Jonathan Pentland, a U.S. Army  sergeant first class, is being investigated after he was seen pushing, threatening and yelling at a young Black man in a South Carolina neighborhood. Officials launched an investigation after a video of the incident surfaced on Facebook on Monday, Heavy reported . Social media users contributed to the investigation by identifying the sergeant on Tuesday.
