Police arrested 18 year old beauty pageant winner Kendra Gill and 3 other teens on suspicion of detonating incendiary devices during a bomb-throwing spree in Riverton, UT.

Unified Fire Authority Captain Clint Mecham told Reuters "This wasn't just like kids blowing up a mailbox".

Police received numerous calls late on Friday about the sound of explosions or gunshots in a Riverton neighborhood where investigators later found remnants of bombs constructed from household chemicals, aluminum foil and plastic water bottles.

Residents of the neighborhood and other areas of Riverton reported that the devices were being thrown from a dark-colored car, according to arrest records.

A resident of one of the homes targeted told investigators her former boyfriend, Bryce Stone, owned a car matching that description. Stone later told investigators he had spent the evening "‘pranking' with fireworks with friends," records show.

Gill, Stone and two other 18-year-olds were arrested on suspicion of 10 felony counts of setting off explosives, according to booking documents. They were each released on $50,000 bail on Sunday, jail officials said.

No one was injured by the blasts, which caused minor property damage, but the explosives could have caused severe harm from acid burns or shrapnel, Mecham said.

Officials with the Miss Utah Scholarship Pageant said they have taken no action since no official charges have been filed against Gill. They go onto say that they hope that this will just blow over; I am not sure how I feel about that and wonder if the suspect was not a 'beauty queen' would they still have the same position? Comments?
