Teen speaks out after tipping police off to Mariemont HS shooting plot

"He said that if I told anyone about it, he would kill me as fast as possible." That's what Boom Swallen says he was told by another student at Mariemont High School after that teen told Boom of his alleged school shooting plans. Despite the threat to his own safety, the 15-year-old told his father, Zach Swallen, about the threat, allowing police to thwart the accused student.
