The investigative agency Central Bureau of Investigation (CBI) faced criticism when BK Mahapatra, an expert in Central Forensic Science Laboratory (CFSL), on Monday, Aug 27 stated that he forgot about their proceedings of collecting samples from the murder spot on Jun 1, 2008.
Mahapatra along with twelve other scientists visited the Talwars' residence in Noida and had lifted samples based on which the CBI has established the case and accused Mr and Mrs Talwar as the only suspects in the case.
According to the defence lawyer, Mr Mahapatra, a crucial witness from the CBI's side, was confused and could not remember whether a pillow found in Aarushi's room was of her own or of somebody else.
In an another setback for the CBI, Mr Mahapatra said that he did not follow the rules laid down by the National Accreditation Board of Testing and Calibration Laboratories (NABL) while taking pictures of the articles collected for performing tests. According to the witness, the CFSL followed its own manual.
The defence lawyer in the court claimed that the investigating agency could not establish its case scientifically. The court proceedings has been adjourned till Tuesday.
Nupur Talwar has been lodged in Dasna jail in Ghaziabad since Apr 30, 2012 in connection with the Aarushi-Hemraj double murder case and has been fighting in the Supreme Court to get bail while her husband is on bail.
14-year-old Aarushi was found dead in their residence in Noida on May 16, 2008. Their domestic help Hemraj's body was found the next day. The CBI in its closure report stated that Aarushi's parents are the only suspects in the case.
