You locate 5 of the 6 bodies and one of the five has already been searched by Rowan. The missing body was one on the roof. Each dwarf averaged 50gp and one potion and carried shortsword and crossbow.
Total 200gp, 4 potions, 4 short swords, and 4 crossbows.
This is in addition to what Rowan found on the dwarf he searched earlier.
