Barbara Rose Precht (née Hess),[3] previously known as Pearl Lady, was an American woman who was found dead in the Ohio River in 2006; she remained unidentified until 2014.

[5][6] Barbara Precht was originally from the wealthy Hess family of Cincinnati, Ohio; her father was the head of the local bar association and her uncle was a judge.

[4] Investigators published reports and various online databases detailed the case but never uncovered solid leads, which resulted in her identity remaining a mystery, along with many others in the United States.

[6] Many amateur sleuths on the Internet expressed possible matches for the decedent, which has generally been a successful way toward identifying the unknown,[10] but did not lead to finding Precht's identity.

[9][11] Precht was identified after her fingerprints were compared to those taken years earlier after she had been arrested in 1986 in Covina, California, for shoplifting groceries, during the period when her family were living under assumed names.
