ROY -- About 13 months ago, Roy High School student Megan Wehrman told Principal Gina Butters in secret of concerns that two fellow students might be plotting to blow up the school and the 1,500 students inside.
Wednesday night, Wehrman, now 18, finally shares her story with the world.
"The Path to Violence," part of an After Newtown initiative at PBS, plays at 9 p.m. on KUED Channel 7.
The hourlong documentary begins with the story of Wehrman, now a graduate, and her decision to come forward when other students with similar information did not.
Also interviewed for the program segment were Butters, Roy Police Chief Greg Whinham and Roy High School resource officer Tom Tomlinson. In a nonfinal version of the show provided to the media, all of the Roy High content seemed to be contained in the first 15 minutes of the program.
"I viewed it as very favorable," said Butters, who previewed the Roy High School segment.
"It said what it needed to say. It touched on the right views and people, I think. I was quite pleased. It reflects greatly on the Royal community."
Wehrman spoke to filmmakers about her friendship with one of the boys, and of worrisome texts. Both boys were bullied, Wehrman said, but the texts seemed to go beyond venting and hinted at a concrete plan for mass destruction.
Butters tells of Wehrman's approaching her and asking to talk, confidentially, and of the texts that caused the principal to immediately call in the Roy Police Department.
Officers found no explosives but learned that the boys did have a detailed plan and access to guns, and that one boy followed mass school shootings in the news and had taken a secret trip to Colorado's Columbine High School, site of a 1999 mass shooting by two students.
The Roy High boys, who were then 16 and 18, each served jail or detention time, now completed. Whinham told filmmakers that both boys seem to be on a better life path.
"The Path to Violence" also features interviews with other school and law enforcement professionals from outside Utah.
"The documentary brings the conversation of balancing school safety with civil liberties to the forefront of viewers' minds," said Jason Williams, executive producer.
According to the documentary, more than 120 school assaults have been thwarted in the past 10 years.
Butters said film director Kathy Slobogin has promised the school a copy of the program, and after assessment, that copy may be made available to teachers to share with their students as part of course work.
Interest in when the documentary airs has been high, Butters said, and finding the listing was tricky because the documentary was unnamed at the time the production crew visited the school.
"The kids were very aware when there was a film crew here," she said.
"I know a lot of people are interested and will be watching. The biggest thing I would like to come out of it is for the young lady (Wehrman) to get the credit she deserves. She is our hero."
