Warning - Novel alert!
After a few days of the dreaded man flu which allowed me a bit of time to reflect on this case and an impromptu visit to the Kholo Creek Bridge, I'd like to weigh in with some observations if I may
During the case I purposely ignored any evidence ruled inadmissible, some of it I had obviously heard and had to discount for the purposes of this exercise and other parts I had neither heard or read. The autopsy report was one such document that I had not read until recently.
During the trial the pathologist who examined Allison, Dr Milne, said that he would expect fairly significant injuries (bone fractures were mentioned) if a person was to fall 14 metres. Common sense would deem that to be the case, there have been isolated reports of falls from a similar or greater height where minor or indeed no injuries were sustained, but they were isolated.
I had no qualms with this until my recent trip to the western suburbs where, on a whim, I visited the site. Let me go on record as saying that there is absolutely no chance that the position of Allison's body was 14 metres or more below the bridge. I note the wording in the autopsy report where Dr Milne states "approximately 14 metres above the water" (this is ambiguous in any case, the water level could have differed by anywhere up to about 2 metres depending on the state of the tide). Given that the prosecution argument was that she was 'lapped' by the water at best, I think the defence dropped the ball by not pointing out that she must have fallen less than 14 metres by the prosecution's own admissions. Anyway, moving on.
Even if the measurement was taken to the mean low tide mark (which was well below where Allison came to rest), I don't believe it to be accurate. Humans are prone to overestimating their height above the ground, for some kind of reference, 14 metres is the equivalent of a 4-5 story building. I find it difficult to imagine that the distance to Allison wasn't measured exactly but given the obvious discrepancy and the vague reference 'to the water' it appears to me that it wasn't. It was possibly eyeballed or perhaps an investigator relied on a reading from an altimeter which showed a reading of 14m above sea level (which would be somewhere in the ballpark I imagine) and erroneously thought sea level equated to the water level in Kholo Creek.
I had no measuring equipment on me but if I have the location of Allison right, and I'm quite sure that I do, I estimate the drop to be ~8m with perhaps a margin of 1m either side. Obviously I'm only eyeballing this myself but after many years as a rock climber, I'd like to think that I have a pretty good grasp of distances as quite literally your life depends on it sometimes!
8 metres, or somewhere around that mark, is obviously still significant but at almost half of 14m, the potential for a fall with no fractured bones is considerably greater than what it would be from 14m. You can die from a 2m fall but likewise you can avoid injury from a fall from a surprising height either through good fortune or good management (parachute landing techniques etc.).
I obviously think that this should have been examined more in depth at trial, ultimately it may not have made any difference (as Allison was found partly under the bridge it unlikely, if not impossible that she could have fallen directly to that location anyway) but it is something that should have been explored anyway IMO. Which brings me to my next point.
If, as the Crown suggested (and seemingly was not countered by the defence) Allison could not have fallen directly to that location from the bridge overhead, why was the figure of 14 metres even mentioned in terms of potential injury that could be sustained? It seems to have been a needless tangent which may well have had a negative flow on effect throughout the trial.
I understand that the embankment under the bridge is not as steep as it was in 2012 and after examining photos from that time, it's obvious that there was indeed quite a steep gradient, indeed it had to have been for Allison to come to rest from where the prosecution said she was pushed from. If we assume that she could not have jumped/fallen/been pushed from the bridge directly to her location, why was the possibility ignored that she came off the bridge (by whatever means) at a location above the gradient at which point she then rolled to her final location or is it possible that she could have slipped somewhere in the vicinity of where the Crown established that she was pushed? Obviously it was accepted that GBC pushed her from a ledge adjacent to the bridge so it has to be equally plausible, if not more so that she could have wound up in that location as a result of attempting to arrest her fall or attempting to extricate herself before losing consciousness (Dr Milne also indicated this in his report). FWIW it’s not my personal belief that either scenario occurred, but I couldn’t exclude it and I'm puzzled as to why the defence did not question Dr Milne at length over this possibility and of course I don't know why they accepted the 14m measurement (assuming it is wrong, and I'm virtually certain that this is the case).
Another height reference - Many people who visited the site will have also walked over the Goodwill Bridge. The height of the GB is 13.25m above the highest yearly tide making it roughly 14m above an average high tide which makes it an almost perfect example. Anyone who has seen the 2 couldn't possibly argue that the heights are similar, the Goodwill is noticeably higher. I will endeavour to get out there with a rope and measure, or anyone local please feel free to do it on my behalf
Moving on to parts of the autopsy report that were excluded from trial (on defence application). Obviously of specific concern are both the possible subdural hemorrhage to Allison's brain and the bruising to her left ribs. Dr Milne was of the opinion that one or either injury could have been the result of either a fall or an assault (presumably it's possible for both to have occurred) but was not permitted to advance this opinion at trial.
