OGDEN -- The Weber County Attorney's Office has filed a motion in 2nd District Juvenile Court to certify 16-year-old Joshua Kyler Hoggan as an adult for what officials say was his role in plotting to set off a bomb at Roy High School.
Hoggan and another Roy High student, Dallin Morgan, 18, were arrested Jan. 25 after police and school authorities uncovered what they say was a plot to set off a bomb during a school assembly, steal an airplane and fly out of the country.
Hoggan would normally be tried in juvenile court, which is less public and only has jurisdiction until he turns 18.
Trying him as an adult would mean he would go through adult court and face adult penalties.
Authorities were tipped off by several Roy High students who said they received troubling text messages from Hoggan.
Roy police say they have recovered explosive materials, as well as plans and details of the alleged plot.
In the motion filed Tuesday, Deputy Weber County Attorney Letitia Toombs argues that Hoggan should be tried as an adult because:
* The offenses were "especially serious given the fact that the offense was directed against the entire student body and staff of Roy High School as well as a threat of extensive property damage."
* The offense was committed "in an aggressive, violent, premeditated and willful manner."
* The offense was against more than one person.
* Hoggan's emotional attitude, patterns of living, environment and home life show he has "sufficient maturity to appreciate the seriousness of these charges and to be tried as an adult."
* Because Morgan is an adult, it would be better to have both suspects tried in the same court.
* The threat was against a school.
In addition to the motion to certify, the Weber County Attorney filed an information document saying Hoggan was to be charged with one count of use of a weapon of mass destruction, a first-degree felony.
Police say Hoggan made extensive preparations for the crime, including using computer flight-simulator games to learn to pilot a plane and, last year, going to Colorado to interview the principal of Columbine High School.
Columbine was the scene of a 1999 shooting rampage by two students who killed 12 students and one teacher before committing suicide.
