what is misery situation of the parents. actually they are to be killers  of both. but in my opinion once committed the crime so accept and enjoy in the jail. there are no options. one moment act become life long accused. now see the position of them . they are wasting time, money energy and food and tried to proof that we are innocent.if they will accept the crimes so there will be no problems. they will come back soon from the jail and will pass their lives peacefully. and there will be no mental tortures and will be in safety zone. at present they have no option so surrender and accept the  misdeeds and enjoy.
