The Mumbai crime branch are awaiting reports of various scientific tests that have been conducted on the four adult accused and the juvenile to bolster evidence against them in the gangrape of a 22-year old photojournalist at Shakti Mill in Mahalaxmi on August 22.
While the DNA samples found on the survivor matched those of the accused, the police are now awaiting DNA reports of the clothes the accused were wearing during the crime, which were recovered during raids at their homes.
Crime branch officials said the reports of the voice layer analysis tests, which were conducted by experts from the Gujarat forensic laboratory, would also be used for the first time in any case in the city, and will be part of the charge sheet. Sources said the results were expected soon, along with the reports of the forensic experts from the Central Bureau of Investigations (CBI).
The crime branch is also conducting blood tests on all the accused, and a bone ossification test on one of the accused Mohammed Kasim Hafiz Sheikh alias Bangali, whose family has also claimed he is a minor.
The statement of a witness, who had seen three of the accused leave for Shakti Mill just before the incident has been recorded as well. The three allegedly got call from Salim Ansari, the key accused in the case and call records on his phone showed that the call was made by Bangali.
The crime branch has also recorded the statement of the survivor and that of her colleague, who was overpowered and tied up in the compound when the incident took place. The crime branch is still searching for a sweeper who supposedly passed by the spot during the attack.
