Springfield, MA — Authorities have released new details in a devastating incident that left three people dead inside a State Street home late last month, a tragedy that has shaken families and stunned the Springfield community.
Hampden District Attorney Anthony D. Gulluni on Monday confirmed the identities of the victims and outlined the early findings of an ongoing homicide investigation. The discovery was made on Tuesday, November 25, 2025, after Springfield police responded to a call reporting a possible stabbing at a residence in the 1400 block of State Street.
Officers arrived shortly before 10 a.m. and, upon entering the home, encountered a grim scene: three adults—two men and one woman—dead inside. The severity of the injuries immediately triggered a major investigative response involving homicide detectives and prosecutors.
Investigators have identified the two victims as 67-year-old Khamkieo Chingvacha of Springfield and 47-year-old Sachivanh Phomphanh of West Hartford, Connecticut. According to authorities, both individuals are believed to have been fatally stabbed during the attack.
The third person found inside the home, 43-year-old Kung Kedjumnong of West Hartford, has been identified as the individual responsible for the killings before taking his own life. Evidence collected at the scene, officials said, strongly supports this conclusion, though a full investigative review remains in progress.
Springfield Police Department’s Homicide Unit, led by Captain Trent Duda, is working closely with the Hampden District Attorney’s Murder Unit to piece together the sequence of events and determine what may have led to the violent confrontation. Authorities have not commented on possible motives or the relationships between the individuals, emphasizing that investigators must complete a thorough analysis before drawing final conclusions.
Officials stressed that there is no ongoing threat to the public, aiming to reassure residents rattled by the disturbing incident.
Neighbors described the hours-long police presence as “frightening” and “heartbreaking,” sharing their disbelief that such violence unfolded inside an otherwise quiet residential area. Many continue to struggle with the tragedy, as investigators work to understand what happened behind closed doors that morning.
The community awaits further updates as the investigation continues.
