Application of combined analysis of radiocarbon and aspartic acid racemization on four teeth collected from homicide case. Three teeth with relatively short enamel laydown times showed no bomb spike-derived ¹⁴C in the enamel. However, the fourth tooth, an upper jaw third molar with a much longer enamel formation period, did and matched atmospheric ¹⁴C levels equating to 1955.0 (green filled square). This indicates a birth date of 1942.0. By adding the average age (red dashed line) estimated from the racemization analysis, the year of death was calculated (red vertical line) to be 1988.8. DOB, date of birth.
