The father of a British woman who was last seen entering a New Zealand hotel Saturday made a tearful plea for help Friday - but police said they have "grave fears" about the case.
Detective Inspector Scott Beard said a scene examination at the hotel is continuing and investigators were progressing with the viewing of hundreds of hours of CCTV footage.
A WICKFORD woman who has gone missing in New Zealand was last seen alive with a male companion, said police.
DI Beard said on Saturday: "Sadly the evidence we have gathered at this point of the inquiry has established that this is a homicide".
Speaking about the "location of interest" being searched at the hotel, he added: "I understand there will be lots of questions about what we are doing at the Citylife and exactly why we are there".
Police have released photographs of a necklace and a watch missing from the belongings Grace Millane left at the hostel where she was staying.
"The man is the same one who was named as a person of interest yesterday".
CCTV cameras captured Millane at the CityLife Hotel on Queen St at 9.41pm on December 1.
Her watch is a pale pink Casio Baby-G and her necklace is silver and features a green stone.
Police would like to hear from anyone who may have seen any of the items matching their descriptions over the past week.
"Several of her belongings, including her passport are missing and police believe it is likely that Grace has these items with her". The concern is that the family have not heard from her and when her 22nd birthday was on 2 December, that's when you'd expect to hear or for them to contact her so that's why there's concern.
He said Ms Millane had a number of phones on her while in New Zealand.
Millane called his daughter a "fun-loving, family-oriented daughter" and urged anyone with information to contact police.
The advertising graduate and keen artist arrived in New Zealand on November 20, after travelling through South America.
"We thought maybe it's just the time zone, sort of catching up, but we looked into it and realised her messages hadn't been read or delivered". Grace has never been out of contact for this amount of time and is usually in daily contact with either her mother, myself or her two brothers.
