(AP) — A Utah beauty pageant winner charged with tossing homemade bombs from a vehicle has relinquished her crown.

Kendra McKenzie Gill said she and her friends feel terrible about the incident, but she insists they were just playing a practical joke and never threw the explosives at people.

Gill and three friends were charged last week with four felony counts of possession of an explosive device.

Prosecutors say the 18-year-olds drove around town Aug. 2 and tossed plastic bottles of toilet bowl cleaner and shrapnel at people and property.

Nobody was injured.

Gill topped a slate of nine beauty contestants earlier this summer to become Miss Riverton.

She said knew she’d probably have the title revoked, and wanted to step down before it was taken from her.
