The prosecution sought death penalty for Rahul, convicted of 'cold blooded and well planned' murder of two teenaged siblings in December 2011, here on Saturday.
The court deferred pronouncement of quantum of sentence to Monday.
Rahul, 28, was a distant maternal uncle of the victims Gaurang Sahu, 15, and his sister Kavita Sahu, 17, and was convicted on February 11.
Gaurang and his sister Kavita were brutally murdered at their residence in Sector 41 on December 16, 2011.
A resident of Raipur Rani, Rahul killed the two with a sharp-edged knife after Kavita objected to his advances, the police claim.
Arguing on the quantum of sentence, public prosecutor Manu Kakkar said, “It was a gruesome murder in which the convict stabbed the victims a number of times till they died. It was a well planned and cold blooded murder, thus, he does not deserve any clemency."
Guarang was stabbed six times in his chest and also had injuries on his knee and hand, while Kavita was attacked with a knife four times and also suffered injuries on her wrist.
The defence counsel urged the court to take a lenient view considering Rahul's young age. Taking ground that Rahul is a drug addict, the defence urged the court to award him a life term, which would be enough to meet justice.
