The video we exclusively obtained shows Franco going outside with a cart, preparing to meet a colleague to bring in supplies for a party the following day.
She props the door with a rock and tells us she brought the cart out to the gate to wait for her coworker.
That's when she heard the crash,
Franco was outside Robb Elementary when the shooter crashed a pickup truck into a ditch nearby.
The footage shows that at 11:36, Miss Franco runs inside and gets her cell phone to call for help in case someone was hurt.
52 seconds later, Franco comes running back inside as the shooter starts firing shots at her and several men.
As she re-enters, you can see she clearly kicks the rock from the door and pulls on it to make sure it closes.
She then rushes to warn other teachers, while on the phone with 911, knocking on doors and screaming that the gunman was heading for campus.
"There is a guy with a gun! Call the office..." she tells another employee.
The 911 dispatcher asked Franco what the shooter was wearing, so at 11:37:20, we see her go back to the door and continue answering questions.
Police have not arrived at 11:38.
News 4 San Antonio and Fox SA obtained exclusive video from the hallway of Robb Elementary.
