One person was stopped by the police in Turin during the investigation into the murder committed on Halloween evening.
The case is that of Massimo Melis, an operator of the Green Cross killed with a gunshot to the head in his car parked in Via Gottardo, on the outskirts of the city, on October 31st.
Melis was killed in his car parked in via Gottardo, in the Barriera area of Milan, immediately after having accompanied a friend home.
At first the investigations had not ruled out the hypothesis that the attacker was an acquaintance of the woman.
However, alternative hypotheses have never been neglected: from the testimonies collected by the investigators it appears that he had had problems with the tenants of an apartment he owned.
