CENTENNIAL, Colo. (AP) — A hearing laying out the evidence against the accused gunman in the Colorado theater shooting ended Wednesday with the defense deciding not to call witnesses to explain James Holmes' mental health.

The judge said he will rule by Friday on whether Holmes should stand trial. If the judge decides he should be tried, Holmes could enter a plea at a hearing scheduled that morning.

Prosecutors argued that they had shown that Holmes acted with deliberation and extreme indifference, presenting evidence that he cased the theater before the July 20 shooting, which left 12 people dead and 70 injured. They also showed photographs they say Holmes took of himself and his arsenal hours before the attack.
