#Wikidata & #Amnesty - Razan Zaitouneh disappeared

Razan Zaitouneh is a journalist who disappeared from her home in Douma, Syria with three other people on December 2013. Razan was very well known as a journalist documenting human rights in Syria. Razam disappeared together with Samira Khalil, Wael Hamada, and Nazem Hammadi.

Mrs Zaitouneh received several awards for her work. I was adding one of them to someone else and it is how I learned about her. It is reasonable to expect her to be dead but, how do we document the disappeared. We do not have a convenient date of death, we do not know where she died. We only know that she disappeared.. How do we register this in Wikidata?
Thanks,
