I'm a Rescue diver in Brisbane, Queensland, and I've been following the Inquest on the local news. QLD does indeed have the tightest regulations on scuba, and all inquests of this nature are very comprehensive, hence the 4 year delay. Most of the suspicious inconsistencies with this case have been mentioned previously, but I will add some details the investigation has announced to the Inquest:
- This was their honeymoon trip. The woman's greatest asset was her old car, and her life insurance policy, $30k worth, was known to be paid out to her father. Police are struggling to find a motive.
- The husband refused to come to Australia for the Inquest, the woman's parents are here and are present every day at the Inquest. This is despite the offer of free meals, accommodation and flights.
- No evidence pointing to faulty equipment was found, the woman's equipment was in perfect working order.
- I've read that her air was found turned on, even though she had asphyxiated.
- The man took 2 minutes to surface from 40', whereupon he started screaming for help, saying 'I've lost my wife'.
- The rescue diver took 1 and a half minutes to descend and return the body to the surface. As mentioned previously, the bottom can get to 80'
- Her mask & reg were in place
- Witnesses saw him give her a bear hug prior to the accident
- The other inconsistencies (ie current) have been mentioned previously.
By no means am I an expert, but if it was murder, I'm assuming he's given her a bear hug, switched her tank valve off and held her tight in a bear hug while she struggled as she asphyxiated. He's then switched her tank valve on, then started ascending to the surface to call for help, albeit ascending slowly so as to further decrease the opportunity for resuscitation.
What I don't get is the motive. Money is no motive, and they just got married....
