Jury selection got underway Tuesday in Aurora, Colorado, where 27 year old James Holmes is accused of a shooting rampage in a movie theater in 2012.
The attack left 12 dead and 70 wounded.
Holmes has admitted to the shooting but pled not guilty by reason of insanity.
An initial 9,000 people were selected as potential jurors. The judge announced today, the number has been whittled down to 7,000 - and over the course of the next three to four months, 12 jurors and 12 alternates will be selected.
The complete trial may take up the whole of 2015.
