Tommy D'Antonio was a small-time criminal from Allendale who travelled south to Florida in hopes of better prospects. Instead, he got mixed up with a creep named Matheson, who had him stealing from drug dealers. Michael met up with Tommy to try and get to Matheson, hoping to hand the criminal mastermind over to Det. Paxson in order to get her off his back. However, when he learned that Tommy wanted to leave the criminal world, he and Sam and Fiona helped Tommy set up Matheson in a trap.
