Born on October 14, 1968, Falsone was introduced as a long-time member of the Auto Squad at the end of Season 5, where his natural talents proved useful in solving vehicle-related crimes.

However, when the department began a rotation program, in which detectives would be periodically reassigned to new units, Falsone was transferred to the homicide shift commanded by Al Giardello.

Meldrick Lewis, are shot at by Junior Bunk on behalf of the crime organization run by Georgia Rae Mahoney.

Falsone's investigation leads to a suspicion that the shooting of Georgia Rae's brother Luther (the original head of the organization) was not legitimate, a suspicion which ignites a long-standing enmity between Falsone and Mike Kellerman, the detective who shot Luther during the previous season.

During Season 7, Falsone begins dating fellow homicide detective Laura Ballard, who joined the unit at roughly the same time that he rotated into it.
