The version given by the families of the two Badaun rape victims about the chain of events has not convinced CBI as it came to light that they withheld the elder sister's slippers, which she apparently wore at the time of the crime, from the probe team.
CBI sources said they have sent the soiled slippers for forensic analysis hoping they may provide some clue to the crime.
They said a variety of material having evidenciary value like hair, nail, blood, soil etc can be collected from personal belongings of the victim which can help in piecing together the missing clue to solve the crime.
Highly placed sources said the family members of the victim, who kept feigning ignorance about the slippers, provided the footwears to CBI only after intense grilling.
The sources said although they are not doubting the intentions of the family members they are not cooperating enough in the investigations.
Earlier also, the mobile phone of the victim was not provided to CBI officers. When the agency had put pressure, the family provided the phone in broken condition.
During the examination of the family members, including the fathers of the victims, CBI found a series of loopholes making the investigation difficult.
The two cousins, aged 14 and 15, went missing from their house on the night of May 27 and their bodies were found hanging from a tree in the village in Ushait area the next day. The incident had sparked a nationwide outrage.
CBI has subjected four persons--fathers of the two victims, a relative of the family and an eye witness--through lie-detector test as the agency is not convinced with the statements given by them.
The agency is awaiting the results of the polygraph test after which a decision on further tests will be taken.
