Chandigarh, March 25 -- Citing a Brain Electrical Oscillation Signature (BEOS) test report, police on Tuesday informed a local court that Prof BB Goyal of Panjab University, who is in jail and undergoing trial for the murder of his wife Seema Goyal, was directly involved in the crime. The chargesheet also mentioned that the test, conducted by the National Forensic Sciences University, indicated that Prof Goyal recalled assaulting his wife, fabricated the crime scene, disposed of evidence and also showed his anger towards her. The court dismissed the accused's bail plea. A detailed order is awaited, officials said. BEOS, unlike a polygraph, does not rely on physiological stress responses. Instead, it records EEG brainwave patterns while the subject listens to detailed crime-reconstruction narratives. Scientists analyse whether the brain reacts in ways consistent with having experienced the act rather than merely being familiar with details. The probe mentioned that he remembered putting a cloth into his wife's mouth, fabricating the crime scene and even passing stool and not flushing it at the crime scene which was corroborated by the crime scene photograph. The report also stated that he remembered cutting the wire mesh himself, which the police had suspected to have been cut from the inside to show entry by an outsider. He also remembered disposing of evidence, such as his phone, front door key and the tool used to cut the wiremesh. The same test concluded that his daughter Parul had no involvement in the crime. On November 4, 2021 (Diwali morning), 60-year-old Seema Goyal was found dead at the family's official residence on the PU campus, Sector 14. Her hands and legs were tied and the post-mortem examination found 5-7 injury marks....
