Forensic expert BK Mahapatra revealed before court the presence of blood and female DNA on clothes of Aarushi Talwar’s parents the night the twin murders took place.
He said the clothes of both Rajesh and Nupur Talwar had presence of “faint blood stains,” which meant that either the blood stain was very small or had been washed away.
The Central Bureau of Investigation (CBI) also produced Aarushi’s bedsheet on which CBI had found a ‘circular mark of wetness’ below the pelvic area of her body.
The bedsheet had been sent for forensic examination to confirm the presence of urine, DNA or any biological fluid.
Mahapatra said the circular mark had no trace of urine, DNA or any biological fluid and could be due to any other liquid. His statement supports CBI’s theory of “dressing up of the scene of crime” in which the agency had stated that there was “evidence of post-mortem cleaning of Aarushi’s private parts.”
Mahapatra also stated that four slides containing vaginal swabs had “a white faint stain,” but no semen was found. Also, no conclusive female DNA was generated as the biological material was from more than one female source. This suggested that the slides were either contaminated or tampered with.
Mahapatra also confirmed that the khukhri seized from the servant-quarters of previous suspect Krishna could not generate any DNA profile. The CBI has already clarified that “human blood could not be detected” from Krishna’s Khukhri.
