Brad was a guard in Butcher Bay Correctional Facility.
Brad and Lowe had trapped another guard in an elevator by stacking boxes under the elevator and between the doors. The trapped person asked to be released, Lowe wanted an apology for something, which he got. After asking again to be released, Brad only answered "Maybe". When disguised Riddick asked them about it, he said that as far as Riddick is concerned, this never happened.
