He is driver because:

No public transit would get to so many areas so fast on multiple shooting days.

Taxis keep records. A face is attached to a fare.

Bike: 160 miles as a standout?

Ok, I'll concede to the fact that he was a driver on the multiple shooting day - I believe there was just one day of multiple kills. FWIW, some days ago (all this is starting to run together for me) a freeper's friend's daughter was jogging near the Home Depot (FBI analyst) scene and saw a man riding a bicycle with a rifle barrel sticking out of his backpack. I believe the poster mentioned the jogger went to the police with this information.
