Poverty drove a man to kill his wife, who was suffering from cancer, and mother in Madhya Pradesh's Bhind district, about 500 km north of Bhopal, police said.
In a gruesome act, fourty-five-year-old Ramvir Vishwakarma, a labourer and resident of Anchalpura village, on Wednesday forced his wife Sunita into a trunk and set it on fire.
Vishwakarma then attacked his sixty-year-old mother Savitri, who was sleeping with her grandchildren, with a sharp-edged weapon killing her on the spot.
He also attacked his two children. His eight-year-old daughter Janaki suffered injuries and has been hospitalised. Four-year-old Sundar, however, didn't receive much injuries.
Neighbours rushed to the scene after they heard the commotion and informed the police.
Police arrested Vishwakarma and have recovered the remains of a woman from the trunk.
According to the police, landless Vishwakarma lived in a hut just outside the village and made his living by doing menial work.
He was disturbed since his wife fell ill and saw no improvement in her condition. He told the police that his wife was suffering from cancer.
Vishwakarma confessed to the police that he forced his wife to get into the trunk and then set her on fire.
"How could I provide medical aid to her? I was not even able to feed my family. I couldn't bear the sight of my hungry children and then I decided to end the ordeal forever," he told the police.
Vishwakarma also told the police he had no regrets about killing his wife as she had suffered a lot because of her ailment.
