A threat of armed violence at Larkin High School in Elgin appeared on Facebook and Snapchat Monday night. The school will open Tuesday, a school district official said, and police and school officials are looking into the source of the threat.
Elgin police spokeswoman Kristie Hilton said there would be a police presence at the school but could not comment further on an open investigation.
In a screenshot of the post -- in which some text is already scribbled out by a digital pen -- a message reads, "On march six I will be Shooting up Larkin high school." The circulated image does not include the poster's name.
John Heiderscheidt, Elgin Area School District U-46 district safety coordinator, was aware of the post Monday night. He said the district is following its existing policy for investigating threats against its facilities and is working with police.
