Colorado prosecutors are expected to file formal charges against James Holmes, the former neuroscience student accused of killing 12 people and wounding 58 others at an Aurora movie theater.

Attorneys will also argue at this morning's hearing over a defense motion to find out who leaked information to the news media.

The information included details about a package the 24-year-old former neuroscience graduate student allegedly sent to his psychiatrist at the University of Colorado Denver.

Legal analysts expect the case will be dominated by arguments over the defendant's sanity.

Holmes allegedly began stockpiling gear for his assault four months ago, well before the shooting spree just after midnight during a showing of the Batman film "The Dark Knight Rises." He was arrested by police outside the theater.

SUING THE THEATER

The mother of victim Rebecca Wingo has retained a lawyer and plans to sue Cinemark, the owner of the Century 16 theater where the shooting took place according to TMZ.

Shirley Wygal is filing on the belief that the theater's emergency exit should have been alarmed or a security guard nearby. Holmes is said to have purchased a ticket to the fateful screening and then left the theater, propping open the door unnoticed before arming himself and re-entering the theater.
