Fox News is reported a man is in handcuffs, but folks IT IS UNKNOWN IF THIS SUBJECT IS RELATED TO THIS CASE. At this time, not enough info.
How long did it take them to get out the description of the suspect? They knew the minute it happened...
expect many non-associated arrests and detentions after this. They will be searching the area ID possible suspects. In that area, I’d bet 10% of the population have warrants from other crimes.
