‘Costly’ reason not to use DNA

Hindustan Times
A major reason behind CBI’s decision not use an advanced DNA profiling technique — the Low Copy Number (LCN) or Touch DNA — to examine evidence in the murders of Aarushi Talwar and Hemraj Banjade was allegedly its prohibitive cost. The investigating team from Central Bureau of Investigation (CBI) was required to pay £60,000 — around R42 lakh — to a British forensic laboratory to access its expertise in using the LCN technique and examine a few key samples found at the crime scene, from which regular DNA profiling techniques could not extract much, said an agency source.
