RECORDINGS from the inquest of Fenland man David Gray - who died after a massive overdose at the hands of a German locum - have gone missing.

The lost data came to light after the lawyer of Mr Gray’s sons Stuart and Rory asked for a transcript of the hearing, which was held at Fenland Magistrates’ Court in Wisbech earlier this year.

However, he was told that the recordings had gone missing following a malfunction on the laptop on which they were stored.

A coroner’s officer told the solicitor in a letter: “Following an examination by the county council IT department it appears that the recording software had suffered a a malfunction and the recording cannot be retrieved.”

Mr Gray, from Manea, died in February 2008 aged 70 after German doctor Daniel Ubani injected him with 10 times the recommended dosage of diamorphine.

Dr Ubani, who was working for an out-of-hours medical service at the time, was on his first shift in the UK

Of the lost data, Rory Gray said: “The transcript of this inquest hearing is of far greater significance and value than normal because it is the only hearing and examination of evidence that has been held in any country into the killing of my father.”

Cambridgeshire County Council, which owns the recording equipment used at the inquest, and the Coroner’s Office are carrying out a review into the matter and hope to have it resolved by September 30.

Earlier this year Dr Ubani was struck off by the General Medical Council because of concerns over his competence. Last month, he failed in an attempt to gag Mr Gray’s sons and now faces an investigation from his employers, the local government at Arnsberg, Germany. It had previously refused to hold such an inquiry.
