Detectives Daniel Joyce and Robert Lopez, who work for separate local law-enforcement agencies under the North Metro Task Force, are suing their respective chiefs [2] as well as task-force supervisors. The two claim they faced retaliation after blowing the whistle on a possibly crooked cop, who may have tipped off suspects before the massive drug bust involving local restaurateur Dan Tang (via 7News [3]). Tang, known for hosting political heavyweights like former President George W. Bush, pleaded guilty in November to drug conspiracy charges involving a money-laundering operation. Adams County Sheriff Doug Darr, a member of the Board of Governors that oversees the task force, dismisses the allegations in the suit, telling Westword [4], "I've never seen such a collection of false accusations and lies in my life." For instance, he says, Joyce and Lopez claim task-force superiors told them and colleagues not to cooperate with an internal investigation launched by the DEA to uncover the possible cop-snitch. Some supervisors stopped working with the DEA altogether, the suit claims. Never happened, Darr says. Last summer, Westword [5] launched an investigation into the alleged corruption. Or read their Cliffs Notes version in this timeline [6]. Tang is scheduled to be sentenced on Wednesday. Vanessa Martinez contributed to this post.
