Retired NFL superstar Steve McNair is found shot to death along with his young mistress. Pat Postiglione reveals the true story of his investigation and its shocking conclusion, which has become the most talked about murder mystery in Nashville history.

The deceased body of a young mother is found naked and gruesomely displayed inside a public truck stop near downtown Nashville. Det. Postiglione uncovers a trail of evidence across multiple states that leads him to a serial killer.

In 2004, Detective Postiglione investigates the rare double homicide of two young college students in an apartment near a Nashville university. When a third victim is gunned down, Postiglione launches a state-wide manhunt to catch a ruthless killer.

In 1987, Pat Postiglione is tasked with solving his first homicide: a young mother strangled to death inside her apartment while her children are in the other room. Without any viable suspects, Pat faces the daunting task of interviewing his only witness: the victim's 4-year-old daughter.

In 1993, a night clerk is shot dead inside the lobby of a hotel. Despite eyewitness accounts, Det. Postiglione can't locate the killer. Recalling subtle clues left outside the crime scene, he finally comes face-to-face with a most unusual suspect.

In 1991, a woman is found murdered inside a Nashville motel room. The investigation escalates after Detective Postiglione discovers a similar crime scene in Cincinnati, sending him on a year-long odyssey to capture a serial killer.
