Brian (surname unknown) is the manager of Lisa Downey and Angela Agnelli's favorite clothing store, Her Boutique, at the mall. The girls would constantly get the best clothes in exchange for sex with Brian, who they seduced for the favors.
When Lisa was found murdered, her extensive sexual life ended up at the clothing store, and Brian was found in a stockroom receiving oral sex from Angela when footage previously showed him going into a dressing room with Lisa. Brian was likely charged with statutory rape. (SVU: "Hooked")
