SALT LAKE CITY — Prosecutors are filing charges of bomb possession against a recently crowned Utah beauty pageant winner.

Kendra McKenzie Gill, who was crowned Miss Riverton, was arrested last weekend with three accomplices who face the same set of four felony charges.

Prosecutor Blake Nakamura tells The Associated Press that the charges were submitted to 3rd District Court late Friday.

The 18-year-olds were arrested Saturday after driving around neighborhoods and allegedly tossing plastic bottles of caustic chemicals and shrapnel at people they knew.

Nakamura says it may have been a prank and nobody was injured, but prosecutors are taking the case seriously. Each felony charge is punishable by 1-15 years in prison.

Gill topped a slate of nine beauty contestants earlier this summer in the Salt Lake City suburb.
