The mother of a British holidaymaker who vanished in Sardinia says she is still "living in limbo" five months after her son disappeared.
Michael Frison, 25, from Chard, Somerset, went missing in the northern part of the Italian island on 13 July.
"My heart is broken without Michael," said Cristina Pittalis, who has climbed mountains and searched caves and rivers to find her son.
Despite a huge search operation involving drones, a helicopter, a mountain rescue team and volunteers, Mr Frison has not been found. His mother is now urging a woman from Jersey to come forward, as she believes she may have answers that could help an Italian criminal investigation.
