Federal prosecutors in Pittsburgh have charged a former executive for a defense contractor with ties to Rep. John Murtha (D-Pa.) with taking nearly $200,000 in kickbacks from a subcontractor.

Richard Ianieri, former president and CEO of Coherent Systems International Corp., is accused of accepting the kickbacks from a subcontractor identified only as “K” in court documents filed Monday. The charges came in the form of a criminal information, an indication that Ianieri is working with prosecutors and plans to plead guilty.

The charges are the first in an ongoing criminal investigation into defense contractors who have received congressional earmarks.
