Answer: They have a hole in their car for end of rifle and didn't drive a white truck. They blended in.
There's one thing that doesn't make sense to me about this hole in the trunk. Okay, how could someone take aim with a scope on the rifle through a hole in the trunk? Have they said how big this hole is? Hasn't it been confirmed the shooting was done from the wooded areas?
My car, a small 1992 Toyota, has a fold down rear seat with an opening into the trunk.
maybe somebody's got this already, but ...
where's the gas spout on that make of chevy ?
it'd be a pretty simple matter to cut an ample hole behind the license plate,
then mount the plate to spring-loaded bar, etc to get it out of the way.
similar thing could be done to one of the taillight assemblies ...
this was a coffee break post
nothing further - please move along ...
