Holmes lawyers, prosecutors tussle over evidence, seeking advantage in debate over his sanity

Attorneys in the Colorado theater shootings are battling over what evidence can be admitted during James Holmes' trial — aiming to build up or tear down the case that he was insane.

On Wednesday, they sparred over evidence that was seized from Holmes' car and computers.

Thursday, they're scheduled to argue over statements Holmes made to officers after he was arrested and taken to a police station.

Holmes pleaded not guilty by reason of insanity to multiple counts of murder and attempted murder.

His attorneys acknowledge that he was the shooter in the July 2012 massacre, which killed 12 and injured 70. But they say he was in the midst of a psychotic episode.

Trial is set to start in February.
