What are three theories to solving the Black Dahlia murder case?

At this point there are not three theories that could solve this very cold case. There is only one. Thanks to the science/art of criminal profiling it is clear that Elizabeth Short was not the killer's first victim. In fact there were two previous murders in the Los Angeles area that remain unsolved and can be circumstantially linked to the Black Dahlia. Known as the 'bathtub' murders, they have many similarities to the later case.

Due to the notoriety of the Black Dahlia case, there is very little left of the physical evidence in police archives. Pilphering evidence from famous cases is not unheard of. But the two murders before Short's barely made a ripple in the L.A. area. There is most likely evidence in those files, that may be able to not only tie the murders together but may shed some light in the Dahlia case.

This seems to be the best chance of solving the Dahlia case. Why someone has not done this is a mystery.

Motive, escape, and identity are the remaining elements to be proven. Though not 'theories', there is no consensus on any of the above referenced aspects of the crime.
