BOTHELL, Wash. - Investigators are searching for clues following a vicious attack on a high school teacher inside his classroom.
KCPQ reports that Cal Pygott was working alone in his wood shop classroom at Bothell High School when he was bashed in the back of the head with an object.
He managed to stumble outside and flag down help before he passed out.
Another staff member at the high school was able to cut the zip tie, allowing him to breathe again.
Pygott is now recovering from his injuries, adding that he plans to be back at school as soon as possible.
Now, investigators are scanning through hours of surveillance footage in hopes of finding the attacker.
"No one has been found and no one know who it could be," said Trey Kubalanza, a student.
Students say they hope it is not a classmate, but officers say it is too early to rule anyone out.
