Susan Kurien, a retired high school teacher, said in a statement here that her husband had reached home and they had supper together on the day he was alleged to have abused the victim in a guest house at distant Kumali.
"I am sure that the allegations against my husband are baseless. Myself and my two daughters firmly believe that the truth prevail in this matter," Susan said.
She said her family was deeply pained that Kurien was being haunted through media (by those levelling charges) after a span of 17 years, raising the same allegations which were found baseless by repeated investigations and judicial scrutiny.
"Those who are fighting for women's right should not forget the fact that Prof Kurien too has a family", she said.
Kurien has all along rejected the charge and opposition's demand for his resignation, saying it was a matter which had already been cleared by the Supreme Court.
The girl from Suryanelli in Idukki district was abducted in January 1996 and transported from place to place across Kerala and sexually exploited by different persons.
The victim had sent a letter to the Supreme Court last week, seeking a review of the apex court's order quashing all charges against Kurien.
