SANTA FE, N.M. (AP) — The lawyers for a former New Mexico deputy accused of killing his partner in 2014 are asking the court to dismiss their client's case. The defense attorneys for former Santa Fe deputy Tai Chan filed motions Wednesday that claim their client is a victim of outrageous government conduct in what they call a botched investigation by Las Cruces Police Department. The attorneys are also asking District Attorney Mark D'Antonio be dismissed from the case. The motions argue that D'Antonio has a conflict of interest in the case because of a related lawsuit filed by another detective. The District Attorney's Office has declined to comment. Chan accused of killing Deputy Jeremy Martin. Officials say the two had an alcohol-fueled argument on October 2014 before Chan fatally shot Martin.
