Bagalkot (Karnataka), Aug 6 : The police in Karnataka have arrested a woman for getting her adopted son killed with the help of her sons-in-law and lover in Bagalkot district. The deceased youth has been identified as Vasantha Malingappa Kuruballi (24). The police have arrested four persons in connection with the incident -- Kamalavva, her sons-in-law Sindhoora Beeranna and Bheemappa Malali, and the woman's lover and Beeranna's father, Ninganna. According to the police, Kamalavva had lodged an FIR one month ago, alleging that Vasantha had disappeared. The police later found his decomposed body abandoned in a gunny bag. As the police got suspicious about the role of Kamalavva in the murder of her adopted son, they questioned her, which revealed that since the victim questioned her affair with the father of her son-in-law and also asked for his share in the property, she got him killed. In the wee hours of June 19, the accused smashed the victim's chest with a boulder and later smothered him to death. They also damaged his private part. Then they put his body in a gunny bag and threw it into a canal in Belagavi district, the police said. Kamalavva then went to the police station and lodged a missing complaint. /IANS
