“I saw all the cop cars coming and I heard a gunshot and then I went and saw the body,” said witness Paul Neill.

As police approached the fatally injured person they saw what looked like a grenade and called the bomb squad, which came to the scene and checked out the bus.

No police or other passengers on the bus were injured during the shooting. It was determined that the grenade was inoperative, more of a novelty item.
