A father says he'll 'never stop looking' for his missing daughter and will find her whatever it takes.
Catrin Maguire was last seen in Anglesey, north Wales on November 15 last year.
The 22-year-old university student from Holyhead vanished leaving her family desperate for answers to her mystery disappearance.
Five months since she was last seen her dad Gerry has reinforced his commitment to finding Caitlin "whatever it takes".
He told NorthWalesLive: "The not knowing is very distressing. It's devastated our family because we've got no idea where she is or what happened.
"How can someone just disappear off the face of the earth with no trace whatsoever? We're hoping someone has seen something, maybe saw Catrin on that day and could help us get answers."
The young woman was a month into her third year at Bangor University studying health and social care when she went missing.
She grew up in Anglesey with her parents Gerry and Wendy and younger brother Ciaran, who have been "devastated" by her disappearance.
North Wales Police issued numerous appeals following Catrin's disappearance, including a CCTV image which showed her walking along a street towards secondary school Ysgol Uwchradd Caergybi on November 15.
A doorbell camera reportedly captured an image of Catrin walking past the school, towards the Llaingoch area and the last confirmed sighting was at 1.18pm, when she was seen walking past the RSPB Cafe in South Stack.
Investigations by North Wales Police revealed Catrin had bought a return train ticket from Bangor to Holyhead earlier that morning and arrived in Holyhead at around 11.30am.
Crews from Mon Search and Rescue, Search and Rescue Dogs Wales (SARDA), the coastguard and RNLI volunteers searched for Catrin in the days that followed but found no clues as to where she might be.
Gerry said: "There was a massive air and sea search rescue, and volunteers from the RNLI went above and beyond for days and weeks afterwards, but there's just no sign of her.
"It's been months now and it's absolutely devastating our family, even when we celebrate milestones like birthdays or anniversaries, it hits home that Catrin isn't here.
"It's killing me, I can't get away from it. I don't know where I am half the time."
Desperate for any information that may help them understand what happened, Catrin's family have once again appealed to anyone who was in Holyhead on November 15.
Her father hopes holidaymakers may lead them to answers.
He said: "Holyhead is a seasonal place with lots of tourists so maybe there were people staying in caravans or mobile homes who may have seen something.
"They may not be from North Wales but if anyone was visiting the area at the time, they may have seen Catrin there. One thing's for sure, we will never stop looking and fighting to get answers."
A NWP spokesperson said: "North Wales Police confirm that Catrin remains missing and continue to encourage anyone who saw Catrin at South Stack, Holyhead on the afternoon of November 15, 2021, or who may have any further information on this missing person to contact us."
Catrin is approximately 5ft 5in tall, of slim build with long, dark hair.
If you've seen her or have any information, please contact North Wales Police on 101.
