The death of Dr. David Kelly, a former weapons inspector in Iraq, was “murder” and not suicide, according to a drug expert who spoke with British authorities during the ensuing investigation.

Dr. Andrew Watt, quoted prominently in the Saturday edition of Britain’s Mail Online, is attributed as “an experienced clinical pharmacologist” who reportedly spoke to authorities after Dr. Kelly’s death and assurred them it was not due in part to an overdose, which was later cited as one of the causes.

“I reported to the Thames force that I believe that the death of Dr Kelly may have been murder,” he reportedly said. “I have received an acknowledgement and they have given me an incident number. I have been told that the inquiry is being conducted by a very senior officer.”

Dr. David Kelly was found dead in a field near his home in Oxfordshire in 2003, shortly after he was revealed to be the source of a BBC leak that accused Tony Blair’s government of exaggerating the threat posed by Saddam Hussein. His death prompted suspicions among many that he may have been killed in retaliation for the leak.

Kelly himself had predicted he would be “found dead in the woods” if the UK invaded Iraq.
