FARMINGTON -- An 18-year-old man who set off several "Works" bombs at Bountiful High School entered not guilty pleas Monday.
Chris Andrew Perry, who is a Bountiful High School junior, appeared in 2nd District Court. He entered the not-guilty pleas to three counts of possession of an explosive device, second-degree felonies. Another hearing is set for May 7.
Second-degree felonies carry the possible sentence of 1 to 15 years in Utah State Prison.
Perry is being held in Davis County Jail in lieu of $20,000 bail.
Bountiful police said Perry and a 16-year-old sophomore girl set off four incendiary devices April 11.
One of those devices was set off at the school, which caused school officials to put the school into lock-down for about 90 minutes, while police searched the building and the school grounds for more devices.
Another device was set off at a nearby church, which was also close to Millcreek Junior High. That school was also put into lock-down.
Police found two more explosives near the school, officers said.
One explosive was found at an apartment complex and another was found in a Bountiful resident's home, police said.
The devices were made from toilet bowl cleaner and aluminum foil, officials said.
No one was hurt, and there was no damage.
The 16-year-old girl is facing charges out of 2nd District Juvenile Court.
