AGRA: A 19-year-old woman from Aligarh was allegedly killed and beheaded by her father, stepmother, and step-grandfather in Hathras for what police describe as an “honour killing” on suspicion of “disgracing” the family. The three accused were arrested on Wednesday.Hathras SP Chiranjeev Natha Singh said, “On Aug 10, residents of Bahradoi village in Sadabad police limits discovered a sack containing a headless body in a canal. The head was recovered shortly afterwards.” Initial identification was not possible, prompting police to form five teams to track the victim’s identity.Photographs of the victim’s clothing were circulated on social media and via community policing networks. A breakthrough came when a woman recognised the stitching on the lower garment as her own work for a missing girl from Adhauna village in Aligarh’s Akrabad area. The victim was identified as Tamanna, daughter of Hasrat Ali (40).Police said Ali married Firdos in 2005 and had two daughters – Tamanna and Nisha (16). Dissatisfied with having only daughters, he separated from Firdos six years ago but kept the girls with him. He later married Rani (38), daughter of Rajjo Pehalwan (60) of Hathras. Investigations revealed that in July, Tamanna had left home with a man, a resident of the same village, but returned two days later. This angered Ali and Rani, who scolded and beat her. On Aug 8, she left again but was intercepted by Ali and Rani near Panaithi bridge. Believing she was “defaming” the family, Ali allegedly discussed the matter with his father-in-law, Rajjo, who advised “dealing with it” immediately. That night, the couple took Tamanna to Rajjo’s house in Alhaipur on a motorcycle. There, the three allegedly laced her food with intoxicants, strangled her when she became unconscious, and took her to the canal. Police say Ali then severed her head and inflicted multiple injuries on the body to hinder identification, while the others held her down. Her clothes were also deliberately disturbed to mislead investigators.
