Federal investigators were digging Wednesday into the background of a Georgia man who officials say fatally stabbed a Pentagon police officer at a transit station outside the building before being shot and killed himself. The Pentagon Force Protection Agency identified the slain officer as George Gonzalez, a New York native and Army veteran who served in Iraq and joined the police force three years ago. He died after being attacked Tuesday morning on a bus platform outside the Pentagon. The burst of violence temporarily placed the U.S. military headquarters on lockdown and jangled the nerves of a region already primed to be on high alert for violence and potential intruders outside federal government buildings. The FBI was leading the investigation into the violence and the suspect, identified by multiple law enforcement officials as Austin William Lanz, 27, of Georgia. The authorities were examining Lanz’s background, including his criminal history, jail records, financial information and any online accounts as they tried to identify a potential motive for the attack, a law enforcement official said.
