The Mumbai police will conduct psychological tests on the five accused of raping a photojournalist to ascertain if they had committed crimes, and what sort of crimes. The gang has admitted to involvement in three cases of which two were probably gang rape and one of molestation in the past six months. The police have recovered undergarments and clothes of two of the five accused. The five were taken to JJ Hospital for DNA tests.
“A central forensic science laboratory (FSL) expert team on Tuesday visited the scene of crime and collected samples.
These samples will be analysed to confirm the presence of the accused at that particular spot at the time of the crime.
We also sent the suspects to JJ Hospital to get their DNA samples. These will be sent to FSL to match them with vaginal swab of the victim and samples collected from the crime scene,” said a police officer involved in the investigation.
According to sources, two forensic experts from Gujarat FSL will conduct psychological tests on the accused. “They have technology known as Voice Layered Analysis (VLA) with which voice samples of the accused will be analysed.
They will be questioned about crimes committed in the past.
The idea is to measure the deviation of voice which provides an entry point for further probe,” said a police officer. “With these tests we want to confirm whether what they are telling us is correct. Second, the gang has admitted to being involved in three such crimes during the last six months, of which two were probably gang rape and a molestation.
Hence it would be important to know what they had done in the past and whether the earlier offences were committed at the same spot or somewhere else,” the officer said. “It is more like a tool of investigation rather than something which is admissible in a court of law. We are doing such profiling for the first time,” said joint commissioner of police, crime, Himanshu Roy.
