image doesn't relate to article

Why is there a picture of a Sig Sauer pistol next to this article? The article mentions a strong arm robbery by four men against one man. Did the four robbers use a Sig Sauer in the robbery? Would four men need a pistol to rob one man?

If you actually read the article, they used some sort of gun, yes. Allegedly. Given it's just a file photo of a gun, I'm not sure the caption needed to name the type. But still.
