Part 2
The same day a group from a Brisbane dive shop arrived at Santo and on 1 May 2013 they began diving with Aquamarine. The leader of this group (John) has advised me that the air they used was very bad and tasted extremely strongly of oil. This indicates that the compressor filters were not being replaced at the time they should be. The dive medical bible
Diving and Subaquatic Medicine (now called
Diving Medicine for Scuba Divers and available free on the internet at
Diving Medicine for SCUBA Divers) says that while oil in air will make you feel bad, it will not kill you. Generally the presence of oil in compressed air does not indicate that it contains too much carbon dioxide or carbon monoxide.
Laila appears to have done two more dives on this day (1 May 2013).
Anyway, John complained to the owner of Aquamarine, Mr Sayed, about the quality of the air supplied. He attempted to empty and refill some tanks but they still were tainted with the oil. In addition, it was reported to me that none of the tanks had been tested since about 2008 or so. John insisted that Mr Sayed get tanks from one of the other operators for them to use the next day. This happened and they had tanks owned by Santo Island Dive when they went diving on 2 May 2013.
The Fatal Dive
On Thursday 2 May 2013 Laila was again diving the wreck. She was still diving with Aquamarine and today was being guided by the same local Ni-Vanuatu guide (Simon Toa) as on her 30 April 2013 dive with Rob. She was the only diver with him. It was reported to me that Lailas tank was one owned by Aquamarine and thus, was probably carrying oil tainted air.
The dive plan was said to be to the Doctors Office (according to newspaper reports) although John believed they were going to The Lady. Whilst The Lady is a relatively simple dive (she is now at the front of the First Class Dining Room rather than at the stern end of this room), the Doctors Office is one of the harder dives in that it goes to a place almost in the centre of the wreck at a depth of about 42 metres. To get there you may even go to about 45 metres, although there are a number of routes that can be used. Personally I find it strange that they would agree to take Laila to either of these locations considering her apparent inability to dive in a correct orientation as well as the fact she ran out of air on a simpler and shallower dive two days earlier.
The following is based on statements given to the police as well as conversations I have had with people present on the day. Note that I am not convinced yet that parts of the story are accurate and I will explain this later.
I had assumed that they swam out a bit before descending, but this might not be correct. I based this on reports that give the time when the dive was called (see later). My description of the dive is based on how it is normally done and information in police reports. Visibility was reported to be about 10 metres on the day and the water temperature would still have been 28ºC.
Anyway, Toa and Laila descended and swam along the starboard side of the wreck (17 metres at first and then deepens on a slope) and entered the wreck via what is called Euarts Door. This is the door that was the main access door for passengers to enter the ship when she was tied up at a wharf. It is at 23 metres and leads into the Main Lobby. The First Class Dining Room comes off this lobby on the stern side. This should have taken no longer than five to six minutes.
From here you they travelled through the dining room and then to the Doctors Office. They would have gradually dropped from about 30 metres at the bow end of the dining room to 42 metres. This is a very small room where they would have ascended a metre partially into the room through the cabin door (the ship is on its side so the door is above you). In here they would have looked at the medical equipment and supplies that are still present over 70 years after the
Coolidge sank.
Simon Toa reported that when in here Laila indicated she could not dive any further (from police report). At this point I do not know if this is an accurate recording of what she indicated nor how she indicated this. It is also reported that this was 10 minutes into the dive. In my experience, this also indicates to me that they had started the dive right at the deco area and swum to the bow and down across the starboard railing of the wreck as I stated above. I base this on the fact that the last time I dived the Doctors Office (2007) I departed the room at 8 minutes but we had we had swum out further and entered via the area near the Swimming Pool which is a bit deeper. In 1999 when I dived this spot, we arrived at the Doctors Office at 9 minutes having started near the deco area.
As I have already mentioned, leaving the room at 10 minutes seems to mean that they left as soon as they arrived. Toa reported that they left the wreck and started back for the bow area. Presumably they went back through the dining room and then ascended up and out through Euarts Door. This would take 4 minutes at least.
When he checked behind him to see how Laila was going, she was not there. The police report does not make it clear when and where this happened, but I have been told by the former owner of Aquamarine that they were outside the wreck when this happened.
It seems that this was witnessed by another diver (his first name is Justin but he calls himself Jack I believe he might be American but perhaps living in Melbourne). I have attempted many times to speak to him via email and phone and actually spoke to him for a few seconds before the connection dropped out but there has been no discussion yet as to what happened. I am told that he told Rayman Lueng, owner of the hotel where Laila was staying, that he (Jack) saw Laila re-enter the wreck via Euarts Door. I have also been told this by John (the leader of the Brisbane group) who was also told this by Jack.
