Police credit a 16-year-old Utah girl for leading them to the two teenagers who were allegedly planning to set off bomb at Roy High School and escape in a stolen plane. Sophomore Bailey Gerhardt received a text message from one of the suspects that read: "If I told you to stay home on a certain day, would you?" She reported it to police, who launched an investigation, according to the Salt Lake Tribune. Dallin Morgan, 18, and the 16-year-old boy who confessed were pulled out of school Wednesday and arrested after authorities learned of the plot, police in Roy, Utah, said. The students prepared by logging hundreds of hours on flight simulator software on their home computers. The juvenile told investigators he was so "fascinated" by the 1999 Columbine High School massacre that he visited the Littleton, Colo., school and interviewed the principal about the shootings that killed 13 people.
