The reason he is REVISITING The Gate of Heaven is BECAUSE he lives nearby in Wheaton...he is most likely on a bicycle and is willing to peddle a few milesa to and from the scene of the crime...OHHH also in Montgomery County...the buses there are equipped to TRANSPORT bicycles....so...chances are he "hops" a ride near the new crime scene...takes his bike with him....fires off a shot...hops on his bike and a few miles away HOPS back on a BUS. MAYBE he shot the bus driver today BECAUSE he was paranoid...felt that maybe the bus driver was "observant"...maybe the bus driver was "rubbed out"... what do you think AP?
