On April 22, 1981, Flesher’s body was found in a covered well in Chesapeake. Investigators said she could have been in the well for up to two years. Flesher was found strangled.

Investigators said on Monday that technology improvements in forensic genealogy and DNA samples from family members confirmed the identity. Nonprofit organization DNA Doe Project, helped solve the mystery.
