The father of Michael Brown, the unarmed black teen who was fatally shot by officer Darren Wilson in Ferguson, Missouri, is still pushing for justice in his son’s death.

Michael Brown Sr. sat down with CBS News for the fifth anniversary of the teen’s death, which occurred on Friday. Wilson, who’s white, did not face charges following his deadly use of force.

Brown Sr. told the outlet that he “would like for Wesley Bell to reopen the case,” referring to the first-term St. Louis County prosecutor. The father noted that he’s been in contact with the official.

In January, Bell replaced seven-term incumbent Bob McCulloch, who was heavily criticized for failing to bring charges in Brown’s case.

While Bell has not publicly commented on the possibility of reopening the case, he released a statement this week on the killing of Michael Brown.

“Our office is doing everything we can to understand the underlying issues that contributed to the tragic death of Michael Brown,” Bell said. “We are working every day with the community and law enforcement to implement policies and reforms that meaningfully address those issues, and help this community and this region heal.”

Then-Attorney General Eric Holder launched an investigation into Wilson’s actions back in 2014. The Justice Department later concluded that Wilson would not face federal civil rights charges, as it found that the officer’s use of deadly force against the unarmed teen could not be proven to be considered “objectively unreasonable.” Federal charges in the case were not appropriate, the DOJ found.

“There is no evidence upon which prosecutors can rely to disprove Wilson’s stated subjective belief that he feared for his safety,” the DOJ’s report read.
