I first met Dr David Moor a number of times in the late 1990s and he always struck me as a decent chap whose intentions were good.

The north east GP first hit the headlines when he was accused of killing retired ambulanceman and cancer patient George Liddell, 85, by injecting him with a lethal dose of diamorphine.

He had a lot of support from his patients and they set up various fundraising campaigns for his legal costs – one woman actually posed naked for a national newspaper and donated her fee to the cause.

I attended one of the fundraising events in September 1998 and The Journal used this photo.

As the trial approached the national newspapers took an interest and The Express used this photo from the fundraiser to illustrate its coverage of the court case.

He was eventually cleared of the charge and I was asked by the Mail on Sunday to do some portraits of him and is wife. It made sense to get some shots of him hacking down the country lanes near his home on his horse.

I was sad to hear that friends said he never recovered from the stress of the epic court case and he later died suffering a suspected heart attack in October 2000.
