This case highlights what some men in immense positions of power will do to try and cover their tracks. Anne Marie Fahey was only 27 when she was murdered by Thomas Capano, a prominent lawyer and political consultant who was well-known in Delaware, and who came from a family of rich real-estate developers. Although their relationship was not exclusive by any means, Capano was angered when he thought Fahey was going to end things with him, wanting to keep Fahey all to himself.
