The common denominator that every, single one of these mass shootings share:
It was not immediately clear how many people may have been injured, but at least two witnesses told NBCDFW that they saw people hurt.
Hundreds of people were evacuated and were being kept in a parking lot across from the mall, waiting for someone to pick them up or being allowed back to their cars.
Witnesses described moments of terror as they sheltered inside stores for as long as an hour before they were evacuated.
The shooting drew a large law enforcement presence from several federal, state and local agencies.
In a written statement, Gov. Greg Abbott said he was aware of the shooting and offering the state’s assistance in investigating the shooting.
