Definitely B.S. The spin the media is doing with it is ridiculous.
As an example, here's one headline: "Killer Nanny's Chilling Words to About Why She 'Stabbed Children to Death After Massive Fight With Their Mother"
Then the first sentence in the article, is that she "did not confess to the murders when questioned by police, but told them: 'Marina (the mom) knows what happened.'
Gotta poison that jurry pool, , drum up a clever marketing term "NANNY KILLER" and plaster it everywhere, get a quick conviction.
