The investigation into the murder of a 45-year-old Delhi University assistant professor, discovered dead in her Vasundhara Enclave apartment, has intensified. Her estranged husband, who was reportedly in Pune at the time of the incident, joined the police inquiry. The couple had been involved in a divorce dispute for four years, with plans for a mutual separation communicated through their lawyers. Police have established that the murder occurred within a five-and-a-half-hour timeframe on Wednesday, with no signs of forced entry into the apartment, indicating familiarity between the victim and the assailant. Forensic experts found a single set of unidentified fingerprints, and investigators are scrutinizing 13 individuals who entered the society on the day of the murder. Among these, two masked individuals, including a woman, were seen arriving in a cab and changing clothes before leaving. The college where the professor worked expressed condolences, calling her death an “irreparable loss” to the academic community.
