Karen Tilly is a woman whose husband Jasper vanishes in "The Census of the Lambs".
When Stan comes up missing as well, Hayley discovers that other men in the area have gone missing as well. When she interviews Karen, she finds that Karen is puzzled as well, but is distracted enough that she fails to notice until it is too late that in her pruning, that she has cut the head off of a squirrel. She points Hayley in the direction of Darlene McKinnon who also has a missing husband.
Karen is voiced by Mo Collins.
