Master Sgt. Reinaldo Pagan, who has been with the Hayward Police Department for nine years, is one of two reservists who have had charges brought against them as part of an "extensive and ongoing investigation into the mishandling and compromise of classified information," said Maj. Jason Johnston, a spokesman for the Marine Corps.
Pagan has been charged with dereliction of duty and orders violations.
Gunnery Sgt. Eric Froboese has also been charged with dereliction of duty and orders violations, as well as conspiracy and wrongful transmission of classified information.
Both men are assigned to the Headquarters and Support Battalion of the Marine Corps out of Camp Pendleton.
"These charges, along with supporting evidence, will be forwarded through the appropriate chain of command for review and recommendations as to disposition," Johnston said in a prepared statement.
He said the details of the case are being withheld in order to protect the integrity of the investigation.
"When appropriate and in full compliance with applicable laws and regulations, the Marine Corps will release further information related to the investigation," Johnston said.
