GUWAHATI, Dec 10 - The Criminal Investigation Department (CID) is in touch with senior forensic experts based outside the State to make a watertight case against the lapses done by the Forensic Science Laboratory (FSL), Guwahati vis-�-vis the Jogdal mass murder case.
Sources told The Assam Tribune that the CID special investigating team (SIT) will soon summon Pushpak Kumar Baruah, the then deputy director of biology division of the FSL, Guwahati, for questioning, as there are inconsistencies in his opinion and report in regard to DNA profiling of the semen found available in the vaginal smear and vaginal swab collected from one of the victims, Sabita Doloi (12).
Sabita, who is suspected to have been raped before being killed, was the daughter of Harakanta Doloi, who along with five other members of his family was killed in cold blood on December 13, 2009 by unidentified assailants.
Investigators believe that Baruah�s professional conduct was in gross violation of the standard operational procedure of the FSL, which amounted to destruction of evidence, besides misleading the investigation.
In response to the request for DNA profiling by then Superintendent of Police (CID), Baruah had intimated in writing that the exhibits sent were not suitable for DNA analysis and found to be too less in quantity for DNA profiling.
Investigators are of the opinion that Sabita was raped before being killed by the unidentified assailants.
�As far as manual of DNA typing is concerned, less than one nanogram is sufficient for initiating DNA profiling. Opinion furnished by expert PK Baruah could never be beyond doubt, which points to mala fide intention to provide relief to the culprits of the case,� the FIR filed by the CID stated.
Baruah in his report also opined that the exhibit Sero 2548 (E) was too small in quantity that it got exhausted completely during the serological analysis, which, according to the investigating agency, cannot be accepted, as the exhibit had to be preserved by the expert for future reference and analysis, should there be any controversy.
�The first investigating officer sub-inspector Abdul Matlib Choudhury, who is currently in judicial custody, did not even seize the apparel of the deceased (Sabita), which is beyond any justification,� sources said.
�It is due to the misconduct of the forensic experts and the two police officers that rape of the minor girl could not be proved beyond doubt,� sources added.
