Police have been trying to locate where a newborn baby discovered dead at a recycling centre in Suffolk might have been placed into a bin.
The girl was found at Sackers yard in Needham Market on the afternoon of 14 May, and is believed to have arrived along with rubbish from the Ipswich area.
The site will be released back to the waste management company tomorrow, Thursday 4 June, after three weeks of searches.
Alongside forensic work, officers have been studying CCTV from 52 commercial waste collection locations.
Police remain unable to locate the baby's mother, and have issued a fresh appeal to find her.
A statement from Suffolk Constabulary said: "Detectives remain concerned for the wellbeing of the baby’s mother and while they have made every attempt to trace her unfortunately, this has not yet been possible.
"Anyone with any information that may be able to help identify her or with concerns for a recent mother or mother-to-be, is asked to come forward as soon as possible."
Enquiries have taken officers to over 800 residential and business premises in the Ipswich area, and posters have also been handed out.
