At Kamikita Elementary School in Osaka, teachers were passing out with pastries in their mouths and waking up two days later in the hospital. These strange incidents were happening about once a year at the elementary school, and no one knew why.

As it turns out, these school teachers were being drugged with sleeping medication by 60-year-old teaching assistant Atsuko Nakaoka. Nakaoka’s method was pure genius—she inserted the drugs into snacks, like cream puffs, which she then gave to the teachers.

“The earliest incident may have happened to a 64-year-old teacher back at the end of April, 2005. During a meeting, she suddenly passed out face-down on her desk with a snack she was eating protruding out of her mouth. She was taken to the hospital and awoke 45 hours later,” reports Rocket News 24.

Two months later, the same woman collapsed at a meeting just after eating a snack. When the woman was taken to a hospital, doctors examined her and found that “her brain activity suggested that she had taken a large amount of sleep-inducing drugs.” Atsuko Nakaoka went with the woman she had drugged to the hospital to keep her company (shudder).

On June 1st of last year, during a staff meeting, cream puffs were distributed to the five or six teachers in attendance. When one 40-year-old female teacher bit into the cream puff, she suddenlt fell unconscious and had to be taken to hospital. It was learned that she had ingested a severe dose of brotizolam, a sedative used to treat insomnia. Nakaoka had struck again.

In August of this year, Nakaoka’s involvement in the drugging came to light. “On November 14, Osaka Police announced that Nakaoka is being charged with injury for the drugging as well as destruction of property for the messages she scrawled on her coworker’s possessions and cubbyhole,” reports Rocket News 24.

Nakaoka admitted to the charges saying,

“I had a problem with their teaching methods. It really got to me, and I thought it would be better if they weren’t around.”

So next time your coworker cuts in front of you to use the coffee machine, just remember: there’s always cream puffs.
