TAMPA, Fla. (AP) — A once-standout U.S. narcotics agent who used his badge to build a lavish lifestyle of luxury cars and Tiffany jewelry has been sentenced to 12 years in federal prison for conspiring to launder money with a Colombian cartel. But even as Jose Irizarry admitted his crimes Thursday, he blamed colleagues in the Drug Enforcement Administration for fostering a culture of corruption that he says desensitized him to the implications of breaking the law. His attorney says in court papers that Irizarry has met with prosecutors for “endless hours” to detail the criminal activity of others. DEA did not immediately comment.
