A 32-year-old man, Alexandre Kamienski, has been arrested in Cuiabá after allegedly murdering his uncle and assaulting his grandmother. The incident occurred on Monday when the police were called to the Jardim Maluf neighborhood at around 2:30 AM. The suspect reportedly confessed that the violence was provoked by the discovery of compromising photographs involving his uncle and his girlfriend.

When officers arrived at the scene, they found the uncle deceased in one of the bedrooms, with a significant amount of blood present. This tragic situation escalated as the suspect's 71-year-old grandmother intervened, resulting in her being assaulted and sustaining a fracture to her arm while trying to protect her son. Emergency medical services attended to the scene, confirming the death of the uncle and transporting the grandmother to a health facility for treatment.

The police apprehended the suspect at the crime scene, where he was found still present after the violent altercation. This case underscores issues related to familial violence and the extreme consequences of emotional disturbances, raising public concern over the safety and dynamics within families in Brazil, particularly in light of such violent acts prompted by jealousy and personal grievances.
