A tragic shooting in Waianae, Hawaii, late Saturday night resulted in four deaths and two injuries. The incident began when a 58-year-old man used a front loader to ram vehicles into a neighbor's home and then opened fire, killing three women and injuring two others. The suspect was subsequently shot dead by a 42-year-old resident of the home, who has been arrested on suspicion of second-degree murder. The front loader was found to be carrying 55-gallon drums with an unknown fuel, which the suspect had fired at. This incident is considered a neighbor-on-neighbor dispute, with a history of prior conflicts between the involved parties. The surviving victims, a woman in her 50s and a man in his 30s, are in serious condition, while another woman in her 30s or 40s is critically injured.
