Gurgaon school murder case: A Gurugram court on Monday ruled that the juvenile accused in the sensational murder case of an infant inside the toilet of a school here should be tried as an adult or not. Earlier, Judge Jasbir Singh Kundu had given the CBI one week additional time to file its supplementary chargesheet. The family of the accused had moved the court alleging the Juvenile Justice Board (JJB) had given its approval to try the 16-year-old as an adult even before the completion of the probe by the CBI. The court had earlier this month reserved his judgment for May 21. The court's order is important because if the accused is convicted as a minor, he will face a maximum punishment of one year whereas if tried and convicted as an adult, he could face severe punishment. The JJB had in December last year ruled the accused, a Class12 student, will be tried as an adult in the case. The board had in its order observed the crime committed by 16-year-old was heinous, chilling, horrific and serious in nature. Besides, it said the circumstances show the teenager was mature enough to understand the consequences of his act. According to CBI, the accused had murdered an eight-year-old boy just to defer a unit test and a scheduled parent-teacher meeting. The kid was found with a slit throat on the ground floor washroom on September 8 morning last year. Police had initially arrested a school bus conductor, identified as Ashok Kumar, but he was granted bail after no evidence was found against him. The case was handed over to the CBI on September 22 and the Class 12 student, the prime accused in the case, was taken into custody on November 8.
