Same here. Just found this at Gamespot.
"He appears in multiple places: Twilight Cathedral, Anvil's Ford, Choking Grounds, and a few others. He's like a repeatable mini-boss, worth 2,000 souls. You have a few options for beating him: Chaos Form, Affliction, and Tackle Harpoon between his attacks."
Explains why he keeps vanishing rather than dying!
