Austin Wolf -- a popular gay porn star -- is headed to prison for nearly two decades after being convicted of horrific crimes involving children. Federal prosecutors in New York announced Monday that the 44-year-old was sentenced to 19 years behind bars for enticing a minor to engage in illegal sexual activity and for a pattern of prohibited sexual conduct. The decision was handed down after the adult film star pleaded guilty. Smith's arrest followed a sting operation in which he arranged to meet what he believed was the father of a 7-year-old child for sex. Law enforcement intervened before the encounter could take place, seizing the massive trove of child abuse material in his home.
