Police have searched a property as part of their investigation into the disappearance of a man 10 years ago.
Gerard Conway was last seen in the Cookstown area at the end of January 2007.
He was reported missing a short time later, but despite extensive enquiries by police over a number of years, no clues as to his whereabouts have been discovered.
Detectives from the PSNI's Serious Crime Branch launched the search at an address at Battery Road in Ardboe, Cookstown, on Wednesday as part of the investigation into his disappearance.
They said the search followed new information provided to the investigation team.
Specialist resources were deployed, including police search teams, victim recovery dogs and a ground penetrating radar device.
However, once the search was concluded police said "nothing untoward was found."
Mr Conway was 32 when he was reported missing on January 25 2007.
Mr Talbot said his disappearance "continues to cause heartache and uncertainty for his family and friends who are heartbroken at not knowing what has happened to him".
"The passage of time has not eased this pain and I would appeal for anyone with information to get in touch with the police," he added.
Following his disappearance police checks were extended to the Republic and to England.
Police have CCTV footage of Mr Conway at a bank in Cookstown on January 25 2007 and there were sightings by people who knew him in late January and early February.
In the immediate aftermath of his disappearance, there were unconfirmed sightings in the Magherafelt, Toome and Ballymena areas.
Widespread search activity of the countryside around Cookstown, using dogs and aircraft, was unsuccessful.
"Because of the family's connections with the Republic, we have worked with An Garda Siochana to extend the appeal there but, sadly, to no avail," Mr Talbot said.
"After 10 years we still have no definite leads as to what has become of Gerard and we continue to appeal for information," he said.
"His family have made their own substantial efforts to locate Gerard and they deserve to know what has happened to him.
"Anyone with information, no matter how small, is asked to contact the police by calling 101.
"Alternatively, people can provide information anonymously to the independent charity Crimestoppers on 0800 555 111."
