Additional Sessions Judge Rakesh Kumar awarded them the jail term for murdering the man by hitting him with a cricket bat on his head, neck and private parts.
The court said the very act of the duo of removing and destroying clothes which the victim was wearing at the time of the incident and replacing them with new ones strengthens the prosecution case that it was they who had killed the man and destroyed the evidence thereafter.
The court rejected the contention of the accused that the kids can be easily influenced and tutored due to time gap between the incident and recording of their statements.
"I find the same not convincing in the present set of circumstances where accused...Is mother of these witnesses and it cannot be expected from them that they would implicate their mother falsely or without any reason.
According to the prosecution, the kids had told the police that their parents used to frequently fight with each other as their mother used to call her friend to their house.
On April 9, 2011, the woman called her friend to her house on the pretext of bringing her a match box over which the couple fought. The accused then caught hold of the victim and his wife beat him with the cricket bat after which the man fell down and became unconscious.
