I wont say that these are self inflicted but i am sure these were not meant to harm her to a great extent either. The cut on the neck could have killed her if done properly and the one who did that had all the time in the world to do it properly yet he did not. The elevation of cut from left to right is also unnatural for a right handed person (if she is).
Plus the cuts are mostly superficial as far as i can see. Stab on the forearm, (ARM!!) cut on RING FINGER (was she mentally stable and happy?) Bruising on her hand (If this from cutting that glass scree or help set up that break in). While she lost some blood due to these cuts, none of these were extensively lethal.
Although there are no evidence suggest Rebecca is left handed (not beyond reasonable doubt) the cut on her left finger would probably suggest implication (ie cutting her own hand with the weapon) Otherwise, all other wound are superficial and cannot be suggest whether or not they are self-inflicted.
The bruise cover a large area under both her arms and in her wrist, so it probably not suggesting the bruise were from the break in.
But one thing is certain from the wound pattern between Rebecca and her two sons, the pattern of injury does not match, either there are 2 persons who did the slicing and dicing, or they are intentionally made different. That bit is quite conclusive.
This is serious and in light of other findings only support the point of view regarding an accomplice. She herself would not have taken that kind of risk and i am not sure if she wont know that there is this important main blood vessel at this spot. Since it was not the life of accomplice at risk, he was just a bit careless about it.
The wound to the neck is circumstantial, because the prosecution could argue she or anyone did not know such blood vessel exist without proper medical training.
Would flag this. Further strengthens that argument that the sock was placed there by someone else, someone other than Rebecca as she was injured at that time and would have left a blood trail. The KILLER would have left some spots as well, or stained boot prints but nothing there either. So i feel there was someone else involved as well. Killer seem to be Rebecca.
This is actually the most puzzling evidence for the whole case, the probability of that sock exist does not make sense. However, the sock, itself, is not exactly a physical evidence, it is a circumstantial evidence, because it cannot either proof or disproof anyone involvement in this murder, in fact, the sock itself cannot be proof or disproof beyond reasonable doubt that it came from the crime scene.
Plus please note that even though there are evidence of someone else present there, it is not like the classic break in. There are doubts about the screen that was cut (if it was from the inside or outside). No dust have been disturbed at those points. There is no print on screen either. A kitchen knife from the family's set is found IN KITCHEN with traces if the material that was cut. The intruder from outside would not have access to that knife to cut that screen.
Since you mentioned that the case is from 90s, i hope Rebecca is either in jail or have been sent to death and the accomplice have been found and charged as well. Personally, i am sure that there was someone else involved, someone else present there. Do anyone here disagree with this? please share what you think i have missed?
The case, was quite circumstantial for both the mother and the father, as there are gap exist that does not quite fit the overall picture, I guess the majority of the issue regarding Rebecca as a killer is that it only make sense either it was done by a third party, or Rebecca is working with a third party, however, the physical evidence of a third party involvement is lacking, there are quite a few circumstantial evidence of a third party did exist, but short of actual proof linking to the case (There are no DNA nor Other Physical Evidence exist for a third party, beside Rebecca and Ron and the 3 children there inside the home of Rebecca and Ron. And that is the problem for the "third party theory" that either support or against Rebecca Guilt.
The prosecution would need to either,
Established that third party did exist and is working with either Ron or Rebecca or both to commit the crime or
Established that third party DID not exist and either Ron or Rebecca or both commit the crime themselves or working together.
What about neighbour RN.... I have my doubts on him ... may be he was having an affair with rebecca
The RN is a woman....And she was with her husband the time of the murder and was at home immediately afterward.
One thing is sure that the motive behind the incident is murder of kids only not burglary ( if kids got stab multiple times then crystal clear) . Otherwise why not the intruder killed rebecca too. Surely rebecca is the killer other wise who talk to emergency service for 5 mins when both of her kids are dying. And her husband is just trying to cover her may be for insurance claim.
The motive as to why the case happen the way it happened is hard to determine.
The circumstance is that, this case does not look like a normal break-in or B&E (Breaking and Entering) because the first thing the person or person(s) do is to kill the occupant inside, also the alleged place the person or persons break in is not directly connected to the living room where the 2 child was killed. That would mean it was premeditated (ie a through of malice as the person or persons intended to kill)
However, there are no evidence suggesting the husband of direct involvement on this crime.
hmmmmmmm ..................
The father went out of the house to approach KN for help, before performing CPR on 2? 2 had already expired why didn't he concentrate on 3?
9 minutes ............... Rebecca took 5 minutes or so on the phone, police took over 2 minutes to reach the crime scene (lets say 2 minutes) that makes it 7 minutes ............ so the boy was stabbed 2 minutes before Rebecca dialed 911. And in those 2 minutes she chased the killer, came back made the call, the police officer who responded on phone can he / she remember if Rebecca was heavily breathing?
The postmortem reports of the boys .......... are there any signs of torture and boys being drugged in past or near past? The sock filled with blood could have been arranged well before the actual crime by simply taking out some blood via injection syringe.
I would like to grill KN as well she is the nurse and holds medical knowledge, someone who could assist inflicting wounds on Rebecca, she can be a potential accomplice, plus details of Rebecca's and her husband's acquaintances anyone with a black car.
The dad claim was to give CPR to resuscitate the boy that he think is not breathing, which mean he would have gone to help the child that is already dead (or at least not breathing.)
Rebecca status during the call is of panicking and shocked, the first responder arrived at about 4 minute mark during the 9-11 call, but was not doing anything until backup arrive, back up arrived to the scene the same time the Paramedic Arrive, after back up clear the house, Paramedic go in and treat the boys.
KN was grilled and was cleared by the police as a potential suspect.
