(CNN)A federal investigation has not found enough evidence to charge Darren Wilson for depriving Michael Brown of his civil rights, according to multiple sources familiar with the probe. This would be the second time the former police officer has avoided standing trial in the black teen's fatal shooting last summer in Ferguson, Missouri. The FBI joined local officials in interviewing more than 200 people -- and looked at much the same evidence -- as a St. Louis County grand jury that decided in November not to indict Wilson, who is white, on any charges in Brown's death. That federal law enforcement agency has now completed its investigation into the August shooting and sent its findings to the Justice Department, a law enforcement official and a separate U.S. official said Wednesday.

A grand jury decided against state charges for ex-Ferguson police Officer Darren Wilson

It all stems from Michael Brown's fatal shooting, which stirred up large, emotional protests
Based on that probe, @placeholder prosecutors won't recommend civil rights charges against Wilson because there is not sufficient evidence to support them, a U.S. official told CNN.
