Spath, you seem to have latched onto the phrase 'tipped off' and made it suspicious.
From an earlier rather stilted interpreter.
//We (the searchers) were progressing through the area, mist were looking to the right. A member of the team looked to the left and saw something lay across and alerted the others.
We approached and were 10/12 feet away, saw the body and knew not to touch, we also knew we were not to take photographs.//
The above is my paraphrasing as I can't find the piece just now but is what she said.
