A witness who offered testimony supporting the theory that Laura Letts-Beckett may had drowned after fainting told a Kelowna jury there was just as much evidence for the idea she was pushed into the water.

Dr. Matthew Orde, a forensic pathologist with the UBC Faculty of Medicine, was cross examined by Crown counsel Iain Currie Wednesday, as defence of the New Zealand politician charged with killing his wife continued.

In a report on the case, Orde detailed a number of reasons why Letts-Beckett may have died in the water Aug. 18, 2010, while boating with her husband Peter Beckett in remote Shelter Bay on Upper Arrow Lake.

Cold water shock 香蕉视频直播� the process of someone gasping when they find themselves in cold water and sucking in cold water 香蕉视频直播� was among the possibilities he listed.

香蕉视频直播淒o you have any evidence that cold water shock was a significant factor?香蕉视频直播� asked Currie.

香蕉视频直播� No I don香蕉视频直播檛. I can simply raise it as an issue,香蕉视频直播� Orde replied.

香蕉视频直播淕iven the available literature, if a jury were to conclude that the water was 20 C or above when Ms. Letts-Beckett went in the water, would you agree there would be there would not be a likelihood of cold water shock?香蕉视频直播� Currie asked.

Orde couldn香蕉视频直播檛 support that theory definitively, so Currie asked him to translate what he did believe into 香蕉视频直播渓ay language.香蕉视频直播�

香蕉视频直播淐old water shock is a thing 香蕉视频直播� one. And two, it may or may not have happened here 香蕉视频直播� yes?香蕉视频直播� said Currie.

Orde agreed to that.

Currie also challenged Orde香蕉视频直播檚 theory that heart issues may have played a part in Letts-Beckett香蕉视频直播檚 fall into the water. Part of the evidence in the background of that theory was that Letts-Beckett allegedly had told her husband, Peter Beckett, that her back hurt.

香蕉视频直播淚f an otherwise healthy woman reportedly said her back was sore, out of 10, what mark would you give a first year medical student if they suggested the diagnosis of fatal arrhythmia?香蕉视频直播� Currie asked.

Orde pointed out that if she hadn香蕉视频直播檛 died it clearly wouldn香蕉视频直播檛 be a fatal condition, and said his job as a pathologist was to try and delve into any underlying factors that may have caused her to plunge in the water and ultimately die.

The back ache and potential arrhythmia fit into that category of thinking, he told the jury.

香蕉视频直播淲ould you agree with me that sitting on a cooler on a thin cushion and a life-jacket would likely be uncomfortable?香蕉视频直播� Currie asked.

Orde said as a pathologist, he couldn香蕉视频直播檛 answer that question but as a person he could imagine it would be uncomfortable.

Currie also pointed out that Letts-Beckett香蕉视频直播檚 parents lived into their 80s and her siblings were alive well into their 40s and 50s without any evidence of a heart condition, which is a factor that should be considered when assigning potential heart health diagnoses to a person.

Ultimately, said Currie, there was no medical evidence that Letts-Beckett had an underlying cardiac condition. The same goes for the theory that she fainted and fell into the water.

香蕉视频直播淚f Ms. Letts-Beckett was pushed into the water, you wouldn香蕉视频直播檛 expect to find forensic evidence of that either?香蕉视频直播� said Currie.

香蕉视频直播淚 would not,香蕉视频直播� said Orde.

香蕉视频直播淵et you haven香蕉视频直播檛 listed that possibility anywhere for the jury to consider as a possible contributory factor?香蕉视频直播� said Currie.

Currie later pointed out that there are many circumstances where a person falls in the water and doesn香蕉视频直播檛 drown, not the least of which being when someone is nearby and reaches out to help someone onto a boat.

Beckett, now 60, denies murdering second wife Laura Letts-Beckett. He was arrested in August 2011 and charged with murder and Crown counsel is attempting to prove he killed her intending to claim on a life insurance policy he had taken out in her name.
