The murder and dismembering of this 18-year-old girl and arrest of a failed asylum seeker has convulsed the Italian elections

Flowers are still arriving at the roadside for Pamela Mastropietro. It is just over two weeks since this troubled blonde 18-year-old went missing here, only to resurface in a pair of suitcases left in a ditch.

No sooner was an illegal immigrant arrested for her killing than a local neo-fascist took it upon himself to drive around town in broad daylight shooting anyone who looked vaguely foreign.

Six African migrants were injured — though no one has left any flowers for them.

Several arrests and the arrival of one of the country’s top police officers here have done little to calm the mood.
