An alert mom called police after discovering her son's journal. In the journal, the 17 year old wrote of his plan to attack College Place High School next year on the anniversary of the Columbine attack, April 20th. Cops arrested the teenager and he was booked into the Walla Walla Juvenile Justice Center for Felony Harassment and Threats. You can imagine how hard it was for the mom, but she knew it was the right thing to do and was praised by the Chief.
