On 10 December 2014, Abu Ein took part in a protest march to plant olive trees outside the Palestinian village of
Turmus Ayya, near
Ramallah. During the march, the group had a confrontation with Israeli soldiers, who had been dispatched to the event. The soldiers fired tear gas and stun grenades at the demonstrators. During the confrontation, Abu Ein exhibited signs of physical distress, first sitting down and holding his chest and later losing consciousness. There is video of Abu Ein engaged in a heated altercation with Israeli soldiers, at one point being grabbed around the neck by one. Video from shortly afterward shows Abu Ein sitting down and holding his chest, before falling unconscious and being treated by an Israeli medic. He is then shown being rapidly carried away by Palestinians on the scene. Roy Sharon, an Israeli journalist who was present, stated that Abu Ein was never struck in the chest with a rifle butt.
Autopsy A joint
autopsy was conducted with Jordanian, Palestinian, and Israeli doctors. While both sides agreed that Abu Ein died from a blockage of the coronary artery due to
hemorrhaging, they disagreed on the underlying cause of death. The Palestinian and Jordanian doctors said wounds to Abu Ein's front teeth and bruises on the tongue, neck and windpipe were indicative of violent acts that led to his death. The Israeli pathologist,
Chen Kugel, said that these injuries could have been caused by violence, but that he thought those injuries were "more compatible with the results of resuscitation efforts. ==Personal life==
