I doubt the police know any of the details when they make the decision to shut down the highway. Think about it. If they wait five minutes to think about whether it is related or not...the guy is most assuredly gone. A man being shot near an interstate exit is going to have to be presumed to be the sniper until shown otherwise.

Police treating it in a similar fashion per WRLH anchor.

The shooter(s) have proven their IQ is several standard deviations above the police. After 10 shootings, probably the perp is not Goober in a white van. And probably he's not touring America on I-95. The public has so little info, we can't exclude any possibility. However, another Freeper speculated it's an Islamist ring involving multiple shooter/spotter teams, meticulous planning, safe houses and other logistics. The police don't catch him (them) because (he) they shoot, scoot and hide until the coast is clear.
