Kate Tenny is the agent and killer of actor Dale Marks. Kate suffered teenage prostitution and decided to write a derivative memoir on the lives of several street children under the alias “Sweetie Ness”, then hired Marks to pose as the author.
When she needed another book, Kate killed Marks to get rid of him as a liability. She successfully framed Cody Larson, the book’s primary inspiration, for the murder, but the conviction was vacated.
It’s unknown if she was ever tried for the murder. (L&O: “Sweetie”)
