The family of missing Tyrone woman Charlotte Murray have renewed their appeal for information on the fifth year anniversary of her disappearance.
Charlotte Murray, 34, was reported missing from Moy in May 2013 but had not been in contact with family or friends since the previous autumn, PSNI revealed.
Ms Murray, originally from Omagh, had been living in Moy. Appeals for information as to her whereabouts were made by police and her family in the summer of 2013.
Her family and Police have re-appealed for information to end their family's "heartbreak."
In a video plea to find their sister, Charlotte's two sisters and brother spoke of their anguish of not knowing of their sister's whereabouts.
Her twin sister Denise said: "Our sister Charlotte's disappearance is one of the most horrific experiences we have ever faced in our lives.
"It's heartbreaking to know Charlotte out there somewhere and we can't do anything to help her.
"Since our sister went missing in 2012 our emotions have been all over the place. Hope has been our friend in this nightmare and we cling onto it."
"Guilty is one emotion we all feel, we feel guilty for going on with our every day lives as Charlotte will never get the opportunity to carry on with hers."
Her family added: "Charlotte has missed so many family events and celebrations that constantly reminds us that Charlotte is not here with us.
"We will be spending our 6th Christmas without her this year. Loss is an emotion we suffer as we wake up each day and go to sleep each night."
Twin Denise said her family "are in mourning but have no special place to go to remember Charlotte".
"We also feel each other's pain. Our poor mum is inconsolable and there is nothing we can say or do to help ease our pain. She gave Charlotte life and not knowing what has happened to her is heartbreaking for our mum," she said.
"We suffer every day as we try to come to terms with the thought that we might never get to see Charlotte again. She was such a positive and outgoing person, the life and soul of the party and such great fun to be around."
"Someone has taken her life and they know what they have done," Charlotte's family added, "We are appealing for that person to come forward. Please find the decency to tell us where she is. We just want to say goodbye."
Police are working on the belief that Charlotte has been murdered.
Detective Chief Inspector Eamon Corrigan appealed for anyone who may have any information that will help with the investigation to come forward.
He said: "We have made significant progress over the past 12 months and I would like to make a specific appeal for information about Charlotte's engagement ring and her mobile phone.
"Both these items are of great importance to my investigation. The ring has a gold band with diamonds with a hexagon shape in the centre.
"Charlotte's mobile phone was a Samsung Galaxy YS5360.
"If you have came into possession of either of these items since Charlotte went missing please contact us."
The Detective Chief Inspector added: "Charlotte's family miss her and they deserve and need to know what happened to her.
If you have any information no matter how small, please contact Detectives in Gough on 101 extension 34233."
