Owen Franks is a chop shop operator associated with Lamont Tyler, who killed Anna Hopkins to steal her SUV and sell it to Franks. Since biohazardous waste was in the trunk, Franks went nowhere near the car and kept it in his back lot.
Detectives entered the premises after claiming they heard a woman screaming, and they found Hopkins's car with the waste. While they called for backup and a hazmat team, Franks requested a deal in exchange for giving up Tyler, but they arrested him, saying they could bargain with the prosecution. Franks' ultimate legal fate is left unknown. (L&O: "Patient Zero")
