A former Aventura veterinarian who admitted to child porn and bestiality charges will remain behind bars for decades. A Miami federal judge sentenced Prentiss Madden to nearly 22-years in prison. Earlier this year the 40-year-old pleaded guilty to all five counts he faced. Federal investigators say Madden not only had thousands of pornographic images of young children, but he also made and shared videos of himself having sex with dogs. Today Madden confessed to being a victim of sex abuse as a child. This was the first time someone in South Florida had been charged with federal animal cruelty charges.
