CENTENNIAL, COLO. (AP) -- A Colorado prosecutor says the suspect in the mass shooting at a midnight Batman film screening could face the death penalty.

Eighteenth Judicial District Attorney Carol Chambers said Monday that her office is considering pursuing that punishment against James Holmes. She says a decision will be made in consultation with victims' families.

Holmes makes his first court appearance Monday. The 24-year-old former graduate student is being held on suspicion of first-degree murder.

Holmes is suspected in a shooting at a theater in a Denver suburb that killed 12 people and injured 58.
