You get alot of information bouncing around after a situation like this. Everyone posts bits and pieces of stories you hear.
It’s possible that the reports of a hostage come from callers witnessing the chase.
They see a pickup truck with an armed man in the passenger seat and assume its a guy with a hostage , but it turns out it’s the good-guy chasing the shooter.
That’s true. But if the report was recent, it probably is accurate, as I’m sure they would have sorted that out by now.
