Who Is Austin Lanz? Suspect Identified In Pentagon Transit Center Shooting On 8/3/21 at 9:47 PM EDT Lanz, a 27-year-old Georgia resident, is suspected of having rushed towards a Pentagon police officer before stabbing them in the throat, killing them. Law enforcement officers then shot Lanz, killing him at the scene. Lanz had previously enlisted in the U.S. Marine Corps in October 2012, the Associated Press reported. However, he never earned the title Marine because he was "administratively separated" from the service less than a month later, the Marine Corps said in a statement. Investigators are looking into Lanz's background for evidence of mental illness or political sympathies that might've contributed to his alleged actions.
