Tammy Sue Lynn Passineau was 18 when she disappeared from the West Water Street area of Syracuse, New York, on April 11, 2004. She had a history of mental illness and required regular medication; family members say she moved frequently and was described as a drifter, which delayed reporting her missing until May 2004 after she failed to cash social services checks or refill prescriptions. She was a mother; her young son was in foster care at the time she went missing.

Investigators later linked serial killer Nicholas Wiley to Tammy’s case. Reports say Wiley confessed to killing a red-haired girl named Tammy, and Tammy’s DNA was connected to blood found on Wiley’s belongings. Tammy’s body has not been recovered, and her family continues to seek closure. The case remains open.
