I don't think it is a signature when a pubic hair is left behind - - I don't think the killer plans that or wants it.

To me, a signature might be ..... well, remember John Brewer Eustace? He was questioned in the Ramsey case and when asked to donate a pubic hair he laughed - - he hadnone. HE was a pedophile who wantedto make sure he left as little evidence behind as possible so he routinely shaved every bit of his body. To me that is a signatiure.
