Hennepin County Attorney Mike Freeman says he wants the Bureau of Criminal Apprehension to provide him with more details in its investigation into the death of Jamar Clark.
Freeman told the Minneapolis Star Tribune that a "number of things were not completed and they were sent back [to the BCA] to get done." Freeman would not say what was missing.
Minnesota Department of Public Safety spokesperson Bruce Gordon says coming back to the state for more information is "not unusual. It's part of the prosecutorial review process. That's why this remains an open and active investigation."

Clark, a 24-year-old African-American man, was fatally shot November 15 in a confrontation with Minneapolis police.
His death prompted nearly three weeks of protests outside a north Minneapolis police station. Protesters say he was handcuffed when he was shot. A police union leader says Clark attempted to grab an officer's gun.
Freeman said he still hopes to have a decision by the end of March on whether to criminally charge the officers involved.
