THE man who prosecuted "lesbian vampire killer" Tracey Wigginton says she remains dangerous, a fear shared by Wigginton's own half-sister and relatives of victim Edward Baldock.

Wigginton, who nearly decapitated the father of five in a frenzied knife attack before drinking his blood, will be paroled in a matter of weeks despite a prison altercation five years ago that returned her to a more secure prison.
