The family and friends of Esra Uyrun are returning to Ireland to mark the two year anniversary since she went missing.
The 38-year-old mother of one was last seen leaving her home in Clondalkin at around 7.15am on the 23rd of February 2011.
Esra is described as 5-feet-3 inches tall of slim build, blonde highlighted hair, green eyes and tanned skin.
When last seen Esra was wearing black leggins, brown boots,a black t-shirt and either a black jumper or a denim jacket.
Ms. Uyrun's close family friend Ilknur MacCormick says the 'not-knowing' is the worst part.
"Everybody thinks of the absolute worst - and because we haven't had any bad news, we've got hope in our hears" she said.
"just the not-knowing is completely destroying" she added.
