The Cork woman (47) vanished without trace on March 20, 2017 – and no trace has been found of her since then despite multiple searches and trawls of dozens of hours of hours of CCTV security camera footage.
Now, gardaí are to launch a major appeal in the hope it might trigger someone’s memory of a vital piece of information.
A senior detective insisted gardaí remained convinced Ms Satchwell never left Ireland – and that the clues as to what happened to her lie in the east Cork area.
Ms Satchwell disappeared from her home in Youghal, Co Cork, on March 20, 2017.
Despite a massive Garda investigation that included 400 lines of inquiry, 100 hours of CCTV footage and 170 statements, no sign of Tina has been discovered in almost five years.
All leads in the case so far have failed to yield any clue to help solve the mystery over what precisely happened to her in 2017.
Gardaí have no plans, as yet, for any further major searches following major operations off the Youghal coast and in an east Cork woodland.
Ms Satchwell was last seen by her husband, Richard, on March 20, 2017, when she asked him to leave their home on an errand.
She was not at their home when he returned a few hours later and he presumed she had gone to stay with her family.
He reported her missing four days later.
A huge Garda search operation and an analysis of hours of CCTV security camera footage has failed to yield any clue as to what happened to her.
Ms Satchwell did not have a passport – and there was no indication she had bought tickets to travel overseas by either plane or ferry.
“At this point, all the indications are that Tina never left Ireland,” a Garda source said.
Gardaí searched CCTV footage from all Irish ports and airports, including those in Northern Ireland with the assistance of the Police Service of Northern Ireland (PSNI), without any sighting of Tina being found.
UK police have also checked for signs of Tina at their ports and airports – and at locations in northern England where she used to live.
All such searches have yielded nothing.
Mr Satchwell previously said there was nothing out of the ordinary on March 20, 2017, to indicate his wife was about to disappear.
“It was the same as any other morning – she got up and I made her a cup of tea and a slice of toast. It is something I will never forget,” he said.
“It wasn’t unusual for her to turn around and ask me to go shopping. I thought nothing of it at the time. When I came back, the keys were on the ground. When she didn’t come back I thought she was gone to Fermoy.”
He raised the alarm four days later when he realised, to his shock, that she had not gone to visit relatives in Fermoy.
Two suitcases were missing as well as items of Ms Satchwell’s clothing from the Youghal property. However, her beloved dog, Ruby, was left alone in the house.
Mr Satchwell also claimed that €26,000 in cash – saved from a property sale and the proceeds of car boot sales – was missing from the property.
In March 2018, gardaí conducted a major 12-day search of a 40-acre woodland outside Castlemartyr in east Cork.
However, that yielded nothing of significance in the search for Tina.
Her UK-based sister Teresa also issued a heartfelt plea for information on her beloved sister. “I have one very special message for her – Tina, if you are out there, your family is here. Come to us – we love you and will help you in any way possible. If you need us, we will come to you – whatever it takes,” she said.
“Just let us know that you are fine and you are safe.”
Teresa urged anyone with information, no matter how trivial it might seem, to contact the authorities in Ireland or the UK.
“Please let the police know – take us out of our misery and let us know where she is,” she said. “She is all the time (on our mind) – always and always will be. I do a lot of searching, with papers and stuff, in the hope that she reads them. I do papers in Dublin and Cork, on her anniversary.
“It gets very, very hard for me and my family. It is the ‘not knowing where she is’ more than anything.”
