A man took to Instagram Live and claimed to have killed the Grammy-nominated rapper in front of who he says was Nipsey's daughter Sunday afternoon in the Crenshaw neighborhood of Los Angeles. It is not confirmed if Nipsey was killed in front of his daughter, and police are not saying if the Instagram Live video is a credible lead.
