Police: Colo. shooting suspect planned massacre

CENTENNIAL, Colo. (AP) — The prosecution's final witness is expected to continue his testimony today at a hearing to determine if the Colorado theater shooting suspect should stand trial.

Detectives testified yesterday that James Holmes spent more than two months planning his attack on a midnight screening of "The Dark Knight Returns." They also said he rigged an elaborate booby-trap system in his apartment to distract police from the carnage at the theater, though the traps were never sprung.

One detective testified that Holmes, after his arrest, played with the paper bags they placed on his hands to preserve gunpowder evidence, pretending they were puppets.

Lawyers for Holmes are expected to present an insanity defense as they have previously stated that their client is mentally ill.

Holmes is charged with killing 12 people and injuring 70 in the July 20 massacre.
