The four accused in the infamous Hathras gang rape case will undergo a polygraph and brain mapping test in Gujarat’s Gandhinagar. All the accused are currently lodged in Uttar Pradesh’s Aligarh jail.
The Central Bureau of Investigation (CBI), which is probing the case will bring the accused to Gandhinagar for the tests.
Notably, all the four accused belong to upper caste and they are accused of brutally raping a 19-year-old Dalit girl. The girl eventually succumbed to her injuries in Safdarjung Hospital in New Delhi.
Following the death of the girl, the Yogi Adityanath-led Uttar Pradsh government received flak from the Opposition for the manner in which the case was handled and under pressure had to handover the probe to the CBI.
A month after the Dalit girl was gang-raped by four upper caste men on September 14, a team from CBI started their probe in the case and visited the crime spot.
Polygraph and brain mapping tests
A polygraph test is based on the assumption that physiological responses that are triggered when a person is lying are different from what they would be otherwise.
Instruments like cardio-cuffs or sensitive electrodes are attached to the person, and variables such as blood pressure, pulse, respiration, change in sweat gland activity, blood flow, etc., are measured as questions are put to them.
A numerical value is assigned to each response to conclude whether the person is telling the truth, is deceiving, or is uncertain.
Similarly, brain mapping is a set of neuroscience techniques predicated on the mapping of (biological) quantities or properties onto spatial representations of the (human or non-human) brain resulting in maps.
Hathras gang-rape case history
The 19-year-old woman was attacked on September 14 at Hathras village. She told the cops that she was dragged by her dupatta into the fields where she had been cutting grass.
The family later found her in the fields, naked and bleeding, with injuries on her neck and back.
She suffered multiple fractures, paralysis and a deep gash in her tongue in the assault. The injuries to her neck left her paralysed and struggling to breathe, media reports said.
Her family has alleged that the police did not help them initially and only reacted after public outrage over the incident.
UP police denied that her tongue was cut off and said she bit her tongue when her attackers were trying to strangle her.
News of her death led to protests outside the hospital with the Bhim Army of Chandrashekhar Azad blocking roads for 10-15 minutes and protesters chanting ‘hang the rapists’. There has been an outpouring of grief and anger from politicians, celebrities and others.
The UP police initially registered an attempt to murder case but added rape charges only after the woman’s formal statement. They had denied the family’s allegation of slow response.
