A 55-year-old man has been detained on suspicion of killing his mother and her husband, who were found decapitated at their home in Mirandola, in the province of Modena, in Emilia-Romagna, northern Italy. The victims were Vincenza Giannini, 74, originally from the province of Foggia in southern Italy, and Pier Ferdinando Casari, 83, who was born in the Modena area. Their bodies were discovered late on Thursday afternoon. The suspect, Daniele Tavoni, underwent extensive investigative procedures as law enforcement officers remained near the house on Via Imperiale throughout the night. Evidence gathered by investigators led to his detention between Thursday night and Friday morning. Investigators are working to reconstruct the circumstances of the double murder and establish a possible motive. According to preliminary reports, the 55-year-old and the couple had previously been involved in disputes over financial matters.
