Disturbing Note Found In School Stabbing Suspect's Locker


PITTSBURGH (AP) -- Police say the Pennsylvania boy accused of stabbing 21 high school classmates wrote a note saying he couldn't wait to see the "helpless looks" on students' faces when they realize "their precious lives are going to be taken."

Police say the note was found in Alex Hribal's locker. They say it was dated April 6, three days before the rampage at Franklin Regional High School near Pittsburgh.

The details about the note are contained in a new criminal complaint filed Friday against Hribal that increases the number of attempted homicide charges he faces to 21, up from four.

The complaint also reveals what Hribal allegedly told the vice principal who tackled him: "My work is not done, I have more people to kill."

Two of the 21 wounded students remain hospitalized.
