Just three have been confirmed to have left the building.
However the “strength” of what they are bringing into this situation is really strong...as is the duration....it would indicate to me there’s much to be concerned with we aren’t privy to.
The video replay they’ve shown was clear the three escaped. The employee came out the fire door and the two customers bolted out the front door.
Those big trucks that just rolled up are definitely a reason for concern. Prayers going hard and fast for the rest of the hostages and everyone else in the vicinity.
