Investigators with the King County Sheriff’s Office and the FBI reached a dead end when trying to trace the IP address of a person who posted an online threat that closed Skyline High School in Sammamish on Thursday.
The school was closed after someone posted a threat about bringing a gun to school, firing it and then committing suicide. The threat circulated on social-media sites on Wednesday.
The school district issued a statement Wednesday night saying it was closing the school Thursday out of an abundance of caution for the safety of students and staff.
A spokeswoman for the sheriff’s office said on Friday that detectives have followed every tip and lead, conducted interviews and traced the IP address. They reached a dead end, said Sgt. Jessica Sullivan, when the IP address was traced to a proxy server in Sweden.
Proxy servers are commonly used to disguise true IP addresses, she said.
Sullivan said detectives were not able to verify that the threat came from a student or anyone in the area. She said there have been no additional threats to Skyline or any other local school.
She also recommended a video on a social-media site in which a Skyline student urges his fellow schoolmates to handle the situation by “being nice” to others.
Anyone with information about the threat is urged to call the King County Sheriff’s Office call center at 206-296-3311.
