CENTENNIAL, Colo. - Court documents say prosecutors in the Colorado theater shootings have listed about 3,500 potential witnesses they could call during the trial of defendant James Holmes.
The estimate was in a defense motion filed Tuesday, in which Holmes' lawyers requested more time to work through the list and perform a "complete and thorough conflict of interest check with respect to all named witnesses."
The number illustrates the complexity of the case. Lawyers also say nearly 40,000 pages of documents about evidence have been filed.
There is so much evidence, in fact, that a detective with the Aurora Police Department is assigned to work full-time managing the information.
The shooting, which occurred during a showing of the "The Dark Knight Rises," left 12 moviegoers dead and injured 70 people.
Holmes, a 25-year-old former University of Colorado graduate student in neuroscience, is charged with 166 counts in the July 20 shooting. The charges include multiple counts of murder and first-degree murder and prosecutors are seeking the death penalty.
Holmes' lawyers have indicated a desire to change his plea to not guilty by reason of insanity, but the judge hasn't decided on that yet.
Another judge entered a standard not guilty plea on Holmes' behalf in March when his lawyers said he wasn't ready to plead.
Judge Carlos Samour has scheduled the Holmes trial to begin on February 3, 2014. Prosecutors suggested the trial might take three months, while the defense team said it would likely take nine months. The judge scheduled the trial for four months.
