Chandigarh, Feb. 7 -- A local court has convicted a man for killing two sisters in their rented accommodation in Sector 22 in 2019. The convict, Kuldeep Singh, son of a retired police inspector, sentenced on Monday. Kuldeep, who was 30 when the crime was committed, was in a relationship with Manpreet Kaur, 26, the elder of the two sisters. He forced his entry into their one-room accommodation on the second floor of a house in Sector 22 early on August 15, which was Raksha Bandhan that year. According to the police probe, he wanted to check her WhatsApp account as he suspected that she had been in a relationship with another man. They had an argument before he slit Manpreet's throat with a pair of scissors lying there. Before that, he even tried to strangulate her with a dupatta. The younger sister, Rajwant Kaur, 24, raised the alarm but she too was stabbed repeatedly. She was also strangulated with the same dupatta. The sisters belonged to Abohar town of Fazilka district in Punjab and worked in a factory at Zirakpur.
