Just thought of something regarding control of sound in this scenario, since people seem to be assuming the need to keep the noise partially outside a truck. What if there were two people, one being a driver and the other being a deaf person (shooter) inside a mostly-closed back of a truck, with only a small opening needed for aiming out. Then it wouldn't matter how loud it was, if there is no hearing left to damage. It might even make it easier to concentrate, for all I know.

Fox News was mentioning that they only focused on the truck scenario because one happened to be there at the time. It might turn out that this guy doesn't even have a truck or wasn't even in the truck. They were saying that the police have no proof that this guy was in a truck.

...other being a deaf person (shooter)...

Another Gallaudet University student murderer?

A .223 isn't that loud I don't think (having never shot one) - I mean, not like a .308 or a shotgun or anything. It's only slightly bigger than a .22. A good set of earplugs and/or shooting earmuffs inside of a truck would probably be quite effective in protecting hearing. And shooting out of a small window I imagine would do quite a bit toward sound suppression, not to mention flash (which isn't going to be too visible in daylight anyway), as long as the muzzle is inside of the vehicle.

However in the latest 'tarot card' story they seem to have said they found a flattened area of grass where the perp probably lay in wait for his victim.
