From an article:
People around the country spotted the threat Wednesday night on a website, www.4chan.org, "to go to Wilson High School and shoot people at noon on Thursday," said Portland police spokesman Sgt. Pete Simpson.
The original anonymous post did not identify where the school was located. There are at least 249 schools in the United States with the word "Wilson" in them, 25 of them high schools.
Those 25 high schools are spread across 17 states, plus the District of Columbia.
A friend emailed Brian Chatard, Wilson's principal in Portland, about the threat. He called police. Meanwhile, a tipster in Michigan and police in Long Beach, California, among the many places with Wilson High schools, determined that the person making the threat was using a computer in Southwest Portland.
Based on that information, officers here were able to determine the likely identity of the person who posted the threats.
Early Thursday morning, Portland police -- with the assistance from the Portland Public Schools Director of Security, Wilson High School staff, Youth Services Division officers, and the FBI -- contacted the residents and took an unidentified 17-year-old male into custody without incident.
Officers determined that the teen did not have any firearms or access to firearms and it does not appear that any students were actually at risk.
At this point, the case has been referred to the Juvenile Court.
"Thankfully, this was not a credible threat," said Simpson, "but it's a stark reminder that people do this kind of thing."
