OK - please define "signature" for me as it relates to homicides.

In the Butts case, three pubic hairs were found, one having a crab egg. One hair was on her toe, two with the comforter. I don't think it is known which hair, the one on her or one of the two with her, had the crab egg on it.

Until I know what a homicide signature is, I'm saying three pubic hairs are pretty good signatures! :-)
