deceased. It is an admitted case of prosecution that deceased Rekha @ Mamta died in her in-laws house. The fact that Rekha @ Mamta had fallen from the stairs at her in-laws residence did not come up in statement of any witness, recorded under Section 161 of Cr.P.C. It is prima-facie, only an assumption or imagination of Investigating Officer that Rekha @ Mamta slipped from the staircase which resulted into injury to her. It prima-facie, appears that Investigating Officer has brought this fact on file, beyond the record in order to weaken the case of complainant/prosecution and to facilitate the accused to get a basis for defence. The I.O. was not the eye-witness of the incident, who could have narrate such observation of falling of Rekha from the stairs in site plan. In view of the PMR and medical report, prima-facie it is a case of unnatural death.
