Plant clues could help find decomposing bodies, scientists say

Researchers looking at whether human remains cause changes that could be detected by drones

They can't shout whodunnit" but plants could offer vital clues when it comes to finding clandestine graves, researchers say.

Forensic experts in the US have begun experiments at a body farm - a facility where decay processes can be studied - to explore whether decomposing human remains leave their mark on surrounding vegetation, for example by affecting the colour of the leaves.
