This is Nadim Nawara who "was killed by a bullet to his chest" or more precisely "to heart":
Strange I cant see any blood or chest heart wound, although M16 bullet causes huge wounds. On video he was killed on 13:45, yet you dont see any blood stains on 14:58 footage either.
I could not find any pic of Mahmoud Odeh Abu Thahir (one source says he was killed on back, other says he was killed to the lower abdomen). Although
3 photographers running immediately (who dont seem scarred or worried).
Also its strange that both were killed exactly on same spot right in the center of CCTV camera field of view.
Very possible that these CCTV killings were staged while real guys were killed in other place.
