Hennepin County Attorney Mike Freeman said Tuesday that he has asked the state Bureau of Criminal Apprehension (BCA) to expand its investigation into the shooting death of Jamar Clark.
In an interview, Freeman said, "What we discovered in the case is that a number of things were not completed and they were sent back [to the BCA] to get done. New things have to be investigated."
Freeman said he still hopes to have a decision on charges by the end of March.
Chuck Laszewski, Freeman's communications director, said Tuesday afternoon, "We are not prepared to speculate if there will be a delay and if so how long it will be, but we've worked real hard to be transparent about the Jamar Clark case and if we see we can't make the March 31st date we will let the public know."
Freeman declined to elaborate on what precisely his office had requested of the BCA, but said, "If certain tests do not give results, we are going to have to try something."
He also added: "It is not unusual at all to send things back and have additional investigation done."
Clark, a black man, was shot in a scuffle with two white police officers in north Minneapolis on Nov. 15. He died Nov. 16. His death touched off a series of demonstrations demanding the officers be charged.
Some witnesses say Clark was handcuffed at the time he was shot, while the Minneapolis Police Federation says Clark was not handcuffed and was reaching for an officer's gun.
