This is Furkan Dogan. He was 18 years old when this picture was taken in November of 2008. He was born in 1991 in New York, but later moved to Turkey with his family. He was studying social sciences in Turkey. He wanted to help people. Today, his body was returned from Israel with four bullet holes in his head and one in his chest, all from close range. No IDF commandos were killed and the ones injured are expected to make a full recovery.
What was he killed for? He volunteered to be on an aid ship challenging the blockade preventing necessary building materials, food, clothing, and medical supplies from getting to Gaza. He wanted to help people. When the IDF boarded the vessel, according to eyewitnesses, they opened fire almost immediately. There's no evidence Furkan was armed when he was executed (I use that word only because he was shot four times in the head and once in the chest by trained military commandos).
