OGDEN -- Authorities have filed charges against a 16-year-old boy accused in a plot to detonate a bomb at a Roy High School.
Police say Joshua Kyler Hoggan, along with 18-year-old Dallin Morgan, planned to bomb an assembly at Roy High.
Both were arrested last week. Morgan has been charged with possession of a weapon of mass destruction.
Prosecutors on Tuesday charged the 16-year-old with the same count in juvenile court, but have filed a motion seeking to try him as an adult.
"The defendant's emotional attitude, pattern of living, environment and home life demonstrate that he has sufficient maturity to appreciate the seriousness of these charges and to be tried as an adult," prosecutors wrote in the motion filed Tuesday in Ogden's 2nd District Court.
Police say the plot was foiled when another student came forward after receiving ominous text messages from one of the suspects hinting at their plan.
