florida pill mill kingpin has been sentenced to 20 years in prison but could serve far less time because of his extensive cooperation with investigators. 

A federal judge imposed the sentence Friday on 43-year-old Vincent Colangelo. He pleaded guilty earlier to drug, tax evasion and money laundering charges. 

Court records show Colangelo's eight clinics in Broward and Miami-Dade counties dispensed at least 660,000 oxycodone and other pills between January 2009 and December 2010. Authorities seized cash, 50 vehicles and other assets from Colangelo after his arrest. 

Prosecutors say Colangelo is helping them build many other cases. They could later recommend a sentence reduction. 

Colangelo was one of 20 people arrested in a February 2011 pill mill sweep, one of several in a recent crackdown.
