A bloody handprint, clothes of two murder victims and an empty wine bottle: These are the pieces of evidence, which are suspected to contain the DNA print of the killer/s. These items were recovered from the crime scene by the Central Bureau of Investigation(CBI) and now expected to lead to the cracking of the Aarushi Talwar-Hemraj Banjade murder case of May 2008.
The CBI has now shortlisted a US-based private forensic laboratory, specialising in the Low Count Number method, also called Touch DNA method, which has the ability to extract DNA from an object even if it is so much as touched by a person.
Hindustan Times had, on May 23, reported the fact that CBI Director Ashwani Kumar decided to take help of the technique, not available in India, to crack the case.
Kumar had told HT: “The LCN technique can help us get the suspect’s DNA print. The problem is it is not available with our forensic laboratory anywhere in India. We have visited the websites of the foreign laboratories that have this technique.”
The use of the unique forensic method has become crucial especially in the light of the fact that the 26 fingerprints gathered from the crime scene by the Noida police, from who the CBI took over the case a fortnight after Aarushi and Hemraj were killed on May 16, 2008, got destroyed due to allegedly faulty procedures adopted by the police. Besides, Aarushi’s vaginal swab, possibly a key forensic evidence, was switched at Noida district hospital before it was sent to Hyderabad’s Centre for DNA Fingerprinting and Diagnostics. Two doctors and their former supervisor at Noida district hospital have been interrogated several times on suspicions they allegedly aided destruction of evidence.
The CBI has cut and preserved a section of the wall on the terrace of Aarushi’s flat on which the killer had left a bloody handprint. The killer after tripping on some water pipes had tried to break his fall and had left a bloodied handprint on the wall.
