YUMA--This screen grab shows a man, who appears to be holding a shotgun.
"As far as right now, we have the reports of the shots fired. We saw nothing on scene that would lead us to believe that there were actually shots," said Alfonso Zavala with YCSO on Monday.
When deputies arrived to the scene, the men who stabbed the others were already gone.
"We have no reason to believe this was gang related," Zavala added.
However, several people who said they witnessed the fight said they saw the large group of men throwing up gang signs.
No arrests have been made in connection with this case.
