The crier for the Silver Rush is a middle aged man who is one of only a handful of people who has a job in Freeside and one of a few criers in this area. He is employed by the Van Graffs who pay him to boost the public's awareness of their establishment and help bring in customers. He's standing just below the Freeside sign in the second section of Freeside (the section which has the New Vegas Strip entrance).
During Kings' Gambit he might kill Pacer after you plant the letter.
If you have completed Heartache by the Number by giving the evidence to Ranger Jackson at Mojave Outpost, He may become hostile.
Bugs[]
While doing Heartache by the Number, the Silver Rush crier may attack the player along with several Freeside thugs. This in turn causes Simon to attack as well.
