"I’m on it, Boss." Tony called as he started running from the room. Once he got back up to their desks he quickly pulled up train schedules. When the others walked in he spoke up. "The only train in the area is an Amtrak. It left DC at... 1620 and arrived Lorton 1730. Average speed of 65 miles an hour. Now, we know it passed our dirtbag at 1706, right?" He asked rhetorically. "So he should be around here, 7 miles outside of Lorton." Tony zoomed in on the location. "There’s an abandoned train maintenance yard about half-mile north."
