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 crime scene of a double murder shows evidence of conflicting motives. But an unlikely clue on the living room floor helps Detective Postiglione zero in on what really happened, leading to the arrest of an unassuming 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.

Detective Postiglione investigates a crime scene where pools of blood indicate that something terrible occurred, but the female victim is nowhere to be found. It's up to Postiglione to find her and a possible murderer.

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 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.

While investigating two separate homicide cases, Detective Pat Postiglione discovers that the same psychotic killer is behind all the murders and has a unique calling card.

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.
