A 13-year-old Rikki Howard and her 10-year-old half-sister Casie Hicks were riding on the rolling hills of Arizona in a three-wheeled ATV and were seriously injured Saturday in an ATV accident, when their vehicle suddenly tore down a 125-foot mine shaft. The Arizona hilly countryside apparently obscured the opening to the mineshaft, and the girls’ vehicle fell right into it.
According to media reports, the girls were found in the abandoned mine shaft once one of them responded to their father’s shouting. One of the sisters tragically did not survive the fall.
The two girls were missing for approximately twelve hours before a search was initiated. According to Arizona authorities, Casie Hicks was flown to nearby University Medical Center in Las Vegas, where she remains in critical condition.