John told me that Jack saw Laila swimming back along the starboard side (the shallowest part of the wreck) and re-entering Euarts Door. As mentioned, this is the simplest way in and out of the wreck if diving The Lady and Doctors Office. It is not known why she did this. I can only speculate that she had dropped something (her torch? her computer?). In any case, it seems that she could not find her way out of the wreck. The time when she reached the spot where she was found, if all that was stated above did occur, was 17 minutes.
Note: the alternative to above is that Jack actually saw Laila entering the wreck at the start of the dive following Toa, but that Toa was not seen by Jack.
John told me that Toa said that when he looked behind for Laila, she was not there. This was said to be before he got to the bow. It is about 100 metres from Euarts Door to the bow, so assuming that he confirmed she was with him as they came out of the door and then again a minute later, I expect that he was probably approaching the bow when he again looked and noticed her missing. I would not assume that they were swimming beside each other as I very rarely see people do that when being led by a guide.
If this is what happened, then if Laila turned around soon after the first time she was checked on after exiting the door, she could have easily swum back to the door and re-entered before Toa would know she was missing. Remember that visibility was said to be only 10 metres, so a pair of divers swimming in opposite directions will be out of view in only a few seconds. I assume that Toa tried to find her but at this depth (probably 20 to 25 metres) he would not have had much time to look for her considering he would have already had a reasonable decompression obligation.
He also probably assumed that she had perhaps stopped to look at something and then not seeing Toa, had followed a different part of the wreck (say the railing) towards the bow or even perhaps dropped a bit deeper across the top of the forward holds. It would be almost impossible to try to refind a diver at this location in my opinion (remember I have done over 100 dives on this wreck).
No matter what, Toa then decided to head back to the bow area and ascend. I am certain that he would have had to do decompression by now. Of course he would have had to complete this before ascending as to do otherwise would have endangered his own life.
Once back at the bow area and then after ascending, Toa alerted the other staff of Aquamarine and customers that he was missing a diver. A dive guide with ear problems and John (who had just surfaced) swam out and snorkelled over the wreck. A short search would have been made to look for bubbles at the decompression site and over the wreck and also to check on any divers still in the water to see if she had accidentally got linked to another group (this can be common).
Finally, a number of divers went back into the water (David and Tulah dive guides) using three-quarter empty tanks and carrying unused stage bottles and they entered the wreck and found Laila. Toa did not go as he was said to be a quivering wreck (and he could not have considering he had only surfaced then). Laila was found near The Lady which is at 42 metres (140 feet) and not breathing. Her regulator was out of her mouth but she still had about 100 bar (I have also been told it was 50 bar but more have said 100, including John who looked at her gauge). Her finger nails appeared to have debris that would indicate she had scrapped at the inside of the wreck (witnessed by John).
Her dive computer was beeping and one of the people took it off her wrist (at least this is what has been thought to have happened) as the beeping was annoying them. It is also possible that her computer was found off her body (if she had dropped it). Her Suunto D9 dive computer has optional air integration, but from the video and photos I have access to, she does not seem to have a transmitter on her first stage.
Therefore, it is unlikely that the computer was beeping because she did not have enough air to complete the dive considering the decompression that would have now been required. The computer also indicates an error message if the bottom time is too long. I am not sure what is considered too long or if this also includes a beeping sound.
Laila was then brought towards the shore and John and perhaps another of the snorkellers took her body from the divers as they had decompression to do. From all reports she was missing at least 20 minutes before being brought to the surface. Her dive computer was handed by the divers to Rehan who then was witnessed giving it to the police. Rehan would not let John view the computer.
For the first 10 or 15 minutes after she surfaced, there was clear/white froth coming out of her mouth. Her mouth had froth coming out of it as soon as her body was brought to the surface. After the first ten or 15 it was intermittent as we managed to get a small amount of air into her lungs having pumped out all of the other foam (quote from John).
One of the other divers present diving with Aquamarine was an Australian anaesthesiologist (from South Australia) who started attempts to revive Laila. She and others attempted to get oxygen gear from the Aquamarine vehicle but there was nothing there. Meanwhile, someone made a phone call and as a result, Rayman Lueng (owner of Espiritu Hotel) or one of his staff, phoned an Australian called David Ellaby.
