The Navy set an Oct. 26 trial date Tuesday for an officer charged with spying and a litany of other crimes.

Lt. Cmdr. Edward C. Lin faces two counts of espionage, three counts of attempted espionage and five counts of communicating defense information, among other things. He has pleaded not guilty.

Charging documents show military prosecutors believe Lin committed espionage from 2012 to 2014 in the Washington area.

Lin served for most of that time as a staff aide to Vice Adm. Joseph Mulloy. Mulloy was serving as the deputy assistant secretary of the Navy for budget and the director of the fiscal management division, according to a Navy biography.
