You'll find the entrance to Oscar's hiding place to the north of where the yellow X is on your map. Go behind the building and down the stairs. Go into the tunnel and around the bend. Kill the Straccis hiding in nooks on both the left and right. Go past the nook a little, then wait. More Straccis will drop a couple of burning barrels down and they will explode.

You can try killing these enemies, but you may be better off just ignoring them, and running quickly past the area where they will be able to shoot at you. As soon as you turn right into the next tunnel, be on guard. There will be more Straccis ahead. One on the right, one on the left, plus Oscar himself. Take out the two guards, then shoot Oscar in the knee, then the shoulder, then the head.
