CBI official, however, tried to give enough explanations about their failure to establish the motive behind the brutal killing of Aarushi and the Talwars' servant Hemraj in 2008.
"The crime scene was dressed up and all fingerprints were found contaminated. All three servants who were suspects have been found to be innocent," stated a CBI official.
The mobile phone of Aarushi, which was recovered from Bulandshahr in Uttar Pradesh after over a year, was also of little help as data in the phone had been deleted.
While CBI managed to find the phone in a distant city, it failed to recover the bed sheet on which Aarushi was lying in a pool of blood.
It also failed to conduct a 'Touch DNA' test as its three forensic experts said that the samples were highly contaminated.
Rejecting CBI's all allegations against Aarushi's parents, Talwars' lawyer claimed, "If a public spirited doctor were to make such a disclosure (someone had called the postmortem doctor to avoid reporting evidence of sexual activity), the most logical time for him to do so would have been during the 55-day detention of Rajesh Talwar in 2008."
"Had such a statement been recorded then, the CBI would not have released Talwar prematurely, stating in the court in writing that there was no evidence against him (Rajesh Talwar)," the lawyer added.
