Marcus White is one of Dexter Morgan's many victims. During the Bay Harbor Butcher Investigation, FBI Agent Frank Lundy runs through victims without a criminal record and points out Marcus... claiming him to be a tow-truck driver with absolutely no criminal record. Debra later reveals to Lundy that Marcus's sister spilled information that he killed their parents and made it look like a car accident because the living trust was in his name. However, it is never revealed how Dexter discovered his crime.
