The judge in the Colorado theater shootings says as many as 3,500 prospective jurors will be summoned when the case goes to trial.
Judge Carlos A. Samour Jr. included the estimate in a ruling dated Friday. The ruling granted a defense request to have all prospective jurors fill out questionnaires before they are questioned by lawyers.
James Holmes is scheduled to go on trial in February on more than 160 counts of murder and attempted murder. He's accused of planning and executing an assault on a packed movie theater in a Denver suburb in July, killing 12 and injuring 70.
He has pleaded not guilty by reason of insanity and will undergo a mental evaluation at the state hospital before the trial.
Prosecutors are seeking the death penalty.
