Fiancée Siya Goyal and her lover Chetan Chaudhary orchestrated the murder of Ketan Agarwal at Lohagad Fort.
The suspects confessed to the crime after initially attempting to shift blame onto each other during police interrogations.
The couple had attempted to kill the victim on two previous occasions before successfully pushing him off the cliff.
The father of the accused has demanded the harshest possible punishment, even if it applies to his own daughter.
