The search warrant materials, including a detailed affidavit by state police Trooper Robert LaBarge, describe how Ritzer was seen speaking with another teacher in the hallway at 2:30 p.m., before returning to room A209.
Less than 20 minutes later, she left the classroom and walked to a student bathroom.
What the cameras saw
Chism is seen on surveillance walking out into the hall, back into the classroom, and then back out, this time wearing a hood over his head and putting on gloves. He walked into the bathroom a minute after Ritzer had entered.
It’s not known what transpired inside the restroom, where there are no cameras. But 11 minutes after Chism was seen entering the bathroom, another student walked in. She later told investigators that she saw a person with a bare, dark-colored “butt” leaning over and thought someone was changing clothing, so she backed out.
A minute later, at 3:07 p.m., Chism is seen in the video walking out, again wearing a hood.
Cameras around the school were watching as Chism walked toward the “B” wing of the school, then down a set of stairs and back into the “A” wing, to the student parking lot sidewalk.
Two minutes later, Chism walked back inside, wearing a white T-shirt, jeans and sneakers. He ran down a hallway toward the “D” wing, and back up to the second floor, then back into Ritzer’s classroom. A minute later he left wearing a red hooded sweatshirt. He was also carrying a backpack and two other bags, black and purple.
Five minutes later, the video showed Chism pulling a recycling barrel into the same bathroom. When he left the bathroom, he was wearing yet another outfit, a white T-shirt and now, a black ski mask, which at some point he pulled up onto his forehead while leaving the school through the “A” wing, pulling the recycling barrel.
