Henrik Van Der Voot

From Adrian's Persons of Interest:
The Coffin-Maker Henrik Van Der Voot. He was convinced to pay Milivoj to steal the bones of Saint Andral. The innocent (and slightly clueless) Gravedigger got the bones for him which he hid in his house, tucked under a cabinet in his bedroom. He was sheltering six Vampire Spawns that went on to attack the citizens of Vallaki during the Festival of the Burning Sun.
We informed the Burgomaster of Vallaki of his misdeeds, he tried to lie his way out of it. His weak spine is probably what allowed Strahd to bully him into aiding The Devil. He probably met his death when he was strapped to the giant wicker Burning Sun during the Festival, or was eventually consumed by the surviving vampires that he sheltered. Although...
Maybe they helped him escape? Who knows.
 It would be worth interrogating him if he is still alive. 
Good to know how Strahd gets 'normal' people to aid him.
