A teacher in one of the hardest-hit Marjory Stoneman Douglas High School classrooms says her plan to stop the gunman if he walked in was to tell him: “I love you,” according to a report published Wednesday.

Ivy Schamis was teaching her junior and senior students about the Holocaust inside Room 1214 at the Parkland, Fla., school, when Nikolas Cruz loaded his AR-15 rifle in a stairwell, and in about six minutes, killed 17 people while shooting up three classrooms from their doorways.

Almost a quarter of Schamis’ history class was hit, with two students killed and four injured.

“On that day, the lessons of the Holocaust came alive,” Schamis, 54, told The New York Times. “We saw hate firsthand.”

As the Valentine’s Day slaughter unfolded, Schamis, who has taught history for four years, thought to herself that if the gunman entered her classroom she decided she was, “going to stand up and say ‘I love you.’”

“I thought to myself, how can he continue shooting while someone is saying, ‘I love you?’” she told the paper.

Moments before gunfire sprayed her class, Schamis was asking her students if any of them knew who Adi Dassler was.

Nicholas Dworet, 17, raised his hand and rightly answered, “The founder of Adidas” when a shot fatally hit him.

“I was just so excited because he knew that answer. And that is when the first shots rang out,” Schamis told the paper, tears welling in her eyes. “I later told his mother that he was my star student that day.”

Students started crawling on the floor in a panic, as Cruz began firing through their classroom door, shattering the pane.

“I could hear the shots behind me and screaming everywhere,” said 18-year-old Samantha Fuentes. “I threw myself on the floor and started crawling toward the other kids.”

One group grabbed a laptop cabinet podium and file cabinet to make a barricade. They also grabbed books from the bookshelf for protection.

Schamis told the paper she is still haunted by one question a student asked her as the massacre happened: “Mrs. Schamis, are we going to die today?”

“I looked in his eyes and just said, ‘No. Not today,’” she said.

As Cruz turned his attention to Room 1216, an English class, students in 1214 braced for his return and observed their classroom, strewn with toppled desks, blood and glass. Dworet and another student, Helena Ramsay, lay dead next to each other.

Kaitlyn Jesionowski, 18, told the paper she grabbed Helena’s hands, telling her over and over, “It’s going to be OK.”

“I didn’t want her to be alone,” she said.

In the 90 days since the shooting, the students who were in Room 1214 have found solace in a text-messaging group where they talk about their fear and grief.

“First we were students. Then survivors. Now family,” said 18-year-old senior Daniel Zaphrany about the group.
