The United States Justice Department's Civil Rights Division is now investigating the shooting death of Milton Hall.
Hall was shot and killed by local police on July 1 when police say he acted aggressively with a knife.
The announcement comes one day after CNN released cell phone video of the incident. NBC25 is not airing the eyewitness video, but Ajhani Owusu said she saw the shooting and remembers it vividly, " Gunshots just rang out. You could see the bullets hitting his body," said Owusu.
The Department of Justice says it cannot provide any further details concerning the investigation at this time.
