The King County Sheriff's Office said Friday that it continues to investigate the online threat made earlier this week against students at Skyline High School in Sammamish.
KCSO said dectectives have followed up on every tip and lead from the public, but no suspect has been identified. There have been no additional threats to Skyline or other area schools.
Working in coorperation with the FBI, KCSO investigators traced the online threat to an IP address on a proxy server in Sweden. Such servers, however, are often used to disguise the actual location of the user, so this lead is considered a dead end.
Anyone with relevant information should contact the King County Sheriff's Office call center at (206) 296-3311.
A local student posted a video to Facebook in response to the threat, encouraging people to create an accepting environment. KCSO distributed a link to the video on Friday.
