Sara u Vincenzo PaduanoInvestigators said that the aggressor used a cigarette lighter to burn Sara’s face after he doused her with alcohol. The officer leading the police investigation, Luigi Silipo said that in 25 years on the force, he had never seen such a brutal crime.

The Prosecutor said that Vincenzo is being held under arrest on suspicion of Sara’s premeditated murder. She told journalists that at first he denied killing her but after an eight hour interrogation, he finally confessed.

Silipo said that Vincenzo “could not accept the fact that she had left him when she ended their relationship.” The investigators said that Vincenzo, a security official who had been dating the victim for two years, was following Sara as she was driving her car.

He then forced her to stop her car on the side of the road, before proceeding to kill her. CCTV footage shows the entire incident including the fact that a number of cars passed by them as Sara was screaming for help.

The prosecutor said that if one of those who had driven past had stopped to help her, she would still be alive.
