A Pentagon police officer was on patrol just before 11 a.m. Monday when he saw Matthew Dmitri Richardson, 19, of Fayetteville, attempting to light on fire a piece of fabric that had been inserted into the gas tank of a 2016 Land Rover, according to the U.S. Attorney’s Office in Eastern Virginia.
When the officer confronted Richardson, he said he was going to “blow this vehicle up” and “himself,” court documents say. Richardson then sprinted away from the officer, but was caught a short time later, according to the court documents.
