Emanuele Ragnedda's car was tested with luminol, the chemical compound used in scientific investigations to detect traces of blood.
In the judicial warehouse in Olbia, where the vehicle of the confessed murderer of Cinzia Pinna was taken, there is also the Lancia belonging to Luca Franciosi, the 26-year-old gardener from Lombardy who, according to investigators, played a supporting role in Ragnedda in the days following the crime.
According to what has been learned, objects considered important to the investigation were seized from the entrepreneur's vehicle.
Investigations have also been initiated on Ragnedda's boat, which is docked in the port of Cannigione. A further inspection will take place in Conca Entosa on Monday.
