The shocking case of missing mum Nicola Bulley has captivated the nation.
Ms Bulley, 45, went missing on January 27 while walking her dog in St Michael's on Wyre, Lancashire. The dog was found wandering alone, while her phone and the dog's harness were on a nearby bench. There was no trace of Nicola.
The river has been searched, CCTV cameras have been checked, passersby have been interviewed, and yet there appears to be no new information as to her whereabouts.
Sadly, it's all too common for people to seemingly vanish into thin air.
In the UK, someone is reported missing every 90 seconds, with 170,000 people reported missing each year. More than 70,000 of those are children, according to the charity Missing People.
Thankfully, statistics show that most people are found within 24 hours, but at the end of March 2020, there were 5,300 people who had been missing for a year or more.
Here, The Mirror takes a look at the tragic cases of those who never came back...
Sheila Fox, 6
Sheila went missing on her way home from school in August 18, 1944.
Dubbed the 'girl in the green coat', she was last seen outside a local bakery in wartime Bolton with a strange man on a bike.
Witnesses claimed she was riding on the handlebars at one point, and when one passerby asked her what she was doing, she replied: "Going with this man."
For 60 years, the case went cold. Then police received a tip from a local who had seen a man digging in his garden at the time Sheila went missing.
The garden was excavated but nothing was found.
Her family never gave up hope they would one day learn the truth.
Sheila's older sister Rene said: "I will be so glad if they find her because it was all so sudden. It left us all feeling so empty. It was a terrible time.
"We never even found her shoes or a ribbon. It was as if the earth had swallowed her up. It would be such a comfort if she could have a Christian burial."
Tapiwa Matuwi, 21
IT graduate Tapiwa disappeared after a night out in Swansea, Wales, on February 7, 2019.
The hip hop artist had been to the city's Fiction nightclub with friends and was last seen on CCTV walking by the marina at 7am.
After that, he vanished.
For his family, the pain of not knowing what happened to their son has been unbearable. They held a concert, posted flyers and launched appeals, but there were never any leads.
"We are scarred forever, we have an important part of our family missing," his father Munyaradzi Zvada told the BBC.
"There is the CCTV, and then no information, it is like a wild goose chase. I know somebody knows something or saw something, but no-one is saying anything.
"It is a busy area, people are always walking their dogs, somebody out there knows something, why would they withhold that information?"
Claudia Lawrence, 35
No one has heard from chef Claudia Lawrence since she called her mother Joan on the evening of March 17, 2009.
She vanished from her home in Heworth, York, and was reported missing by her father, Peter, when she failed to arrive for work at York University the next day.
The disappearance remains unexplained and is now treated by North Yorkshire Police as suspected murder.
Tragically, her father died in 2021 aged 74 without finding out what had happened to his daughter.
Mr Lawrence spearheaded a nationwide search for his daughter Claudia, which cost police around £1m over the last decade.
Nine people have been questioned, but no charges have ever been brought.
In 2022 a mysterious floral tribute claiming that Claudia is "in the water" was found near a beauty spot. While the exact location wasn't revealed, it's understood the tribute wasn't discovered at Sand Hutton gravel pits, near York, where investigations took place last September.
Elizabeth Chau, 19
Nineteen year old Elizabeth was last seen handing in a university assignment in April 1999.
The 'considerate' and 'responsible' Vietnamese student was recorded on CCTV walking past west London's Ealing police station on her way back from Thames Valley University at 6pm.
She was just a mile away from her home.
When she didn't arrive back, her family instantly knew something was wrong.
In an interview in 2012, her brother Minh Chau said: "She was a very responsible girl and would always contact us if she was going to be late."
Lola Shenkoya, 27
A lack of witnesses stymied the investigation into Elizabeth's disappearance, then just nine months later computer graduate Lola Shenkoya, then 27, went missing from the same road after returning home from work.
Locked out of the house because her sister had the key, Lola is said to have caught the E2 bus to Haven Green and got out by Burger King by Ealing Broadway Tube station.
She was never seen again, and her bank accounts have never been touched.
Serial rapist Andrezej Kunowski, who was dubbed 'The Beast', was grilled by police due to his history of operating in the area.
The now deceased monster was jailed for raping a student, and is believed to have committed at least 17 rapes in Poland. He murdered 12-year-old Katerina Koneva in her west London home when she returned home from school.
A lack of evidence meant he was never charged over Elizabeth and Lola's disappearances. They remain missing to this day.
Peter Baglin, 55
Grandfather of four Peter left home to go on his 'favourite walk' along Bridgewater Canal on December 28 last year and never returned.
He was last seen at the Texaco garage on East Lancs Road in Mosley Common in Wigan, Greater Manchester, at 7.38pm.
On the morning of December 29, his phone, hat and headphones were found on the towpath of the Bridgewater Canal, Greater Manchester Police said.
His wife Michelle reported Pete missing after quarter-hourly phone calls to him remained unanswered.
Officers deployed a number of resources, including underwater search and rescue, mountain rescue and drones.
Michelle also organised searches of the entire stretch of the canal, with over 200 people attending to help - but to date, there haven't been any results from the searches.
Michelle said: "It's a very surreal feeling. It's like it's happening, but it's not happening to me. I never thought I would ever be in this position and I just want Pete home.
"I am convinced that there is someone out there who knows where he is. He is instantly recognisable by the tattoo of 'Michelle' on the left side of his neck and I'm urging anyone who may have seen him, or been with him, to get in touch. I just want to know he's okay."
Genette Tate, 13
Genette vanished on her newspaper round in her home village on August 19, 1978.
Her disappearance sparked the biggest missing persons inquiry launched by British police – but her remains have never been found.
For four decades her devastated dad John tried to learn what had happened to Genette, who vanished from Aylesbeare near Exeter, Devon. he died without knowing in 2020.
Devon and Cornwall Police held a cold case probe into the murder several years ago and their 'only suspect' was Scottish serial killer Robert Black.
They had been days away from charging him when he died in an Irish jail where he was serving a life term for child murder.
John, in his last main interview in 2018, said: "My life is coming to an end. I dearly want to know where Ginny is.
"To know she has been found and given a Christian burial would be enough.
"I could go to my grave in the knowledge we were together again.
"I'm not 100 percent sure Black did it. If we could find her body that would give me proof."
Mary Flanagan, 16
Mary Flanagan was 16 when she vanished on New Year's Eve, 1959.
Mary, of West Ham, East London, kissed her siblings goodbye and said she was going to a party in Newham with friends from the Tate & Lyle factory.
It later transpired that she hadn't been to work for two weeks before her disappearance, and that she was besotted by a seaman called Tom McGinty.
Despite testing the DNA of 100 bodies, Mary has never been found - and neither has Tom.
One theory is that she fell pregnant by Tom and ran away to have the baby.
Recalling the last time she saw her, Mary's sister Brenda said in 2020: "We all think Mary might be embarrassed after all this time, or worried if she got in touch she might be rejected, but that's not going to happen.
"She is welcome in our lives and we want her with us.
"Dead or alive, we just want to know so we can be together, or we can grieve."
