The Israeli army's military police unit says it is investigating after a Palestinian driver was shot dead at a temporary checkpoint in the occupied West Bank over a week ago.
The military initially described Ahmad Kahla, who was 45, as a terrorist who had tried to carry out an attack.
However, Israeli media said a leaked preliminary report found the father of four was killed unnecessarily.
A video showed a scuffle with soldiers before Mr Kahla was fatally shot.
"How can I explain to you what I feel psychologically or physically?" his son, Qusai, who is 20, told the BBC.
"We were on our way to work together before this happened with the soldiers. Then we were separated, and I only saw my father again when they brought his body to the hospital."
Witnesses said a line of traffic had formed as Israeli forces subjected them to lengthy vehicle checks to enter or leave the village of Silwad, north of Ramallah.
