Officers found Muhammad Abu Khdeir’s partially burned corpse shortly after residents of the upscale Arab Beit Hanina neighborhood notified police they had seen a young man being forced into a black vehicle early on Wednesday morning.The killing took place after scores of right-wing protesters marched through part of downtown Jerusalem on Tuesday, rioting and demanding revenge for the June 12 murders of yeshiva students Gil- Ad Shaer, 16, Eyal Yifrah, 19, and Naftali Fraenkel, 16, whose funerals were held earlier that afternoon. Tuesday’s riot resulted in more than 50 arrests.
