A California man pleaded not guilty Thursday to wearing military medals that he never earned.

Prosecutors say 39-year-old Steven Burton, who was never in the military, was photographed wearing a Marine Corps uniform displaying the Navy Cross along with the Bronze Star and Purple Heart.

The FBI was contacted after a Navy commander attending her high school reunion saw Burton wearing the uniform and medals.

He was charged with unauthorized wearing of military medals and was released on $10,000 bond. He is due back in court for a Dec. 21 hearing.

If convicted on the misdemeanor charge, Burton could be sentenced to one year in federal prison.
