James Holmes is returning to court Monday for two weeks of hearings focusing on what evidence prosecutors can use against him in the Colorado theater shooting case.

Holmes is charged with killing 12 people and injuring 70 others in 2012. He pleaded not guilty by reason of insanity. Prosecutors are seeking the death penalty.

Some of the evidence in dispute comes from two dating websites where Holmes set up accounts before the shootings. Prosecutors say that in his website profiles, Holmes asked, "Will you visit me in prison?"

Prosecutors say they plan to use that to show Holmes knew the shootings were wrong, undercutting his insanity plea.

The judge has already rejected one defense attempt to suppress the website evidence.

Trial is scheduled for next year.