I can understand the defence application in light of their suicide theory but even then I would have been tempted to allow the evidence as Dr Milne agreed that the injuries could have been the result of a fall, and the possible subdural hemorrhage was indeed a potentially fatal injury. Obviously the question still remained as to how Allison got there of her own volition but that's neither here or there now.
In my opinion, a far more plausible theory than suicide (which in light of the autopsy report still seems somewhat possible, albeit unlikely) which remained favourable to the defence was that Allison was the victim of a terrible accident after an altercation with GBC although obviously this scenario would have necessitated either GBC not giving evidence or giving a different version of events than he did.
People have speculated on his seemingly odd behaviour during and after the time he reported Allison missing. Although I have never been in a position where a loved one has gone missing, and I hope I never am, he did seem rather unconcerned given the circumstances. I can only conclude that either he just didn't care, or he knew what had happened to Allison.
One of the reasons I bring up GBC's behaviour is his reaction to the guilty verdict. Typically people who are found guilty either show little emotion or occasionally fly into a full on rage but GBC's behavour, as described to me as I wasn't present, seemed at odds with a typical reaction given the circumstances. I raised this subject with a respected criminologist who has a significant degree of knowledge of this particular case and they agreed that it was not a typical reaction. Obviously neither of us are psychologists but it crossed my mind that although he could have been responsible for Allison's death (and ultimately a jury decided that he was and that it was murder), it did not occur in the way portrayed at trial which could also explain his confidence that he would ultimately be acquitted.
I put the following to the WS jury....
On the night Allison went missing, she and GBC had a disagreement about something (whether it be about TM, finances or whatever). Not wanting to alarm the kids they went outside to talk and for whatever reason it turned physical at which point one of 3 things happened.
1. Allison and GBC were both engaged in an assault, Allison scratching and bruising GBC's face and torso and GBC attempting to fend off or punch Allison (bruise to the ribs) and then punching her to the left side of her head at which point she became unconscious and fell to the ground.
2. As above but Allison's fall may have been accidental and not the result of a blow to the head, the hemorrhage occurring upon contact with the ground.
3. And this is going to be distasteful to many, could it be possible that GBC was not trying to engage in any assault (limited superficial injuries to ABC) and instead was trying to extricate himself from the situation, pushed Allison away who then fell?
All of the above could explain the leaves in Allison's hair, the injuries that Dr Milne noted (particularly if GBC is right handed, I'm unsure of his dexterity though), the blood in the Captiva and the injuries to GBC. It would also go some way to explaining his demeanor immediately after the event and his bewilderment of being found guilty when the prosecution case was significantly off the mark.
Obviously you'd have to ask why wasn't medical attention sought and the subsequent subterfuge but GBC certainly wouldn't be the first person to panic and act irrationally when an accidental death has occurred.
I have to add this disclaimer, I'm in absolutely no way suggesting any of the following occurred and the Crown and jury may have got it right down to every last detail. But with the benefit of being privy to evidence that was not admissible, I would have taken a completely different tack from the one taken by the defence but which would have necessitated either recanting previous statements or GBC not giving evidence at all. Disregarding potentially incriminating behaviour after the fact, I can see no reason to suggest that the above scenarios are any less plausible than the asphyxiation theory which was ultimately accepted by the jury. It may well be the case that it was manslaughter (in that it was 'just' an assault with no intention to kill or inflict GBH) or even just a tragic accident after which GBC panicked.
I have to say that as prosecutor, I would have been a bit uncomfortable leading a case where evidence that had been excluded (again, at the request of the defence) may potentially have contradicted the evidence led. It's of course possible that the injuries occurred during asphyxiation or when Allison was rolled down the embankment, but to my mind at least it's entirely possible that Allison's death was the result of the hemorrhage (by whatever means) and not asphyxiation. I'm uncomfortable with a conviction based entirely on the exclusion of all other possibilities when evidence exists, even though it was excluded at trial, that potentially a scenario other than that put forward by the prosecution played out. I understand that Fuller QC was not authorised to make the decision to discontinue the prosecution in any case so no attack on his character is intended whatsoever.
All my opinion only and no disrespect intended, least of all to Allison. I hope that those who may have a different opinion can still understand where I am coming from.
