Apparently, from what I have been able to gather, he was at home, got a call late in the evening - went into his office, then left his office at 11:30 p.m., leaving his cell phone and glasses on his desk, and headed northeast to the Philadelphia area, where he had made several non-work-related trips during the past few months. He then drove West on the Turnpike towards Lancaster County, where he was found dead about 5:30 a.m.
He left Baltimore, driving Northeast towards Philadelphia when, instead, he could of just shot up I-83 to York Pa and then over to Ephrata, almost a straight shot. Why the circuitous route?
A direct route from Baltimore to Lancaster County covers about 100 miles and would take under two hours. The route Luna took, however, covered about 135 miles and would have taken about 2 hours.
