On February 24th, a Pentagon police officer found Matthew Richardson trying to light a Land Rover on fire with a lighter as well as a cloth stuffed into the gasoline tank. Richardson said he was going to blow up the vehicle as well as himself. After the officer attempted to detain the 19-year-old, Richardson fled and jumped over a fence into the Arlington National Cemetery. He was found near the Arlington House and was arrested. In his pockets were a lighter, gloves, and a document relating to a previous assault on an Arlington police officer. The soldier and Richardson did not know each other.
