A news reader was on the phone with a store owner at the mall who related that he was told by a witness that the shooter was on the second level firing down into the food court with a shotgun and that the shooter is one of the three people reported dead, some saying by their own hand.
Per the Baltimore County scanner, they are having people shelter in place, then sending the people to secure locations (in the mall) to shelter in place until the cops clear the people to leave. They are still searching the mall.
A shotgun..That person was just following Joe Biden’s advice
