OK so lets assume the diagram, as posted by Kaldin, is a true and accurate representation of where the cases lay on the morning of the shootings (bar the case on the stairs).
Having viewed the pictures of where Sheila lay and the pattern of bleeding from both the wounds in her neck it appears to me the two shots occurred within a short time of each other (a couple / few seconds). This is because there is a common pattern in the flow of blood which would be influenced by gravity.
Is if a fair interpretation that both wounds occurred within a short period of time?
..............................
I beg to differ about blood running and leaking from both wounds - I think there was blood leaking from only one of the wounds, and that as a result of Sheila's body, and head being repositioned, the upper wound came to rest upon the lower wound, and blood which is shown, or which appears to be running from the lower entry wound, is in fact blood that was running and leaking from the upper wound, before the position of the victims head was adjusted into a different position...
If you look close enough, you can see that there is no vblood running from the lower wound at all, only the upper wound...
Blood from the lower wound, ran in a completely different direction - which you can see if you care to take the time and trouble to notice...
In my opinion...
Mike, if you could post the picture / pictures which best represents this, in your opinion, I will gladly take a look and post my comments.

Please take care to look at the possibility that the victims head was bent forward, and that the upper entry wound rested over the lower entry wound, at a time when there was no blood running or leaking from the lower wound? With the head in that position, blood from the upper wound began to run across the neck, and then once the position of the victim's head was repositioned, blood ran from the upper wound, in the same general direction it had been running, as though it had ran from the lower wound...
Evidence that the head had been tilted forward can be found, by reference to the bloodied finger marks around the upper entry wound, being duplicated ion the surface of the skin around the lower entry wound...
Once the head had been repositioned and blood began to run and flow naturally from the upper wound, it proceeded to run over the top of the bloodied finger-marks adjacent to the upper entry wound, , but not from the lower entry wound, because by that stage, there was no blood at all running from that wound...
If you look closely enough...
You can see that blood from the lower wound, actually ran and flowed in a totally different direction, than blood from the upper wound...
in my opinion...
