No, the shooter had ten long guns. If he rotated through the guns, he could easily have done it alone. One gun is cooling while he uses the other nine, etc.
And the numbers of casualties? It was a crowd of 20,000. The shooter didn't "aim" at anything. He just pointed and fired into the crowd. They were standing so close together he couldn't miss.
