Background
He and two members of his gang are encountered in Highland Park, right after the arrival. Adam Jensen can ask him about the area, and buy a couple of items. He'll say that the area is currently occupied by unknown Spec Ops soldiers, later revealed to be part of Belltower Associates.

His wares include Target-Leading System upgrade for the crossbow and tranquilizer rifle, some ammunition and a grenade pack consisting of one gas and EMP grenades.
