Özgecan Aslan (22 October 1995 – 11 February 2015) was a Turkish university student who was murdered while resisting attempted rape on 11 February 2015 on a minibus in Mersin, Turkey. Her burnt body was discovered on 13 February. The murder was committed by minibus driver Ahmet Suphi Altındöken, and his father Necmettin Altındöken and friend Fatih Gökçe were accomplices in covering up the murder. All perpetrators were handed aggravated life sentences without the possibility of parole.The murder caused nationwide outrage and sparked protests across the country on the following days. Thousands of protesters took to the streets in several provinces, with some criticizing the government for its "insufficient response" and alleged normalization of the rape of non-conservative women. The protests were described as the first mass movement for Turkish women. It also provoked calls for reforms to combat violence against women more effectively. The case received great attention on social media and prompted women to share their experiences of harassment, with 16 February being dubbed as "Black Monday" due to protests. The murder was described as a catalyst for women to speak out about their long-withheld suffering, but The Guardian expected also a rift between women who defend silence and patriarchal status quo and those refusing to keep quiet.
