Law enforcement officials say a group of fourth-grade students allegedly talked about trying to kill their teacher with hand sanitizer because she was mean to them, but concerned parents and a school board member foiled the plot.

The alleged incident happened in December just before winter break, and according to the police report, three students between ages 9 and 10 at Elba Elementary School, located between Rochester and Buffalo, were involved.

Their plan was to expose a teacher to anti-bacterial products because she is highly allergic to them.

The report, provided by the Genesee County Sheriff’s Department, said, “the suspects made comments to other students that they were going to kill (the teacher) by putting antibacterial products around the classroom.”
