THE family of the man convicted of murdering Suzanne Pilley has claimed the case contained “flawed evidence” and demanded it be reassessed by a different police officer.

Pilley, 38, disappeared from Edinburgh on her way to work 10 years ago on May 4, 2010.

It is believed she was murdered in the basement of Infrastructure Managers Ltd in the city and her body buried in a forest in Argyll.

Her former boyfriend David Gilroy was found guilty of her murder but Pilley’s body has never been found.

Gilroy, 57, is serving a life sentence with a minimum of 18 years.

For the 10-year anniversary of Pilley’s disappearance, Police Scotland launched an appeal asking for anyone who may have information that can assist with the inquiry to find her body but has yet to come forward to do so immediately.

Benny and Linda Gilroy – the murderer’s father and step-mother – maintain his innocence and have now written to Police Scotland chief constable Iain Livingstone to demand the case be assigned to a different officer for reassessment.

They have also accused Police Scotland of not allowing their own expert reasonable access to the original CCTV footage used in the trial.

In the letter, the family said: “How can the original officer have a truly open mind about this even if he wanted to?

“If he produced flawed evidence, he is hardly going to have the motive to expose that to public scrutiny.

“The flaws we wish our expert to check against the original footage are most obvious in relation to what was taken from cameras in and around St Andrew Square, Edinburgh.”

The Gilroys added: “We would also like to say that if we thought for one minute that David had committed such a heinous crime, we would certainly be asking him to put the Pilleys’ minds at rest.”

A Police Scotland spokesman said: “We can confirm we have received a letter, sent to the chief constable, and it will be replied to in due course.”
