MORE organs from a North-East man found dead in a French country lane have gone missing.

A pathologist has found that one of Andrew Watt's lungs, part of his liver and his throat were not returned to the UK with his body.

It has also emerged that chemicals used to preserve organs that were returned after going missing mean tests cannot establish if they belong to the 31-year-old.

The discovery has caused further anguish for Mr Watt's family.

His mother, Julie Sheppard, said they had been left with no choice but to bury the organs with her son's body in the hope they were his.

Andrew Watt, from Durham City, was found dead about a mile from Vimarce, near Laval, in North-West France, in September last year.

French doctors decided that the former Durham Johnston School pupil died of heart failure.

His family questioned the judgement and a second post-mortem examination was ordered by North-East coroner Andrew Tweddle, who will conclude an inquest into the death.

After a three-month delay for the return of Mr Watt's body, it was discovered that his brain and heart were missing.

Organs thought to be Mr Watt's were found in a French research hospital and were returned to the UK.

However, the body parts were kept in formaldehyde, meaning DNA tests cannot prove if they belong to Mr Watt.

The discovery that other body part are missing has prompted Mrs Sheppard to again demand answers from the French authorities.

So far they have failed to answer her questions.

She has also been critical of the British Consulate in Paris for failing to help her get information from the French.

Mrs Sheppard said: "I'm absolutely exhausted.

"We are made to feel as if we have no right to ask these questions.

"I just feel let down."

Mrs Sheppard, who lives in Selkirk, in the Scottish Borders, has taken her case to her MP Michael Moore.

Mr Watt, who lived in France with his girlfriend, suffered from paranoid schizophrenia.

At the time of his death he was receiving treatment in a French hospital, however, his mother believes the medication dosages were far too high.

Last month, Mr Watt's family raised more than £1,800 with a charity walk along Hadrian's Wall in his memory.
