MEERUT: Decked up in bridal finery, she observed day-long fast on ‘Karwa Chauth’ for long and healthy life of her husband. Like other women of North, she wore a smile on her face and waited for the moon to turn up to eat food with him. But, as the moon drifted further and night progressed, Kavita Saini’s forced smile gradually wore off, and she looked at her husband’s face one last time before striking a deadly blow on his head to “avenge her daughter’s murder , and years of assaults and humiliation”.45-year-old Kavita, with the help of her son and domestic help, allegedly overpowered and killed her husband Sunderpal Saini on Saturday night. She chose ‘Karwa Chauth’ to carry out the murder to evade suspicion, police said, as they cracked the case within two days.Kavita Saini, her son Kuldeep and servant Shaadri were arrested on Monday from Daurala area of Meerut.During questioning, Kavita told police that her husband had strangulated their 14-year-old daughter to death over a minor tiff, and later showed it as a case of suicide. "No police complaint was filed due to his fear,” she said.She alleged that her husband used to beat and humiliate her regularly. “After years of suffering, I chose to take this step,” she told police.Police produced all the three accused during a press conference.Superintendent of police (SP) Ranvijay Singh said: “The woman has confessed that she was troubled with her husband’s behavior. According to her, he used to thrash her and the boy daily. She also said that about eight years ago, Sunderpal had strangulated their 14-year-old daughter to death. But it remained a family secret . She not only wanted to avenge the murder of her daughter, but she was also worried about her son’s future.”After the murder, Kavita told neighbours that her husband was vomiting blood. However, the neighbours grew suspicious when they saw blood oozing out from Sunderpal’s head and police was called. Sunderpal’s mobile phone and blood-stained clothes were buried in a sugarcane field by the accused.“We have booked Kavita, her son Kuldeep and their domestic help Shaadri under relevant sections of the Indian Penal Code including section 302 (punishment for murder) and section 201 (Causing disappearance of evidence of offence, or giving false information to screen offender).
