(CNN) - The trial of accused Colorado theater shooter James Holmes has been delayed again.
His trial was scheduled to begin in October.
But a psychiatrist conducting a second sanity examination on Holmes asked for more time to complete the examination. That's according to a judge's order from Arapahoe County District Court.
A new trial date is set to be scheduled at a hearing on July 22.
Holmes is accused of shooting dozens of people in a packed movie theater during a midnight showing of the Batman film The Dark Knight Rises in July 2012. Twelve people died in the attack.
Holmes has pleaded not guilty by reason of insanity to the 166 charges he faces in connection with the rampage.
