I think the Crown has to be very careful when determining the validity of 50 potential witnesses and because there were so many it is taking longer to corroborate statements. Some key witnesses may be scared to talk or in hiding. It doesn't surprise me based on the event in itself that they would have a lot more work to process beforehand.
As for this case I wonder if the blog and arguments etc. could have been enough for first degree or if GR admitted to doing it. If the investigation was ongoing at the time of the charges is it possible the charges could be lessened at a later date in the same way that further charges can be laid?
If her autopsy came back that she had a significant alcohol and drug level content would that be taken into consideration in the defense of the accused or suggest or validate a defense that both were provoking one another? If so would it still fall under first-degree?
If the tables were turned and BW killed GR in the heat of an argument and police had the blog entries to suggest a crime of passion would she have been charged with first-degree? Or would there have to be more? Is the broken window alone showing pre-intent? I am curious how that works.
Here is the law - I took out a couple sections where this case wouldn't be relevant:
Classification of murder
231.*(1)*Murder is first degree murder or second degree murder.
Planned and deliberate murder
(2)*Murder is first degree murder when it is planned and deliberate.
Contracted murder
(3)*Without limiting the generality of subsection (2), murder is planned and deliberate when it is committed pursuant to an arrangement under which money or anything of value passes or is intended to pass from one person to another, or is promised by one person to another, as consideration for that others causing or assisting in causing the death of anyone or counselling another person to do any act causing or assisting in causing that death.
Hijacking, sexual assault or kidnapping
(5)*Irrespective of whether a murder is planned and deliberate on the part of any person, murder is first degree murder in respect of a person when the death is caused by that person while committing or attempting to commit an offence under one of the following sections:

(7)*All murder that is not first degree murder is second degree murder.

As you can see, the first degree charges may be as a result of a few possibilities.
