Mother and son held over murder

Attracta Harron was last seen walking to Mass

Police have been granted a further nine hours to question a woman about the murder of a County Tyrone pensioner.

Attracta Harron, 65, from Strabane, disappeared three months ago while returning from Mass in Lifford, County Donegal.

Her body has never been found.

The 53-year-old woman was arrested on Friday and her 21-year-old son was arrested at his Sion Mills home on Thursday.

The police are continuing to question him at Antrim Police Station.

A number of items seized at the man's home are also being examined.

A police spokesperson said they were keeping an open mind on a possible motive, but it was not believed to be sectarian.

Major search

Despite a major police operation involving specially trained dogs and divers in rivers around Strabane, Mrs Harron's body has not been found.

The police staged a reconstruction of her last known movements, with a female officer wearing similar clothes walking the same route as the pensioner.

Detectives issued a number of appeals in an attempt to trace two motorists.

A red hatchback with a southern Irish registration plate was seen at Greenbrae about 1130 GMT on 11 December.

Detectives also want to trace a driver of a red-coloured car which sped past a tractor and trailer at Orchard Road, heading towards the border at about the same time.

Fourteen detectives have been assigned to the case.

They have been working closely with Gardai across the border in County Donegal.
