Tricky this, you know not being there and all that.
Having listened to all the “evidence” and soundbites that Sky/BBC report I have formed an “informed” opinion. That opinion is this:
Having had a blazing row with her over something quite incidental, he wouldn’t let it lie and it erupted into a stinking bost up. His temper go the better of him, she ran for cover into the Loo and he was so enraged that he offloaded a few rounds of bullets, designed to frighten the shit out of her, however she was unfortunately in the way of those bullets.
I get the impression that his modus was to frighten, however knowing bullets can kill he had the motive to at least hurt/threaten and therein lies the rub.
Motive, outcome, manslaughter IMO.
Remorse, yup I think he has buckets of it, can’t think what he’ll get if found guilty but spending a large proportion of his time in prison isn’t what he had in mind, nor trained for. It’ll kill him.
