The pair have now been formally recognized as casino croupier Antonino Calabro, 26, - generally known as Nino - and his fiancée Francesca Di Dio, 20, who're both from Italy. Mr Calabro worked as a table video games dealer at a casino in Stockton and was being visited by Miss Di Dio at the time of the alleged murder. The couple had been engaged for three years and Mr Calabro asked Miss Di Dio to spend time with him over the Christmas holidays, in response to Italian newspaper La Stampa. Cleveland Police have since released photographs of Mr Calabro and Miss Di Dio and their households are both being supported by specially skilled officers. It's clearly one thing going on in the flats, the police have been going in and out. Crime scene investigators could be seen carrying proof luggage and working in the constructing on Wednesday afternoon, and a police cordon was erected blocking entry to the property. Pictures showed the area across the property cordoned off, with two police vans at the scene and forensic officers re-entering the property.
