Ali Furkan Yabaneri, a 24-year-old electrical engineering student at Istanbul’s prestigious Koç University, died of an overdose months after his father was jailed as part of the government’s post-coup crackdown.

Local media said Yabaneri committed suicide at his family’s home in the central Anatolian province of Kirsehir on Jan 15. A last-year student at the electrical and electronics engineering department, he killed himself due to his father’s imprisonment, relatives told media.

Hurriyet said the Public Prosecutor’s Office launched an investigation into his “suspicious” death.

Yabaneri was accepted to Koç, a non-profit private university with full scholarship after he was ranked one of the 500 best performing students in the nationwide university entrance exam in 2012.

“The father Mehmet Ali Yabaneri, a chemistry teacher at Kirsehir Science High School who were earlier arrested, was allowed from prison to attend his own father’s funeral 5 months ago. Now he is going to attend his 24-year-old son’s funeral,” Yildirim Kaya, a member of the the opposition Republican Peoples’ Party’s (CHP) local branch in Kirsehir told media on Tuesday. According to media, the father was dismissed from his profession in September 2016 and has been recently sentenced to 8 years and 9 months in prison over ties to the Gulen movement.

The number of people who committed due to post-coup sufferings has passed 50, Kaya added.

“The latest [post-coup] victim who killed himself is one of the smartest children in Kirsehir,” he bemoaned.

Turkish government accuses the Gulen movement of masterminding the July 15, 2016 failed coup while the group denies involvement.
