A 49-year-old Kentucky man who worked as a technical writer for Insitu in 2011 was sentenced by a federal judge in Yakima to three months in prison for selling trade secrets involving drone aircraft. Stephen Martin Ward was found guilty in April of stealing trade secrets under the federal Economic Espionage Act. U.S. Attorney for the Eastern District of Washington Michael Ormsby says Ward was arrested in November 2011 in Indiana after giving a digital copy of an unmanned aircraft maintenance manual to an undercover agent for 10-thousand dollars. Ormsby says Ward was hired by Insitu as a technical writer in August 2011 to create a maintenance manual for a drone. On Thursday, federal District Judge Rosanna Malouf Peterson sentenced Ward to three months in prison and ordered him to have no contact with Insitu, parent company Boenig, or its employees.
