Carlos Luciano Ledesma was a 34-year-old Chandler Police Department detective and U.S. Marine Corps veteran who was killed on July 28, 2010, in Phoenix, Arizona. He had served with the department for three years and left behind a wife and two children.

Detective Ledesma and two other undercover detectives went to a Phoenix home that day to complete what had been arranged as a sale of a large quantity of marijuana. As the officers arrived they were ambushed; suspects emerged and immediately opened fire. Ledesma was mortally wounded in the shootout. His two fellow officers were wounded but returned fire, killing two assailants at the scene.

Six people were initially taken into custody as the investigation unfolded. Over the following years several conspirators were prosecuted and some reached plea agreements. If anyone knew Detective Ledesma, saw activity at that Phoenix home in July 2010, or has information relevant to the ambush, please come forward.
