I just had a thought, the ransom note had Victory! at the end; could it possible be connected to a "V" on her hand? As a staging?
The coroner and Patsy referred to the drawing on her hand as a heart, not a V, though it looks like different things to different people. Some see a heart, some see a V, some see a smily face.
I had read long ago that Patsy used to draw a heart on her hand and say "My heart is in your hands".
