Authorities in Detroit have identified the remains of a woman found in an abandoned Detroit house nearly 20 years ago.

Decades after investigators unearthed thousands of human bones and bone fragments on a suspected Indiana serial killer’s property, a renewed quest is playing out in laboratories to solve a long-running mystery: Who were they?

On Aug. 25, 1991, someone called 911 to report a dead body beneath a wooden board at the intersection of the Cross Island and Southern State parkways in southeast Queens, according to the DA’s office. Prosecutors say the woman’s ankles were tied together with a cord.
