Michael Brown's father wants investigation reopened The father of Michael Brown is seeking a new investigation of the white Ferguson police officer who fatally shot the black and unarmed teenager nearly five years ago

FERGUSON, Mo. -- The father of Michael Brown is seeking a new investigation of the white Ferguson police officer who fatally shot the black and unarmed teenager nearly five years ago.

Michael Brown Sr. says that on Friday, the anniversary of his son's death, he will speak at a news conference in Clayton and urge St. Louis County Prosecutor Wesley Bell to reopen the case.

Officer Darren Wilson killed Brown on Aug. 9, 2014, during a street confrontation. Wilson claimed self-defense, saying Brown was coming at him menacingly moments after attacking the officer inside Wilson's police SUV.

The shooting set off months of often-violent protests. Demonstrations escalated again in November 2014 when a grand jury's decision not to indict Wilson was announced. Wilson resigned that same month.
