Colorado theater shooting suspect James Holmes is returning to court Friday for a hearing on whether crime scene reconstruction experts should be allowed to testify at his trial.

Friday's hearing will be open to the public and media. A hearing earlier this week was closed because the topic was whether Holmes should undergo another psychiatric evaluation, and the judge ruled the testimony would taint the jury pool.

The judge hasn't said if he'll allow another evaluation.

Holmes has pleaded not guilty by reason of insanity to charges of killing 12 people and injuring 70 at a Denver-area movie theater in July 2012. Prosecutors are seeking the death penalty.

Holmes' lawyers want the judge to bar evidence about crime scene reconstruction, saying it's unreliable.

Prosecutors' response to the defense request hasn't been made public.
