When does an enjoyment of varied interests become a double life? That is a question pertinent to the tragic and strange tale of Roseann Quinn. Many will be familiar with this name, even though her death dates back three and a half decades. That is because the case of Roseann Quinn is the one behind the well known 1977 film, 'Looking for Mr Goodbar', which starred Diane Keaton. It is also the inspiration for Judith Rossner's slightly less well known but still best selling novel of the same name, and the account by the New York Times journalist, Lacey Fosburgh (called 'Closing Time: The True Story of the Goodbar Murder.') Sometimes, it can be tricky to understand why some crimes make their way to the eye of popular culture and other, equally tragic, events fail to do so. Although, of course, every death is a tragedy for someone. But in the case of Roseann, the answer is clear to see.
