SALT LAKE CITY -- Prosecutors are filing charges of bomb possession against a woman recently crowned Miss Riverton.
Kendra McKenzie Gill was arrested last weekend with three accomplices who face the same set of four felony charges.
Prosecutor Blake Nakamura tells The Associated Press 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. She showed off years of piano training with a Scott Joplin number and took home a $2,000 scholarship.
