Hawaii island police are investigating the death of a 4-year-old girl that resulted from a stabbing Wednesday at a Hawaiian Beaches residence.

Puna patrol officers responded to a call at 11:44 a.m. about the girl with an injury to her neck.

At the time of the incident, two male juveniles were cooking breakfast in the kitchen, according to Lt. Rio Amon-Wilkins in an interview with Hawaii News Now. There were no adults present. Amon-Wilkins said he believed the parents were at work.

When emergency responders arrived on the scene, a neighbor was performing CPR on the girl, who later died at Hilo Medical Center.

Amon-Wilkins said that a 14-year-old was taken into custody as part of the investigation and later released to child protective services.

The incident was classified as manslaughter. Amon-Wilkins stressed that was “very preliminary.”
