What is the nature of the dangerous driving?
What caused her to lose control?
the trouble with this is that what you are describing is causing death by dangerous driving rather than just dangerous driving.
For causing death by dangerous driving people go to prison for much longer than two years even when they are female and even when they trot out the usual excuses of domestic violence and sexual abuse.
The fact that she had placed the wife in a coma would have been dealt with at the time of the original matter.
Even if the wife subsequently died CPS would revisit the matter because she was prosecuted for causing death by dangerous driving at the time.
And the fact f killing two people rather than just one doesn't really make all that much difference to sentence.
Can I clarify anything for you?
I can't find another question against your account.
In any event, I will give you the sentencing guidelines
Page 4 and 5 are relevant.
Also, page 8 and pages 12-13 where you will find the ranges.
Although you do need to decide what caused the loss of control as that may knock it into the lowest bracket.
That said, it is fair to say that women do get far lower sentences than men.
Sorry but since you have asked for a refund I will not be able to help.
