BOTHELL, Wash. -- A Washington wood shop teacher found zip-tied and injured in his classroom earlier this year now admits he staged the crime scene and made up the story, police said in a news conference.
In May, news of the alleged violent attack shook the residents of Bothell. Concerned Bothell High School students wore blue the following Monday and signed a large banner to show support for the popular teacher, 63-year-old Calvin Pygott.
On Tuesday, however, police revealed Pygott had taken a polygraph test that told a different story, according to KCPQ.
After seeing signs that Pygott was not telling the truth, police said they gave him the opportunity to give another statement and he eventually confessed to making up the story.
Investigators also noted in the news conference that there was no suspect in the surveillance video at the school. There were many inconsistencies in Pygott's story from the beginning of the investigation, they said.
Pygott could now face charges for obstruction and giving false statements.
In May, Pygott was found inside his Bothell High School wood shop classroom after classes with an injury to the back of the head and a zip-tie around his neck.
School was canceled for a day while police investigated and extra security patrolled the school grounds as a precaution.
