I've followed just about every page of this thread and know that many have provided valuable info about and photos relating to the Black Dahlia mystery, however I did want to post a link to a 3 part video on Elizabeth Short that is part of James Ellroy's Feast of Death on BBC Four (2001). Hopefully it's not a repost and excuse me for my ignorance if it is..., I for one found Larry Harnisch's (former LA Times writer) theory very convincing. Here it is for all of your enjoyment.
