A fine of Rs 52,000 was also imposed on him.
District judge Ramshreshtha Yadav passed the order sentencing the accused Sanjay Sharma to life imprisonment and imposed a fine of Rs. 52,000 on him after finding him guilty of abduction of one Govind Kumar alias Guddu (14) for ransom and later killing him out of fear.
Both Sharma and Guddu were neighbours in Bangalitola locality of Rohtas town.
According to the prosecution, Sharma had called on the victim's mobile number to take the latter for computer classes and later abducted him for a ransom of Rs two lakh before taking him to Nawa Nagar in neighbouring Buxar district where he killed the boy on April 14 this year.
The accused later cut his body to pieces in a bid to destroy evidence in the abduction-cum-murder case.
Guddu's brother Vinod Kumar lodged an FIR against Sharma charging him for kidnapping and murder of his brother.
