Just look at the page carefully, second paragraph: "At least 10 people or so with their arms tied behind their back being brought to Sam Bockarie."
Go to the next paragraph: "The witness then saw Sam Bockarie shooting them with a pistol in the head. He shot all of the people that were there with their hands tied behind their back." That means he shot 10 of them. Was it 10 or was it five?
