At the same time, Hossein Fazli Harikandi, the Chief Justice of Alborz Province, said that the investigations carried out so far indicate that the reason and motivation for the murder were due to “the existence of personal differences” between the accused and the victims. According to ISNA news agency, Mr. Harikandi said that in addition to the “confession of the accused”, the remains of the murder scene, such as the blood and saliva samples that were previously sent to the laboratory for examination, match the “blood and saliva samples of a number of the accused”.
