Older Man is an unnamed man.
He had originally been a congressman. However, after he had been caught ordering for the services of a prostitute and presumably arrested alongside her (with it being broadcast on news outlets such as TNZ), he was sentenced to a month of community service, including picking up garbage off the side of the road. During one of the days he was due for community service (where he was annoyed by another man, Gary, referring to him as a Senator instead of a Congressman), he and Gary ended up stumbling upon a motorcycle on the side. He then called over his boss to inform him of what they discovered, and eventually found David Austin's corpse a few meters away.
