Lawton Inmate Indicted For Threatening The D.A.'s Office

A federal grand jury indicted a Texoma inmate for threatening the Comanche County District Attorney's office.

Lloyd Alan Cooper, 41, is accused of mailing a letter filled with white powder, on November 16, 2010 and a note that said "God save us".

Officials also said Cooper mailed the letter from the Geo Lawton Correctional Facility with the intent to convey a threat.

If convicted, Cooper faces up to five years in federal prison, a fine of up to $250,000, and a period of supervised release of up to three years.

These charges are the result of an investigation conducted by the Federal Bureau of Investigation, the Comanche County Sheriff's Office, and the Lawton Police Department. The case is being prosecuted by Assistant U.S. Attorney Andre' Caldwell.
