Rumor has it that the perp was distracted or nodding off and the hostages gradually scooted down the pew they were sitting on. At some point, the rabbi threw an object at or hit the perp allowing the hostages to get out the nearby exit and run to the Bearcat sitting nearby. FBI breached the door and killed the perp with multiple rounds. Hostages were unharmed.
So I heard.
Good to hear about their bravery. Thanks for the update.
