French news channel TF1 has reported that Sakine Cansýz, a co-founder of the PKK (Kurdistan Workers Party), Fidan Doðan, representative of the KNK (Kurdistan National Congress) in Paris and Leyla Þaylemez who were found shot dead in the Kurdistan Information Office on 10 January have been killed by one single weapon. Bullets of two different brands were recovered in the Kurdistan Information Office where the executions were carried out but, according to TF1 only one weapon fired them.

Quoting anonymous police sources and unconfirmed information, TF1 nevertheless said that "the fact that only one weapon was used doesn't mean the killer was one or alone".

The report remarked that the French police were working on three lines of inquiry. The first being a PKK internal feud, which has been put forward immediately after the discovery of the bodies on January 10 by the Turkish government and media: the second line of inquiry investigates the possibility that three women may have been killed by an extreme right-wing organization. The third is a crime attack, which has however been ruled out by authorities, according to the police source.

“According to initial conclusions, the three women were executed in cold blood”, says the source and describes the killings of the victims, two of whom were killed with three bullets in the head and one other with four, as a professional job.
