The Unified Fire Authority says calls started coming late Friday night of loud explosions around the Riverton area.
Investigators quickly determined those explosions were from chemical reaction bombs made from household items.
Early Saturday morning, Kendra Gill, Miss Riverton 2013, Shanna Smith, Bryce Stone and John Reagh were arrested on ten, class one felony charges.
"These kind of devices can damage property, they can maim and kill individuals if they come in close proximity to them. And apparently these individuals were throwing them at various people and property throughout Riverton,” says Captain Clint Mecham, of the Unified Fire Authority.
Unified Fire says there were about ten separate incidents Friday night into Saturday morning, but no one was injured.
The case has been turned over to the district attorneys office for review, but Gill could face further consequences.
"Most definitely she should not keep her title in my opinion," said Gretchen Jensen, host of Good Things Utah and former Miss USA. "Because you're not the epitome of what that role model needs to be. When you get right down to it, you are a good will ambassador. You are an ambassador to your city, which means you represent everybody there."
