Not saying she (or even Nick's mom or grandpa, given the ages of the combatants) didn't but that is something for the writers to contrive for more forced drama In Bears Will Be Bears (at least according to this Wiki, on Monroe's page; I can't check because I lent my Season 1 DVDs to a friend), when Monroe is guarding Aunt Marie in the hospital:

"In particular he has heard many frightening things about Marie Kessler, Nick's aunt, who seems to have a bloody reputation in the supernatural creature world. His great-grandma's head was cut off and placed on a lamppost by Marie. His grandfather was mutilated by the Grimms and his farm was burned down. He does admit that his grandfather may have deserved the treatment for some of the things he had done."

But sometimes they say things and then kind of retcon them, so we'll see.
