Detectives investigating the murder of a dogwalker have released chilling CCTV of their prime suspect dancing as he walks away from the scene.
Marilena Negri, 67, died in the Villa Litta park in Milan, having been stabbed.
It was around 7am on November 23, when she was knifed in the neck by her attack as she walked her pet Beagle named Liz.
Police are working on the assumption that the attack was a robbery gone wrong.
Mrs Negri was found alive by a passerby, with an empty handbag and her dog tied to a lamppost nearby.
