DENVER -- Prosecutors are looking into whether they should file more charges against an Air Force officer accused of vandalizing cars with anti-Bush graffiti, his attorney said Tuesday.

Lt. Col. Alexis Fecteau is already charged with eight counts of criminal mischief for allegedly blacking out bumper stickers supporting President George W. Bush on cars and then spray-painting an expletive over them.

Fecteau's attorney, Patrick Mulligan, said a court hearing scheduled for Tuesday was postponed until Dec. 6 while authorities try to determine whether more cars were vandalized.

Fecteau had been director of operations for reserve forces at the National Security Space Institute at Peterson Air Force Base in Colorado Springs, supervising 11 full-time and 30 part-time reservists.

His attorney had said Fecteau was "a highly decorated colonel in the Air Force with 500 combat hours in the Gulf War, Kosovo and Bosnia. Any allegations have to be viewed in that context."

He was reassigned to a non-supervisory position after the charges were filed.

The vandalism occurred while cars were parked at Denver International Aiport between last June and December.

Police named Fecteau after officers left a bait vehicle at the airport equipped with a camera that recorded an image of a suspect and his car.

Investigators matched the car to footage from a camera monitoring cars leaving the parking lot and traced the license plate to Fecteau.
