Utah Beauty Queen Kendra Mckenzie Gill Accused of Throwing Homemade Bombs

A teen beauty queen from Utah is under arrest after police accused her and three others of throwing homemade bombs in an affluent neighborhood in Riverton.

Kendra McKenzie Gill, 18, the reigning Miss Riverton and a contestant in the upcoming Miss Utah pageant, and three other teens allegedly made crude bombs by filling plastic water bottles with water, aluminum foil and household chemicals. They threw the devices at homes, police said.

Nine incidents were reported, although police say nobody was injured.

All four suspects were arrested Saturday morning and booked on suspicion of detonating an incendiary device.

Along with Gill, the others arrested were John Patrick Reagh, Shanna Marie Smith and Bryce Christopher Stone.

They were each held on $50,000 bond and released Sunday night.

No return court date has been set.

Capt. Clint Mecham of the Unified Fire Authority said residents reported hearing explosions in their neighborhood late Friday night into early Saturday morning.

He said the alleged incidents went way beyond a teenage prank.

"These devices are extremely dangerous," Mecham said. "They can cause property damage and bodily harm. They can even be deadly in some cases."

Nichelle Spencer, a friend of the suspects, said she was surprised to hear about their alleged involvement in the incidents.

"I wouldn't expect them, they are really good people," Spencer told ABC News.

Gill's arrest could scuttle her hopes of ever becoming Miss Utah.

Gill and the Miss Utah pageant declined to comment.

ABC News was unable to reach the other three suspects for comment, and it wasn't immediately clear whether they had attorneys.
