Two FBI crime scene analysts will be allowed to testify at the trial of the man charged with the massacre at a Colorado movie theater.
The judge ruled Wednesday that FBI experts in bullet trajectories are credible and can testify as prosecution witnesses at the trial of James Holmes.
Holmes' lawyers had argued that testimony from crime scene experts is unreliable.
Holmes is charged with multiple counts of murder and attempted murder in the July 2012 attack, which killed 12 people and injured 70. He pleaded not guilty by reason of insanity. Prosecutors are seeking the death penalty.
Holmes' trial is scheduled to start with jury selection on Oct. 14.
