Bob Woolmer with his lethal combination of morbid obesity,severe hypertension ,coronary artery disease and diabetes mellitus was a walking time bomb ready to explode anytime and thats exactly what happened. People with lesser risk factors than Bob drop dead every single day.
The poison theory was injected to explain lack of struggle by Big Bob at the scene, yet lacked any toxicology support.
The theory that alleged killers were sophisticated enough to import poison; were able to slip tasteless,colorless, untraceable poison(a perfect poison,which is a myth;Don't try it)into Bob's drink,yet were stupid enough not to put enough poison to kill him instead elected to incapacitate him,then returned to the scene of crime to finish him off,yet again botched up the strangling job and left him alive since according to Police report Bob Woolmer was found unconscious in the hotel room and he died in the hospital. All these bizarre theories simply defied common sense.
Jamaica Policea acted professionally by keeping all options open once they were told by pathologist that there was likelihood of a murder,yet acted competently by obtaining a second opinion before charging anyone.
Since pathologist's opinion was not supported by second opinion,does not mean he acted in a bad faith.To err is human.
