James Holmes Expected to Enter Plea at Court Hearing

Arapahoe County Sheriff's Office(DENVER) -- James Holmes will be in a Colorado courtroom on Tuesday, where he is expected to enter a plea to charges stemming from the deadly shooting massacre at a movie theater in Aurora last summer.

Holmes, 25, is charged with 166 counts, including murder, attempted murder and explosives charges, for allegedly opening fire during a crowded midnight showing of The Dark Knight Rises on July 20.  Twelve people were killed and 58 were wounded by gunfire.  Another 12 people sustained other injuries.

It's widely expected that Holmes will plead not guilty by reason of insanity, however, defense attorneys could still ask the judge to delay the arraignment.  Once a plea is entered, the district attorney will have about 60 days to determine if prosecutors will seek the death penalty.

If Holmes pleads not guilty by reason of insanity, he will be immediately committed and court-appointed psychiatrists will determine if Holmes was insane when he allegedly opened fire at the movie theater.
