|“||I left my husband for him. I left Thor for him. And he was going to leave me? What was I supposed to do?||„|
|~ Anne Marie Ostenbach|
Anne Marie Ostenbach is the main antagonist from "Death in the Saddle", episode 3.03 of Bones.
She was portred by Christina Cox, who also played Zoey Kruger in Dexter, and Krysta Pullman on Elementary.
Anne Marie Ostenbach is a regular participant at the Ambassadora Lodge, a place where wealthy people engage in a sexual roleplaying fantasy that involves "horses" and "riders". In the case of Anne Marie, she was a rider going by the name, Annie Oakley, with a man named Ed Milner, who was later murdered, as her "horse". She is encountered by Bones and Booth at the Lodge regarding the death of Milner, who was referred to as "Mr. Ed," and she stated that Milner's wife, Alice, caught them in their role play.
Anne Marie was later revealed as Milner's killer while Bones and Booth interrogated her at the lodge once again. She had developed a romantic affinity for Milner, and stated that she had left her husband and Thor, a lover at the lodge, to be with him. However, Milner refused to leave his wife, and with that, Anne Marie talked Milner into having one last roleplaying session, only this time, she went into a rage and killed him. She used a hoof knife to cut off Milner's feet, and after tying his wrists together, the enraged villainess gouged his eyes out. Anne Marie was later arrested for murdering Milner.
