A Northern California teenager accused of setting off two pipe bombs at his former high school in a plot to kill three former teachers who gave him bad grades has been found guilty of attempted murder and weapons charges.
Jurors on Monday found 18-year-old Alex Youshock guilty on five of the seven felony charges he faced in the 2009 pipe-bombing at Hillsdale High School in San Mateo.
The teen managed to set off two pipe bombs before being tackled by a teacher. Authorities found him wearing a tactical vest and armed with 10 pipe bombs, a chain saw and a sword.
Jurors are still deliberating on two other attempted murder counts.
After the final verdicts are in, they will have to decide whether Youshock was sane while committing the crimes.
