A day after a mass shooting that killed at least 17 people at Marjory Stoneman Douglas High School in Parkland, Florida, a student Thursday talked about her friend’s face-to-face encounter with the shooter.

Appearing on “The Laura Ingraham Show,” Addison Jost said her friend saw accused shooter Nikolas Cruz putting together his AR-15 rifle in the bathroom.

Jost said her friend told her Cruz cocked the weapon and pointed it at him.

“He turned to Chris, and he said, ‘You should run. I would run if I were you,'” she said.

Jost said her friend immediately ran to the nearest security guard, Aaron Feis, who also was an assistant football coach at the school.

She said Feis responded immediately.

“So he was the first victim from what I can see,” she said. “And, you know, he definitely was making an effort to protect his students. He took his job so seriously. We all know that he was definitely one of our top security guards.”

Critically wounded, Feis died early Thursday.

Jost suggested the rampage was foreseeable. Cruz, who had been expelled, recently lost his mother and her husband, who had adopted him. In addition, something Jost did not mention: BuzzFeed reported that a Mississippi bail bondsman noticed that a YouTube user named Nikolas Cruz left a comment that he was “going to be a professional school shooter” and emailed a screen shot of it to the FBI.

“Of course I’m surprised, but you know, it seems more fitting when you get the whole picture of his upbringing and the fact that his family life wasn’t stable,” Jost said.

Jost said she and her fellow students in another building did not know what was going on for at least 30 minutes.

“We actually did not even recognize that it was gunshots,” she said “As I said before, the shots were so muffled through both the walls of the 1200 building and the walls of my building, the 1300 building, that we thought that it was blanks. We thought, ‘OK, this is just some crazy simulation, and they’re just making it very extreme.'”
