An Elementary Murder is a case featured in Criminal Case, appearing as the fortieth case of the game as well as the city of Grimsborough. It takes place at the University, a district based in Grimsborough.
Upon Ramirez's report of a murder happened in Grimsborough Elementary School, the player and Jones rushed there and collected the body of au pair Irina Nemovska, who was found with her throat slit in a classroom. The killer turned out to be a teacher named Jenny Honeycomb.
Jenny was from a social circle which forbade people from revealing any LGBT relationship in any form or fashion. In court, Jenny admitted that she was in a closeted LGBT relationship with Irina. Irina wanted to make their relationship public but Jenny was scared of the repercussions this would have on her. On the day of Irina's death, Jenny had asked Irina to come over in her classroom during recess where she had brought a gun hidden in a teddy bear with her to threaten Irina so that she could end the discreet LGBT relationship since she believed that Irina had betrayed her feelings for Jenny in front of her children and thought by threatening her, Irina would leave Grimsborough. Jenny was not planning to shoot at her but near enough so that she would be scared, but the gun was broken. Irina, thinking Jenny really wanted to kill her, then jumped at her; Jenny tried to fend her off with her inhaler but it only made Irina fight harder. As Irina pinned Jenny to a wall, Jenny grabbed a pair of child's scissors from one of the desks and slashed the victim to death. Judge Hall sentenced Jenny to life in prison.
The passing of "Sarah's Reeree" (Irina the au pair) would change the lives of the Mills family forever, but eventually the Mills would resolve all their differences to become a functional family once more, but at the expense of the media grabbing hold of the serial killer controversy that was first mentioned after a murder investigation during the Spring Break—a feat which prompted Ramirez to have Jones and the player look at the newspaper with The Rorschach Reaper as the cover story.
