All that the CBI needs to solve the two-year-old Arushi Talwar-Hemraj Banjade murder case is the killer’s DNA print. This can be retrieved from a bloody handprint the killer left at the crime scene.
However, the CBI hasn’t been able to get the DNA print. Because the method used to extract the DNA from such a sample, the Low Count Number (LCN) method, is not available in India.
CBI Director Ashwani Kumar has confirmed to Hindustan Times that the technique which can retrieve DNA from an object even if it is so much as touched by a person, is not available with the CBI. Kumar said, “The LCN technique can help us get the suspect’s DNA print. The problem is it is not available with our forensic laboratory or elsewhere in India.”
Kumar said, “We have visited the websites of the foreign laboratories that have this technique but we can rely only on our forensic laboratories.”
The LCN technique, sources say, is available with a select group of private laboratories abroad; the list includes the UK-based Medical Genomics Limited, whose website the CBI had visited. “The technique,” said a source, “has helped solve dead-end cases in UK.”
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.
Aarushi and Hemraj were killed, their heads bludgeoned, and neck sliced, on May 16, 2008; while Aarushi was killed in her room, Hemraj was murdered on the terrace of the flat and his body hidden inside an empty cooler.
The handprint is so far the sole solid evidence that the currently clueless agency has to the killers’ identity. “As of now, for us, there are three sets of suspects: Aarushi’s parents (dentists Rajesh and Nupur), the group of three comprising Krishna Thadarai (medical assistant) and domestic helps Raj Kumar and Vijay (Mandal), and a third person who could be an outsider,” Kumar said.
He added, “We have insufficient evidence against Krishna, Raj Kumar and Vijay. We didn’t get any thing against the Talwars in their narco test.”
