Jenny Methven murder: Search warrants granted to police
Police investigating the murder of an 80-year-old widow have been granted warrants to search the house and vehicle of a named individual.
Jenny Methven was found dead in the kitchen of her isolated cottage near Forteviot, Perthshire, on 20 February.
She had been beaten on her head and body with a blunt object. Her body was discovered by her son, David.
A planned Crimewatch appeal was called off after police said there had been a "significant development".
The warrants were granted by Perth Sheriff Court.
It is believed the sheriff would have been presented with initial "evidence" making the named individual a "person of interest" in relation to the ongoing murder inquiry.
Tayside Police had been scheduled to make a public appeal on Crimewatch exactly a month after the popular pensioner was found dead in her home in Forteviot, Perthshire.
Det Ch Insp Colin Gall, who is leading the investigation, confirmed the force had pulled out of the TV show to avoid potentially prejudicing ongoing inquiries.
A spokesman for the force said: "Tayside Police can confirm that detectives investigating the murder of 80-year-old Perthshire woman Jenny Methven are currently following significant lines of inquiry."
Earlier, Det Ch Insp Gall said: "Whilst I am not in a position to elaborate any further at this time, I can confirm that there have been further developments this week and our inquiry has now reached a critical stage.
''As a consequence of this we will not be in a position to make an appeal on Crimewatch tonight as had been planned. We are hugely appreciative of the assistance given to us by everyone involved with the programme."
Det Ch Insp Gall said detectives had informed Mrs Methven's family of the latest developments.
A £10,000 reward has been offered for information leading to a conviction.
In the past few weeks, the inquiry team have interviewed hundreds of people and reviewed "days' worth" of public and private CCTV footage.
More than 400 items have also been examined by forensic officers.
Mrs Methven was seen alive as she walked her two-year-old spaniel on roads near her home at Kildinny Cottage between 08:00 and 09:00 on the day she was killed. She was wearing a fluorescent yellow jacket.
The pensioner was last heard from at 10:30, when she ended a phone call with a friend saying she could hear a vehicle coming up her driveway
Her son found her body in the kitchen of the cottage at about 17:15.
She was found slumped at the kitchen table with a bloodstained towel wrapped around her head, with her dog in his cage in the next room.
