I haven't seen anything about what was actually said on Mark Kelley's show so here ya go if anyone is interested.
Mark Kelley spoke with Vincent Clifford who has represented eighteen high profile defendants in the Ottawa area, including being apart of the team that represented Russell Williams. Here's how he sees things:
Derstine is dealing with two different versions of what happened:
1. TLM's version in May 2009: MTR beat and killed Tori
2. Current version: while MTR raped Tori, she is the one who killed Tori
Derstine's strategy is quite simple, he wants the jury to believe TLM's current version. And that while he may be guilty of an underlying charge, he did not murder Tori.
The first option is devastating to the client, while the second allows verdicts other than first degree murder to be considered. The jury might be able to consider manslaughter, or the underlying offenses of sexual assault and kidnapping, and they could even deliberate on an outright acquittal on the homicide charge.
Kelley asks if an acquittal is really possible, and Clifford says that anything is possible (don't we all know that )
There is potential that this strategy could backfire. But what Derstine's has to do is refer to TLM's journals, her letters, her conduct, poems, songs that she liked to convince them that she is capable of committing this homicide on her own, without MTR.
MK asks what the defence now wants from MTR. Clifford answers that probably only two people know the answer to that, MTR and Derstine. But based on his experiences he thinks it is important to remember that the Crown attorney bears the border of proof, of proving beyond a reasonable doubt that MTR killed Tori or was a party to her killing. The Crown does not have to show who swung the hammer, but if they want to convict MTR of the murder as a party they do have to provide evidence beyond a reasonable doubt that he had a guilty mind, that he intended to kill her.
This is not verbatim, but close to it.
