A 33-year-old woman was stabbed to death on a Kaneohe street early this afternoon, allegedly by her boyfriend who then drove up the H-3 freeway and jumped to his death, according to police.

Police said the couple argued last night and the woman left their residence on Kapunahala Road. The woman returned today with her mother to collect her belongings and an argument ensued.

Just after 12:30 p.m., police were called to the address on a criminal property damage report but before they arrived the boyfriend, 27, had assaulted the mother and chased his girlfriend onto Kapunahala Road where he stabbed her multiple times, according to police.

By the time officers arrived, the suspect had fled in the woman’s Toyota SUV, which he drove up H-3. He pulled the SUV over and jumped off the freeway to his death. He was pronounced dead at the scene.

The 33-year-old woman was taken by ambulance to a hospital where she was pronounced dead, according to a spokesman for the city’s Emergency Services Department.

The mother, whose age was not given, was treated for minor injuries at the scene and released.

This is the second murder-suicide in a month on Oahu. On Aug. 20, Kristine Cass, 46, and her daughter Saundra, 13, were shot to death in their Makiki home by the mother’s former boyfriend, Clayborne Conley.

Conley, a former Hawaii National Guardsman with a history of violent behavior and mental instability, shot himself after killing the mother and daughter.
