The body of a 16-year-old Caucasian girl was found in a Caledonia, Livingston County, New York, cornfield on November 10, 1979. Found fully clothed and with pockets turned inside out, she had been shot once in the head and once in the back with a .38 caliber weapon. Heavy rains that night washed away much potential forensic evidence, severely hampering the original investigation.

Known for decades as Caledonia Jane Doe or Cali Doe, she was buried as Unidentified Girl in Greenmount Cemetery in Dansville. Leads over the years included false confessions by Henry Lee Lucas and a possible connection to Christopher Wilder; a man seen with her at a diner shortly before her death was never identified. In January 2015 DNA testing matched the body to Tammy Jo Alexander after a missing person report was finally filed following an inquiry by a high school friend.

The murder remains unsolved and the investigation is active; the FBI is offering a reward for information leading to an arrest and conviction. If anyone knew Tammy Jo Alexander, saw her in the days before November 10, 1979, or has information about the man seen with her, please come forward.
