Tragic Kauan Gabriel Chalegre Arruda died when his dad plunged a blade into his chest as he sat on the sofa in his living room in Curitiba, Brazil, on 20th December.

According to local media reports, his 36-year-old father – whose name has not been released by police – accused him of having an affair with his stepmother.

The teenager denied the allegation, but in a heated row, his father pulled a knife and plunged it into his chest.

Badly injured, he tried to flee but was stabbed twice more and died from his wounds at a neighbour’s house before help could arrive.

When police seized the suspect, he still had the knife in his hand.

Neighbours revealed that the family often fought and said it was not the first time the father had accused his son of having an affair with his partner.

The suspect is said to have a long criminal record and was reportedly on drugs at the time of the killing.

Corporal Knoll of the Military Police told local media: “The perpetrator of the crime was carrying the knife used in the crime.

“He was approached by the team and offered no resistance. He was confused, reported that he had used cocaine and had confused ideas.”
