Interpol has a program specifically seeking to identify the unsolved deaths of women.
After identifying one British woman a few years ago, bringing closure to her family, it seems that a second woman may have been conclusively identified this week. There are still many more to go.
You can read more about the program and the cases here, but be aware of the difficult reading.
