In Nepal if they are sentenced for 20 yrs then it is actually 10 yrs. The judiciary system counts as day and night..so 24 hours is 2 days. then looking at their mischiefs and more they will be freed in 5 yrs maximum....I would say this guy killed a innocent girl now myself being in teaching profession, I feel shame due to him and now no parents will seek suggestions to teacher about their career. I guess either 190 yrs in prison or Hang Till death but we dont have one .
