An email sent by a student to the principal and all of the freshmen at Oconomowoc High School prompted a police investigation into possible safety concerns.
The email accused a different student of being a threat and mentioned the fictional character Slender Man.
Police immediately investigated some of the claims in that email and the district says it determined there is no threat to student safety.
The email sent on Wednesday includes many personal details about the student and says the person "...believes she has multiple personalities...is the daughter of slenderman."
Slender Man became well-known in 2014, when two Waukesha County girls said they stabbed their classmate 19 times to please the character.
They both were recently committed to mental health facilities.
In addition to mentioning Slender Man, the Oconomowoc student also claimed that this other student "wanted me to join her and two other girls in a cult-like group called the "Trinity Sisters."
"I didn't find them to be true," said Alexis Zimmerman, a junior at the school.
She says she and many other students weren't concerned about what the email said but were more upset that it even went out.
"I don't think anyone found it as a threat," she said. "It was just, it wasn't something right to say about someone else."
Alexis' mother Nicole Gronitz says the school notified parents about the email, but she too wasn't concerned.
"It really didn't make me think twice about it," she said. "A lot of the stuff has just been kind of fake lately."
District officials would not comment on any disciplinary issues. The full statement from the district is below:
On Wednesday, April 11, an Oconomowoc High School (OHS) student sent a mass email to several staff members and the 9th-grade class. This email contained very detailed accusations and personal information about a classmate.
The OHS administrative team, along with Oconomowoc Police Department and School Resource Officer, Adam Parkhurst, immediately began investigating the claims contained in the email message. Based on that investigation, the District can confirm that there was never a threat to the safety of our students and staff, and the incident was handled as a student matter.
The Oconomowoc Area School District (OASD) will continue to take immediate and significant actions to keep our schools safe, and the safety and security of students and staff remain our top priority.
