The brother of a murdered Mayo woman says finally finding her body after 21 years would be '100 times better' than winning the lottery.
Patrick Collins says they just want to give his sister Sandra a proper burial.
There are 876 long-term missing people on the island of Ireland.
Sandra Collins is one of those - last seen 21 years ago this coming Saturday.
The 28-year-old lived in Killala, Co Mayo, with her aunt.
She went alone to a takeaway in the village shortly after 11pm on December 4th, 2000.
She was never seen again and gardaí believe she was murdered.
Patrick Collins is Sandra's younger brother, and he remembers his sister as a "fun, kind, vivacious" person - "the big sister that everybody would have wanted".
He said the family "100% believes" Sandra met someone that night - and for whatever reason that person murdered her, panicked, and then buried her body somewhere around Killala.
Patrick said all his family wants now is to find Sandra's body.
He said: "[Finding her remains] would be like winning the €19 million [jackpot], but it would be 100 times better.
"I'd give every single penny of that. If I won it today... I'd hand every penny over to whoever could give her back to me. Whether it was her killer or not... I don't care.
"She was a lovely person and she doesn't deserve to be dumped in a bog, ditch or drain - she deserves a Christian burial."
He said he doesn't want to know what happened or why it happened - he just wants to know where Sandra is so he and his family can say goodbye properly.
Patrick's plea comes as an online event is taking place this morning to mark National Missing Persons Day, with contributions from the Justice Minister and Garda Commissioner.
