Thai Ghost Captured on Phone Cam

The woman in this clip took a picture on her mobile phone of her daughter and was shocked to see this ghostly image appear on the photo. Her sister, upon seeing the picture, threw the phone away screaming in terror.
The clip explains the history surrounding the area, approximately twenty years ago the area did not have any house built on it and was a wooded area. A local woman was attacked, sexually assaulted and killed there and unbeknown to the current residents their house was later built on the land.
Is this the ghost of the murdered woman who still haunts the area she was murdered in captured on film? Or is it a hoax? The image is reviewed by an photo expert and they try to recreate it, by getting someone to jump whilst the image is taken and also by photoshop. Whilst similar results can be made, the woman that took the photo insists that the image is of a real ghost.
