A man has been convicted of murdering his wife who went missing four years ago and whose body has not been found.
Tina Baker looked after animals at the farm as a hobby
Tina Baker, 41, was last seen in 2002 leaving her new lover's home to feed animals at the farm in Chobham, Surrey, which she had shared with her husband.
Police inquiries included seeing if her remains had been fed to their pigs.
Martin Baker, 54, of Ayebridges Avenue, Egham, denied killing her, saying he knew nothing of her disappearance. But he was found guilty at the Old Bailey.
Baker was remanded in custody for sentencing later this month.
Mark Dennis QC, prosecuting, said circumstantial but "very powerful" evidence pointed to him having killed his wife and disposing of her body and car.
Det Supt Brian Russell said after the conviction: "We do not know how she died.

"He could have fed her to the pigs, he could have buried her or dumped her in water."
Pigs' swill and manure at the farm was checked after Baker's first wife, Gillian Hopkins, told police of threats he made before their divorce.
She claimed he said he would make her "disappear permanently" by cutting her up and feeding her to the pigs.
Martin Baker was described as a controlling and jealous man
An Old Bailey jury was told the defendant feared losing £100,000 Brookfield Farm in Chobham after his wife had walked out on him and moved back in with her parents.
Mrs Baker left her new lover's house in Sunbury to drive to the farm on 8 July, 2002.
Her husband denied being there, but witness Fiona Cooper, who arrived at the farm on the same day to tend to a horse in a nearby field, told how she was ushered away by an "agitated" Baker.
Mr Dennis told the court: "He immediately told her she couldn't stay... she was left feeling that he couldn't wait to get rid of her."
Mrs Baker's disappearance was not reported to police for three weeks.
Det Supt Russell said: "She had just vanished off the face of the earth.
"We will be hoping to speak to Martin Baker to ask him to reveal where Tina's body is."
