A QUARRY which was searched twice in the hunt for a missing mother and son is to be reopened.

Dalmagarry Quarry, situated off the A9 just south of Inverness, became the focus of the investigation into the disappearance of Renee MacRae and her three-year-old son Andrew almost 40 years ago.

Officers believed the bodies of the pair could have been buried there as the site was not far from where Mrs MacRae's burning BMW car was found.

However no trace of the mother and son were found and the site is now being reopened by quarry masters Pat Munro Ltd to provide materials for the dualling of the A9, which will start later this year.

Mrs MacRae's sister, Morag Govans, who lives in Inverness, said she was intrigued by the reopening.

She said: "I don't have a lot of hope but you just never know. I never thought that quarry would be opened up again."

Mrs MacRae and her son Andrew vanished in November 1976.

She had been travelling to meet her lover Bill MacDowell, an accountant in her millionaire husband's building company who was Andrew's biological father.

Her car was found burning in a layby near the quarry. A bloodstain was found in the boot and a murder inquiry was launched.

In 2004, a cold case review saw the quarry dug up again in a renewed search for the bodies but again nothing was found.

Brian Munro, managing director of Pat Munro Ltd, said: "The quarry does have a bit of a history. The police carried out a full excavation of the old quarry works and they were able to eliminate the quarry.

"We hope to open up later this year, in time for the first phase of the A9 works.

"That is the primary reason but we hope that it will have a life beyond that."
