A dogwalker believes he saw a headless and naked torso in a woodland pond two days before the police found body parts in the same area.
The man said he just "shrugged it off" at the time but now thinks he saw more than what is being reported.
Human remains were discovered on New Year's Eve in the water, which is located close to the Princess Alexander Hospital in Harlow, Essex, and a murder investigation has now been launched.
