Chandigarh Police on Monday arrested Punjab University professor Dr BB Goyal, 65, for the brutal strangulation murder of his wife Seema Goyal on Diwali morning, November 4, 2021, after advanced forensic brain mapping revealed he could no longer hide from.

The murder inside the couple’s official campus residence had baffled investigators for over four years due to complete absence of physical evidence: no fingerprints, no DNA, no murder weapon, no forced entry, and CCTV showing no outsider. The only person present in the house that night was Professor Goyal himself, who claimed he found his wife unconscious after the door was mysteriously locked from outside.

Suspicion deepened when the victim’s brother approached the Punjab and Haryana High Court, which ordered expedited investigation. With traditional forensics yielding nothing, police turned to neuro-forensic technology in 2025. Brain Electrical Oscillation Signature (BEOS) profiling conducted on Goyal in July showed unmistakable electrical responses when crime-specific details were narrated, scientifically confirming he possessed “experiential knowledge” of strangling his wife and staging the scene.

Supporting evidence included the couple’s daughter Parul passing a polygraph test that indicated her father’s involvement, mesh doors cut from inside, the victim’s phone never leaving campus, and Goyal’s delay in informing police while shifting the body himself. SSP Kanwardeep Kaur confirmed the BEOS result as the decisive factor that finally enabled the arrest after 1,497 days.

Despite remaining the prime suspect, Goyal continued teaching at UBS, even becoming department chairperson months after the murder and secured service extension through court orders. Following Monday’s arrest and three-day police custody for crime reconstruction, Punjab University announced his immediate suspension and stated that services will be terminated upon conviction.
