Who is Griffin Scopes, and what is his importance?

In Chapter Seven, the reader is introduced to Griffin Scope, a wealthy billionaire, who was born rich. Scope's father, however, believed in hard work and required Griffin to work hard and attend public school rather than private. On a particular night just after David receives the email, David's sister Linda is overseeing a party thrown by Griffin Scope to honor the memory of his son, Brandon. Brandon had been murdered, and the party is in the name of the Brandon Scope Charitable Foundation.
