Experts: James Holmes' Trial Will Be "Unprecedented" For Colorado in Size, Expense

Accused of shooting at movie theatre in July 2012

A Colorado court will tell potential jurors in the trial of accused theater shooter James Holmes that their service could last up to eight months. Legal experts say the trial will be "unprecedented" for the state in expense, size and pain.

"The Court will instruct prospective Jurors that individual voir dire will last approximately two to three months and that the trial itself may last four to five months," Arapahoe County District Court Judge Carlos Samour wrote in a Wednesday court order. "As such, they should plan to be available to serve on this case for six to eight months."

The judge noted that the time is an estimate that it is "better to err on the side of overestimating the duration of the trial."