Ellaby is an intensive care paramedic who works for the Queensland Ambulance Service and also crews on the Sunshine Coast Helicopter Rescue Service helicopter. He was present in Luganville with a Christian group who are in the process of establishing a medical clinic. Ellaby was in town when he received the call and he hailed a taxi and headed to the clinic to grab some equipment. Meanwhile, the hotel sent a car to collect him and then took him and the equipment (including some drugs and a defibrillator) to the dive site.
On the way, Ellaby phoned the ambulance. It seems that they had not been called before this, although this may not be correct. Note that there is only one ambulance serving the whole island (almost 4,000 square kilometres) and it has no real medical equipment as would be found in an ambulance in the US or Australia and is normally only operated by a wardsman or at best, a nurse.
When he arrived at the site where the dive shops base their dives, Ellaby found the Australian doctor and the other divers still performing CPR. She was very glad to see him as he had far more experience in this sort of work than she did. Despite a lot of work, Laila never regained consciousness. The ambulance finally arrived 40 to 45 minutes after Ellaby called it, although this had no impact on the chances of Laila surviving.
The froth that was reported to come from Lailas mouth when she surfaced is an indication that Laila died from drowning.
At 12:05 pm, the police were finally called. The call came not from staff of Aquamarine, but from Mal Davies, the owner of another dive shop, Santo Island Dive. The police record that they arrived on site at 12:10 pm, but I personally think it would have been later considering the time taken to drive out to the site from town. There were a number of police officers who attended, but I am not sure who they were as the report does not even mention who the writer is. At least two were considered to be investigators, but you should be aware that the training and equipment they have is very basic compared to that of police in Australia.
At this time Lailas body was lying on the sand/coral beach and covered with towels. At 12:25 pm the police officer who wrote the report stated that he had completed his work.
Lailas body was taken to the hospital in Luganville (again this is very basic and really survives to a degree on New Zealand medical schools sending their partly trained doctors there for work experience). Here she was examined by a doctor and a Death Certificate (No 163) was issued by an unknown doctor who stated that Laila died from unknown cause awaiting corona (sic) report. The same day Senior Magistrate Rita Bill Navita visited the hospital and two days later he issued an Order for Buriel (sic).
The police seized at least some of the equipment involved in this incident. I believe that the dive computer and tank were taken (the computer was witnessed being handed to them). The dive computer is a very important clue to what happened, as it has an on-board memory that retains the profile of the dive. This can be viewed by accessing the log book function or, even better, downloaded via USB cable to a computer and viewed using certain software programs. This should be able to confirm if Laila did exit the wreck as said and when she re-entered it.
Testing the air would also show if there was a correct oxygen level and if there was too much oil, carbon dioxide or carbon monoxide. I have spoken to Dr Carl Edmonds (lead author of
Diving and Subaquatic Medicine) and he indicated to me that the normal physical observation of carbon monoxide poisoning, cherry red colour under the victims fingernails, is not very obvious in diving related carbon monoxide poisoning. Therefore, it is likely that if this is the problem, it would not have been noticed by David Ellaby (the paramedic), the female doctor doing the CPR or John. In fact, John has confirmed to me that there was no colouring and it seems that he specifically looked for this. Therefore it is unlikely that carbon monoxide poisoning is relevant to what happened.
On 11 May 2013 Lailas body was then taken to New Zealand. A post mortem was done in Auckland. I do not have any real indication of what was found other than on 13 May 2013 the Coronial Services Unit wrote to Lailas husband, Damien, and advised that the early result of the post mortem was unascertained pending investigations. Dr Edmonds also indicated to me that the blood samples should show if carbon monoxide levels were too high. Hopefully the full post mortem results will reveal something about this.
Alternative Scenario
The only real alternative to what happened as outlined above is that Laila never actually exited the wreck. This actually has a lot of credence, as based on the amount of air she used on the dive (120 bar), I cannot reconcile this with the dive as stated. For example, if she used air at the same rate that she used it on the dive on the wreck on 30 April 2013 (31 litres per minute), then she would have used 172 bar leaving 48 bar in her tank. Remember that when the tank was found it had 100 bar.
To fit the amount of air used into the timeframe as described by Simon Toa, I have used my dive in 1999 to the Doctors Office and then backtracked to end the dive at 17 minutes. To get the ending tank pressure of 100 bar for this dive, Lailas air consumption would have had to be 18 litres per minute.
Therefore, it seems impossible to me that Lailas air consumption improved from 31 to 18 litres per minute in only a few dives. The only solution to this quandary for me is that she died much earlier than has been reported. If I put her air consumption of 31 litres per minute into the scenario, she stops breathing at 11 minutes, not the 17 minutes that the reports indicate what happened.
