At the beginning in this case detectives sought the help of a TV Cracker-style psychologist, and they had not ruled out DNA testing the whole village.
One village shopkeeper, who didn't want to be named, said rumours were flying thick and fast, with everyone saying the police didn't have a clue.
Det Supt Stephen Heath, the officer in charge of the inquiry, said that new leads were emerging.
DS Heath refused to give details but revealed that extra police officers from other divisions were being drafted in to Galston for door-to-door inquiries.
He said it was vital to interview people as quickly as possible before they forget what they may have seen on the day of the murder.
THE detective leading the hunt for the killer of a 91-year-old grandmother yesterday said he had never been so outraged.
Detective Chief Inspector Willie Prendergast spoke after seeing Margaret Irvine lying on the living room floor of her home in Galston, Ayrshire, on Sunday evening, bound and beaten to death.(Mrs Irvine was found on her bed)
The detective believes that someone walked unhindered into her home because she had left her door unlocked.
Detectives said they were unhappy with the poor response from local people in their appeal for information to track down the killer.
Detective Chief Inspector Willie Prendergast said the inquiry team had received just 20 calls but that door-to-door inquiries and forensic tests were continuing.
And he revealed that the investigation would be making extensive inquiries in Galston next Sunday - a week since the pensioner's murder.
This was a callous crime committed by someone who must be showing a mood change to their personality DCI Willie Prendergast
"My own opinion is that there is someone out there with knowledge," he added.
"This was a callous crime committed by someone who must be showing a mood change to their personality.
"The thing is that some individual knows this person and will recognise change."
