Yes and they have this other charges made against him alone( voyeurism & sexual assault) and the indecent images of a child for the pair.
Naturally I have only just found out about those, from this thread.
(Prior to this thread I didn't have any real thoughts as to motive, I didn't read all the news articles on it - a domestic violence angle is all I thought complicated by sibling rivalry perhaps. )
After reading the thread and starting to back track on the articles ( b
efore I heard about the extra charges) I thought the police know best and they are seeing this as sexually motivated. When they say that it doesn't necessarily mean the perp wants to have sex with the victim though. (There can simply be a sexual side to the violence/attack.)
On reading more it seemed clear to me he has some fixed sexual compulsions and his "pretty, petite teen" fetish and addiction to *advertiser censored* ( esp as it fitted the object of his fantasies) and a step-sister he has known that long, who was also fitting that bill ( esp when she was very slim through anorexia) may have been the object of long held dark fantasy for him which he can't admit too. For me, combine this with a savage treatment of the body -against a family member even when not close- I thought this man is capable of something quite twisted plus must have psychopathic tendencies. ( To now hear the path say how meticulously that was carried out, it confirms both his detachment and possibly some level of satisfaction in that task.)
Anyway, I am still open to other ideas, and I do think it could be
possibly something simpler- a row that got out of hand etc, I think the cheque thing is really interesting, but then I come back to the purchase of two stun guns in advance in Dec/Jan. This man was not AFAIK just a collector of weapons etc like some young men are. (For me it fits more with his desire to incapacitate someone and planning and his fantasy dark side.)
The fact that SH and NM's reln. was no holds barred re. other women ( even if just compliant ) and the *advertiser censored* was a in-joke twixt them makes me think he could even have discussed his sexual feelings towards BW with SH.
However I think they both knew that BW would never have a 3some with them even if they asked her so I don't necessarily believe this is as simple as a sexual offer to Becky that went wrong. ( Anyway that's my cod psychology contribution!
)
TBH I don't know what the motive is and it's good to explore all the simpler options too.
Whatever it is NM says, think the opposite, so yes could be a cheque or £ issues that spark, could be just as Cherwell said a row that gets out of hand but bizarrely he cannot admit to that and has to say "I did it for my mum" almost! Def need AG on the stand, she is crucial. That would rattle him on a deep level. They have exchanged a smile even recently, during trial haven't they.)
PS I would have expected more of a history of violence from this guy to come out ( beyond SH's accounts)
