Tokom istrage su u advokatovom kompjuteru nađene poruke elektronske pošte koje povezuju pucnjavu s PKK, kažu policijski izvori i dodaju da postoje dokazi i o direktnom kontaktu između Mahmutoglua i Ucmaka, kao i plan bolnice Maslak Acıbadem, gdje se Tatlises liječi od rane od metka u glavu.
E-mails that connect the shooting to the PKK were found on the lawyer's computer during the investigation, police sources say, adding that there is also evidence of direct contact between Mahmutoglu and Ucmak, as well as a blueprint of the Maslak Acıbadem Hospital, where Tatlises is receiving treatment for a gunshot wound to the head.
