Federal prosecutors asked a judge Monday to bar Boston Marathon bombing suspect Dzhokhar Tsarnaev from seeing some of the gruesome autopsy photos of the three people killed in the attack.
    
In a court filing, prosecutors said Tsarnaev should only be allowed to look at autopsy photos that will be used during his trial and sentencing. They said he should not be allowed to see the many other photos that will not be used against him in court.    

"Allowing photos of the mutilated bodies of the victims to be viewed by the man accused of mutilating them would needlessly revictimize the family members in the same way that innocent children who are photographed pornographically are revictimized whenever those photos are seen by others," prosecutors wrote.
    
Miriam Conrad, one of Tsarnaev's lawyers, declined to comment on the request.
    
In their motion, prosecutors say they told the defense that if Tsarnaev were allowed to view all the photographs, the government would continue to make them available for lawyers' review but would not provide copies. They said Tsarnaev's lawyers "refused to accept any limitation on Tsarnaev's ability to view the autopsy photos and repeated their demand for copies of all of them."
