CRUCIAL EVIDENCE THE CBI HAD
Aarushi’s Mobile Phone:
Aarushi’s N72 Nokia phone set, which, according to the agency's then joint director Arun Kumar, had contained clues crucial to the crime, was recovered nearly 15 months after the murders. But the CBI found its
memory — text, audio and visual — wiped out. Delhi police’s crime branch had recovered the mobile phone from Ram Bhool, a Class IV employee at Bulandshaher, who got it from his housemaid sister.
Two Fingerprints: The Noida police had gathered 26 fingerprints from the crime scene but owing to their use of allegedly faulty techniques in doing so "24 of the fingerprints got wasted, while the two that remained did not lead to any of the suspects", according to the CBI. A set of direct evidence was thus lost.
Bloodied Handprint: The CBI had also found a dried, bloodied handprint of one of the killers on the terrace of the building, where Hemraj Banjade's body had been dumped. The CBI had wanted to retrieve the killer's DNA from the handprint and a few clothes of then suspects with the help of a foreign laboratory. The country’s government laboratories did not have the required Low Count Number or touch DNA technique. But the samples were either never sent or the effort did not deliver any result.
Wine Bottle: A wine bottle, Ballantine brand, was recovered from the crime scene and was probably used by the killers. But the CBI could not use the object to derive any useful evidence.
A Shoeprint: The CBI had also gathered a shoeprint — size eight — from the crime scene but it did not provide any leads to the search for the killers.
CRUCIAL CLUES CBI FAILED TO GET
Murder Weapons: Till the end the CBI could not gather crucial or direct evidence that could have led to the killers — the crime weapons that included a knife suspected to be a khukri and a blunt, heavy object. The weapons could have the forensic trace — DNA, fingerprint or blood — of the killers.
Hemraj's Phone: His Tata Indicom phone, which was active for around 18 hours after the murders, could not be recovered. The CBI had suspected it to be a key clue. The phone had been answered by a suspected killer on May 17, when Aarushi's mother dentist Nupur Talwar dialled the number.
