Prosecutors in the Colorado theater shootings are asking the judge not to allow testimony about state execution procedures if James Holmes is convicted of murder.
The district attorney's office filed a series of pre-emptive motions released Monday that seek to limit what witnesses can say during the sentencing phase if Holmes is convicted.
Holmes pleaded not guilty by reason of insanity to charges of killing 12 and injuring 70 in July 2012.
Prosecutors are seeking the death penalty. Under Colorado law, that means if the jury convicts Holmes of murder, the same jury decides whether he should be executed or sentenced to life without parole.
Also Monday, a judge ordered a Fox News reporter to return in September for possible questioning about her confidential sources for a story about Holmes.
