James Holmes, the man accused of gunning down a dozen people at an Aurora, Colorado movie theater will be back in court later this morning for day one of a preliminary hearing.
For the first time since the shooting last July, attorneys are expected to publicly provide extensive details about the case.
During the week long proceedings, the judge is expected to hear 911 calls, see snippets from hours of video, and listen to witnesses, including police officers and victims.
A ruling last week allows defense testimony about Holmes' mental state, despite the prosecution's objections.
"One of the problems for the defense in the Holmes case is by going through the prelim hearing much of the highly inflammatory and prejudicial evidence they have been able to keep from the public will be made public in open court," says legal analyst Scott Robinson.
