The murder of a young Sicilian woman by a stalker in broad daylight has sent shockwaves across Italy, where 11 women have been killed since the start of the year.
University student Sara Campanella, 22, was killed by an acquaintance on Monday afternoon in the Sicilian city of Messina.
Witnesses told media that they saw a man - later identified by prosecutors as 27-year-old Stefano Argentino - walk up to Ms Campanella and stab her on the street. She tried to get away and screamed "Stop it, let me go, stop it," before collapsing, they said.
A passer-by who reportedly heard Ms Campanella's screams tried to chase the attacker, who managed to flee.
