In Chelan County, Washington, three young sisters were found dead following a scheduled visit with their father. Olivia, 5, Evelyn, 8, and Paityn Decker, 9, were reported missing by their mother on May 30, 2025. Their bodies were discovered near a campground several days later, with police confirming asphyxiation as the cause of death. Their father, Travis Decker, is the prime suspect and remains at large. A GoFundMe campaign has raised over $330,000 to support the girls’ grieving mother.

In a separate incident in Albuquerque, New Mexico, authorities responded to a house fire on May 24, where the bodies of three family members were found, all fatally shot. That same morning, a fourth body was discovered nearby—identified as the suspected shooter, who died by suicide. Police believe mental health issues may have contributed to the tragedy, though the investigation is ongoing.

Another case occurred in Buenos Aires, Argentina, where a housekeeper found the bodies of a family of four on May 21. Officials believe the mother, who had a history of psychiatric treatment, fatally stabbed her husband and two sons before taking her own life. A note was left at the scene, and recent social media posts indicated emotional instability in the days before the incident.
