MGN MIAMI (AP) – A convicted kingpin of South Florida pill mills that illegally sold millions of dollars’ worth of powerful prescription painkillers is seeking a cut in his prison sentence. The attorney for Vincent Colangelo has asked a Miami judge to reduce his sentence from 20 years to 16 years. Attorney Alvin Entin says a retroactive change in federal sentencing guidelines justifies the reduction. Colangelo was sentenced in 2012 after pleading guilty to federal drug, money-laundering and tax charges. Court documents show he operated six pain clinics that made an estimated $22 million in profits through illegal sale of oxycodone and other drugs. Six other people were charged in the case. South Florida was once the nation’s pill mill leader, but new laws and tougher law enforcement has all but eliminated them.
