Investigators used
carbon dating to pinpoint the years of the remains. The bodies were initially thought to be children, with one between the ages of 3 to 5 and the other between the ages 4 to 9. The bodies were also thought to have been buried 15 to 20 years ago.
The first carbon dating tests through Miamis Beta Analytic Incorporated in May dated one body between 1436-1624 and the other from 1445-1632. Hollinshead said he opted for a second opinion and had the remains tested at the University of Arizona in June. Their testing determined the remains of one body to have been from 1436-1522 and the other from 1445-1524. The sexes of the remains were undetermined.
Though inconclusive, testing estimated one body was of a 20-year-old while the other remains were estimated to be of a 10- to 15-year-old. Homicide was ruled out.
