12 gauge buck will open any lock.What was reported today is that the door was a heavy steel door that opened outward with a lock on it. LEO did not have the equipment on hand to breach the door until a TX game warden showed up with a crow bar and hammer. The custodian showed up with a key at the same time.
This is the current story of why they couldn’t breach the door.
Personally, I would think from a security standpoint that the local Leo and sheriffs dept should have been issued a master key?
