Dunfermline mum Nicola Urquhart has slammed police investigating her son's disappearance in a scathing social media post. 

Corrie McKeague went missing six months ago in Bury St Edmunds but his mum has raised concerns over mistakes made by those handling the case.

Nicola said she was grateful that police were searching the landfill site but insisted that it should have started five months ago. 

She also criticised Suffolk Police for their unfounded claim that they secured the site from the start of investigations there.

Her son, Corrie, is believed to have ended up inside a refuse lorry that was then dumped at the landfill site that is now being searched.

Nicola wrote on Facebook: “Sadly there is quite a lot of confusion with what we were told and what we are being told now.

“We were told the bin weighed 11kg and now we're told it's 116kg. There is also a huge issue with the police claiming on live tv that THEY secured the landfill from the start and ensured no more rubbish was put on top.

“This is not true. They handed back the landfill and were done. Regardless of my efforts in having military talking to the assistant chief constable on my behalf begging them not to do this.”

The refuse lorry was included in investigations from the beginning after it was discovered on CCTV being near the last place Mr McKeague was seen.

Despite initial suggestions that the load of the lorry was 11kg, police said it was found to be more than 100kg. Forensic examinations previously found no traces of Mr McKeague in the lorry.

 The search of the landfill site in Milton, Cambridgeshire will take six to 10 weeks, covering around 920 square metres up to a depth of eight metres, police said. It follows work to move 8,000 tonnes of bulk material to make the area safe to search.

Talking of the emotional drain the search is taking, Nicola wrote: “Every minute they take to do this, there is a mother staring at her phone hoping for it to ring and praying that it won't.”

Suffolk Police announced today(March 24) that the Health and Safety Executive will be working alongside officers investigating Corrie McKeague’s disappearance.

Detective Superintendent Katie Elliott said; "Officers have been liaising with the HSE as part of the investigation into the circumstances around what happened to Corrie.

"At this stage our search at Milton continues. If there is a find on the site then the HSE will have a role to play in looking into the procedures that were in place and we have been speaking with them to ensure they are aware of our investigation to date.

"Officers have completed thousands of hours of enquiries to find Corrie and through the work that has been completed over the past few months we have gathered a substantial amount of information which will inform both our own and any potential HSE investigation as we move forward.”
