A standoff between Hawaii island police and a lone gunman in Puna that lasted more than 12 hours today ended with the man killing himself.

Police said the standoff ended just before 1 p.m. when the man shot himself inside his vehicle. An autopsy will be conducted to determine the man’s exact cause of death. His name was being withheld until positive identification is made and notification of next of kin.

At about 12:20 a.m. today, officers responded to a report of gunshots at a home on Kamanu Street in the Hawaiian Beaches subdivision in lower Puna.

Upon their arrival, officers were confronted by a man with a gun seated in a vehicle parked in the driveway of a residence. Several shots were fired after police arrived. The resident of the home was able to leave without harm, police said.

The department’s Special Response Team responded to the scene, and crisis negotiators communicated with the gunman, who remained within his vehicle.

During the incident, police closed Puna Parkway and Papio Street from Kahakai Boulevard, cutting off access to Kamanu Street, and neighboring residents were asked to leave the area for their safety.
