Soldier Ghost Picture

Melissa Vanderheyden sent Angels & Ghosts this ghost picture that could possibly reveal the head and shoulders of a Civil War soldier. Take a look...

"This photo was taken in Stones River Battlefield (slaughter pin area) of Murfreesboro, Tennessee."

We cannot see anything in the photograph that would have cast such a shadow. Is it the ghost of a Civil War soldier?  If you have any kind suggestions, please e-mail Melissa at:
