The family of missing woman Blathnaid Timothy are renewing their appeal for information.
The 33-year-old Galway woman was last seen on December 14 getting into a taxi on Sir John Rogersons Quay in Dublin.
She had just taken €60 in cash out of an ATM there.
Her sister Aoife Murphy said Blathnaid's family are not sure what her movements were that day.
"Bla's behaviour on the day… was a little out of character for her," Ms Murphy said.
"She left her apartment without her phone, without her handbag, and it appears she didn't have an overnight bag with her.
"That would be unusual for Bla and out of character for her."
