Attacked by a Ghost

During an investigation into a seemingly malevolent haunting, two investigators entered the house's attic to check out reports of strange sounds by the family.  While in there, one of the investigators screamed out and the other took his terrifying picture of what they claim is the investigator being attacked by the entity.

As you can see, a cord is wrapped around the man's neck and he is being strangled.  The man escaped and exited the attic with the piece of cord still wrapped around his neck.

The family in the house had moved out the night before due to the evil presence and it's hard to imagine this event convinced them to move back in.
