Miss Riverton, who was arrested last week for allegedly throwing homemade bombs, has been charged along with three others with multiple felonies.
Kendra McKenzie Gill, 18, was charged Friday with four second-degree felony counts of possession of an explosive device. She is to appear in 3rd District Court in West Jordan on Aug. 26.
Her 18-year-old co-defendants Bryce Christopher Stone, Shanna Smith and John Reagh were given the same charges. All four remain free pending court appearances.
