There is one aspect of this whole sorry mess that puzzles me. Why choose heroin as a means of killing (or murdering) her son and how did she know where to get it?
It wasn’t the first time she’d tried to murder him by giving him an OD of heroin either.
I reckon that most people wouldn’t know where to buy the stuff (illegally) and wouldn’t use it as the murder weapon of choice in any event.
As I understand it, the mother was a nurse and would have had some medical knowledge. If she wanted to murder her son in a painless way, surely the ‘plastic bag over the head’ method would have been far simpler and equally ‘painless’.
I find myself wondering if there isn’t more to all this than initially meets the eye?
