Bud Wurstner

Bud was a repair man employed by the firm responsible of servicing detective Burkhardt's refrigerator.

When he met Burkhardt for the first time in, it was revealed that he was, in fact, a creature of some sort who immediately recognized Burkhardt as being a Grimm. He reacted with extreme fear and fled.

In, he told two others, probably of his species, that he had been in Nick Burkhardt's house but they were skeptical. The three went to Nick's house after dark and saw him arrive home. They then sped away in a car.
