I will be very interested to read the Court Sentencing Report on him. The judge will make some very clear comments. It will not be released for a while after the sentencing which is this Friday.
He will get a life sentence, that is the rule. As to the tariff, the only mitigating factor I can see is no premeditation. There are plenty of aggravating factors.
This man is an evil, angry brute. If it had not been the particular victim that night it would have been another, probably his partner. If it had not been that night it would have later in the holiday. Or if not on that holiday, a month later on someone else when back at home. Clearly he was simmering.
I am glad he will go to prison for a very long time. The starting point for murder is 15 years. Add to that another 7 years for the fact the victim was a 71 year old vulnerable lady. Probably add another 5 years for the way in which he killed her. That takes us to about 25-27 years. The only mitigating factor may be given little weight. He assaulted her in a manner that he must have known he intended to kill her, particularly throughout the assault. Any reasonable concerns as to the safety of himself and his property were far exceeded and he would have known that.
I am betting he gets 24 years. I wager this will be the minimum term he will serve of his life sentence. At the end of that term he will be 70. He will be released only after The Parole Board consider he is no longer a danger to the public. There is always the potential he may never be released.
