The prosecution in the trial of alleged Fort Hood shooter Nidal Hasan will be allowed to admit certain items of visual evidence.

At a pre-trial hearing on Thursday, Judge Colonel Tara Osborn approved evidence that includes multiple photos of the scene of the shooting, diagrams of victims killed in the attack, three 911 calls and a dash cam video. The prosecution argued that the evidence will show that Nidal Hasan planned the November 5, 2009 attack that left 13 dead and over 30 injured.

However, Osborn also ruled that the prosecution may not use any photos of the deceased or a crime scene video during opening statements of the trial. Hasan, who is acting as his own defense counsel, said at Thursday’s hearing that he did not want to see autopsy photos of victims “paraded”, as he is concerned for the dignity of those killed.

The next pre-trial hearing is set for July 31 at 2:30 p.m.
