Prom Ghost Photo

Riki sent us some more ghost photos this month. Check out her old ghost photo. This picture has a white streak across the middle. Is it a moving orb or vapor trail? Did the camera strap get in the way? Riki says it is not the camera strap, as this was taken with a video recorder:
"Here is a pic of my oldest daughter right before her prom. What is that in the picture? By the way, she hated this house, as she often saw things that scared her."
"I am sure this is not a camera strap, because it was taken with a video camera. The lens was a good 8 inches in front of, and 6 inches above the camera strap which was located on the very bottom of the camera. Someone would have had to pull it up and hold it up in front of the camera purposely."
