In July 2026 Turkish authorities handled separate violent crimes involving suspects named Ataş. Early in the month, four people were arrested after the killing of Abdulkadir Ataş in Kuşadaşi, though details were limited. Later in the month, police apprehended Osman Ataş for a triple homicide in Adana, where he shot his girlfriend and two by‑standers, reportedly motivated by jealousy.
