BOSTON (AP) -- Federal prosecutors say they'll ask for more time to indict Boston Marathon bombing suspect Dzhokhar Tsarnaev.
Prosecutors said Friday they will not indict Tsranaev within the 30-day period prescribed the Federal Speedy Trial Act. Sunday marks 30 days since Tsarnaev was arrested following the April 15 bombing.
Prosecutors didn't specify under which exception they'd seek an extension.
Earlier Friday a judge denied a request from Tsarnaev's attorneys seeking to take periodic photos of him while he recovers from wounds sustained prior to his arrest.
Tsarnaev's lawyers argued the photos could provide evidence on the voluntariness of his statements and be used in an argument to mitigate his sentence.
The 19-year-old Tsarnaev is charged with using a weapon of mass destruction in the bombings that killed three people and injured more than 260.
