Besides killing his father, the man also stabbed his mother and his brother when they tried to intervene, reported Times of India.
The incident reportedly took place on Monday, Jul 26 in Jyotibaphule Nagar in Uttar Pradesh under Amroha police station limits.
Quoting police, the newspaper reported on Wednesday, Jul 28 that Rishipal had reservation over the manner in which his father behaved with his wife.
The situation went out of control when the father, Mukhram, offered mangoes to Rishipal's wife. Enraged by this act, which added to his suspicion that his father was trying to establish sexual relationship with his wife, heavily drunk Rishipal stabbed his father.
He later stabbed his 48-year-old mother Gyanwati and his younger brother.
After killing them, Rishipal yet again stabbed their bodies leaving them in a pool of blood.
The only witness to his gruesome crime is Deepak, Rishipal's 12-year-old son. The boy has narrated the whole incident to the police and has informed them that his father left the house with his mother after the incident.
The police have launched a hunt for Rishipal.
