Angry over the sale of a goat, a Class 12 student killed his mother in Rajasthan's Jhalawar district and hid the body in a tin box, police said on Friday.
The incident took place at Semliya village in the Sunel police station area of Jhalawar on Thursday evening.
The woman was identified as Nodayanbai Meghwal (40), wife of Balaram.
Station House Officer (SHO) Dinesh Kumar Sharma said the boy attacked his 40-year-old mother with a sharp object, causing deep injuries on the head and body.
The boy later covered the body in a blanket and hid it in a tin box in his house, he added.
When the boy's father reached home from work in the evening, he asked about his wife, following which the boy replied that she has gone to the fields.
The SHO said the houses in neighbourhood of the victim were searched and when the boy's father asked him strictly, he admitted to having killed her.
Police recovered the body from the tin box and shifted it to a mortuary at a local hospital, where it was handed over to family members following a post-mortem, the SHO said.
The boy has been detained, he said, adding that the boy's age is yet to be confirmed.
