The analysis also did not find any female DNA in samples taken from clothes and bodies of the male suspects, hence ruling out the possibility of sexual assault. The incident raised a massive storm and the Samajwadi Party government of Uttar Pradesh was accused of failing to protect women's dignity in the state.
The Centre for DNA Fingerprinting and Diagnostics (CDFD) in Hyderabad which examined 38 exhibits for DNA traces, submitted its report to the CBI last week. The report has been given to an expert medical panel which will now conclude on the nature of the girls' death, the report said.
The two girls were buried in an area near the Ganga but their bodies could not be exhumed after the area was submerged in heavy rain. The accused in the case, including two police constables, have been in custody for almost three months and might have to be freed if the CBI failed to chargesheet them the next week.
The CBI, however, said that while the absence of the DNA ruled out sexual assault or violent physical contact, it did not rule out "casual contact", said the report.
The next hearing in the case is on August 25.
