Caroline Graham: Specialists called after search by dogs
Police searching for the body of a murdered teenager have called specialist forensic scientists to a house in County Armagh.
Officers have been using dogs trained to find human remains in the search for Caroline Graham, 19.
She had been living in Hanover Street, Portadown, when she vanished in 1989.
A fresh search of the house began on Monday and as a result of "indications" by the dogs, scientists have been asked to examine some items in the property.
It is understood that the items are not body parts.
A police spokesman said the house search was continuing on Tuesday and is expected to run into a third day.
Ms Graham, who is originally from Newry, County Down, was living with her boyfriend at Hanover Street at the time of her disappearance.
Officers have carried out a number of searches in the Portadown area over the years, but Caroline's body has not been found.
A murder inquiry was launched in August 2012 after police said they had a number of new lines of inquiry.
The house search is being conducted with the consent of the current owner who, police believe, has no knowledge of the events of 1989.
The officer leading the investigation, Det Ch Insp Peter Montgomery, said on Monday that Caroline had been for a night out in Banbridge, County Down, with a girlfriend on the evening before she went missing.
She had stayed part of the night in a hostel in Portadown, but was gone in the morning.
Ch Insp Montgomery said police have information that she returned to Hanover Street to get some clothes. She has not been seen since.
"I believe she was murdered some time later and that her remains are somewhere in Portadown," he said.
"All our inquiries lead us to believe there is more than one person who knows exactly where Caroline is buried. We need them to come forward and tell us exactly what they know."
The detective added that two men, possibly off-duty soldiers, who gave Caroline a lift in a black Ford XR3i on the night before she disappeared had yet to come forward.
He said the men are not being treated as suspects, but need to come forward.
