"I stand by what I did, I stand by my training and I have to wait and see what they determine," Wilson said Thursday confirming he was confident no charges would be brought against him.
There is another investigation going on right now aimed at determining whether Ferguson police had a patter of discriminatory practice, according to ABC News.
On November 26, Wilson's lawyer Neil Bruntrager said Wilson was set to leave the Ferguson Police Department and there was a possibility that he would not go back to being a police officer.
On Monday, a grand jury decided not to indict Wilson, a white police officer who shot and killed African-American teenager Michael Brown in the St. Louis suburb of Ferguson on August 9.
Brown's killing sparked weeks of often-violent protests in the city and related demonstrations across the country. A new wave of protests erupted on Monday following the grand jury's decision.
