DENVER—There’s no deal yet for a former CIA contractor accused in a fight over a parking spot in Colorado.

A judge had been set to consider a plea agreement for Raymond Davis on Monday but Davis’ lawyer, William Frankfurt, told him the proposed deal unraveled after the lawyer for the alleged victim, Jeffrey Maes, added unspecified conditions on Friday.

After the hearing, Maes’ lawyer, Larry Klayman, said the deal should include an apology or jail time as well as restitution or anger management classes.

“It just can’t be that you walk away from this without any punishment,” he said.

Frankfurt said the new conditions were making it more difficult to reach a resolution in the case.

The case had been set to go to trial Tuesday but lawyers were not ready to proceed. An angry Judge Richard Brewst Caschette gave them until March 1 to reach a deal or Davis would go on trial July 15.

Davis is charged with felony assault and misdemeanor disorderly conduct in the fight outside a suburban Denver bagel shop. A conviction on the felony charge would carry a minimum 2 years in prison.

The proposed deal had called for Davis to plead guilty to a misdemeanor assault charge in exchange for probation. It also called for him to pay restitution to Maes and take anger management classes.

Davis, then a CIA contractor, was detained by Pakistani authorities in January 2011 after he shot and killed two men he said tried to rob him. Pakistan released Davis that March after the families of the men agreed to accept $2.34 million from the U.S. government.

Klayman has also filed a lawsuit on behalf of Maes and Maes’ wife and two children, who witnessed the fight. The lawsuit claims Maes suffered a fractured vertebrae and other injuries.

Frankfurt disputes the claim that Maes suffered a fracture. He said Maes may have injured himself by allegedly trying to tackle Davis during the altercation.
