Botanist tells how nettles helped solve Soham murders

I remember that the detectives working on the Soham case in 2002 sent a voicemail to one of the missing girl's phones and then appealed on TV for their abductor to listen to the message. At the time this seemed like quite a strange thing for the detectives to do (people were a lot less savvy about phone evidence back then). It got a lot of coverage in the press.

In retrospect I wonder if it was a stingray-type gambit, whereby if the abductor turned the phone on they would be able to trace exactly where they were. I don't think it got mentioned in court so perhaps it was unofficial/inadmissable

The Desert Island Discs interview from which this article is derived is available here fwiw:

She was also interviewed on the excellent The Life Scientific (dive into the hundreds of episodes)

It's cool, but after reading up on the murders, it seems like they had already zeroed in on the suspect, and knowing the bodies were placed where they were when they were was not particularly impactful in the investigation - at the very least, the gamekeeper who discovered the bodies noticed a smell a few days before the discovery, and the remains were partially skeletonized, indicating that they had been there for a while.
