The Skagit Valley Herald reports 19-year-old Korry Martinson of Sedro-Woolley pleaded guilty to felony harassment in an unusual plea agreement with prosecutors.
If a mental health evaluation indicates he could pose a danger to the community, the plea will remain. But, if the evaluation yields no concerns for future behavior, he could withdraw his felony plea and plead guilty to gross misdemeanor harassment instead.
Martinson made the threat on Facebook on Dec. 14, the same day as the mass school shooting in Newtown, Conn.
The threat was seen by several people, who reported it to the Sedro-Woolley police and the Skagit County Sheriff's Office.
Martinson's mother also was contacted by several callers. When she confronted her son about the posting, he got into an argument with her and took off before police arrived at his home.
Martinson finally turned himself in a few days later, when a friend brought him to the Sedro-Woolley police station. He was placed under arrest and booked into the Skagit County Jail for investigation of felony harassment.
A screenshot of the Facebook threat allegedly posted by Martinson said:
"Okay, so about that shooting of the little kids.
"I would personally like to thank the man who did this. You will (be) looked upon as a hero in my eyes. You have rid the world of 20 future s------- and w-----.
"I say good riddance, and that we need more people like you. It's the government's fault as to why these things happen.
"If this causes our gun laws to be taken away, to the point as to where I cannot own a gun, I will personally get my sawed off double barreled shotgun and my AK-47 and go shoot up every school within a 100-mile radius of my current location."
Lt. Lin Tucker of the Sedro-Woolley Police Department said the threats shook up many people in the community.
