The heartbreaking mystery of Baby A, one month on: "Our determination to get answers is unrelenting"

It is a piece of perished pink fabric. But it has huge significance in potentially solving a tragedy.

The material is thought to have been used to wrap around a baby whose remains were found a month ago on the edge of a snow-covered field. Scientists are hoping to find DNA on it which may be from the child's mother, grandparent, or a relative.

Concern remains for the welfare of the child's mother who will be in a distressed state and in turmoil trying to cope with the trauma which led her to leave a tiny scrap of humanity on land just off a main road. Bouquets continue to be placed at the scene by the public including a single red rose in a plastic domed container to protect it from the harsh weather. It has the message 'Rest in Peace Baby A you're in our hearts'.

Baby Ava was discovered by a dog being taken for a walk at Ashtons Field, Little Hulton, Salford. The dog stopped in its tracks just inside the field off Cleggs Lane, which is next to a layby.
