In the spring of 2004, a 17-year-old White female named Tammy Sue Lynn Passineau vanished from the streets of Syracuse, New York. The young mother, known to be a transient who often moved between residences, was last seen on April 11 in the vicinity of West Water Street. Her family, accustomed to her sometimes erratic lifestyle and struggles with mental illness, did not immediately report her missing. However, as weeks turned into a month with no contact, and her social services checks went uncashed, a profound sense of unease settled in.
The investigation into Tammy's disappearance soon took a dark and sinister turn, intertwining her fate with that of a recently released serial killer. Nicholas Wiley, a Level 3 sex offender with a violent criminal history, had been freed from prison just months before Tammy was last seen. In June 2004, Wiley was arrested in connection with the murders of two other Syracuse women: 22-year-old Hannah Finnerty, who was five months pregnant, and 31-year-old Lottie Thompson. Finnerty's body was discovered in a dumpster, while Thompson was found stabbed to death in her apartment.
During his interrogation, Wiley confessed to the murders of Finnerty and Thompson and made a chilling admission that he had killed others, including a 'red-haired girl named Tammy.' This confession led investigators to connect him to Tammy Passineau's disappearance. A crucial piece of evidence emerged when dried blood found on a box cutter belonging to Wiley was matched to Tammy's DNA. Despite extensive searches, her body was never recovered. Investigators believe Wiley disposed of her remains in the same dumpster where Finnerty's body was found, and that her body was likely incinerated at a county trash-burning facility.
In March 2005, Nicholas Wiley was charged with the second-degree murder of Tammy Passineau. During his trial, he claimed he killed her after a heated argument. In October 2006, a jury found Wiley guilty of the murders of Tammy Passineau, Hannah Finnerty, and Lottie Thompson. He was sentenced to life in prison without the possibility of parole. Though her case is officially considered a presumed homicide with a conviction, the absence of her remains means that for Tammy's family, a final sense of closure remains elusive.
