Guilford police are investigating after getting a tip about a "kill list" through the Sandy Hook Say Something app last week.
The police department said they received the tip overnight on Jan. 11. It indicated that a Guilford High School student had a "kill list."
Authorities received a similar tip the following day, and police said that prompted further investigation.
According to police, it was determined that the list was made in 2022, and the student in question "did not have any means or the ability to perpetrate any such act."
