19 Hawai‘i Island police officers disciplined in 2025, latest legislative report shows

The latest Legislative Disciplinary Report reveals that 19 Hawai‘i Island police officers were disciplined in 2025, with three discharged, including two cases that have been forwarded to the Hawai‘i County Prosecuting Attorney.

The Hawaiʻi Island Police Department posted the latest report on its website on Thursday. Click here to see all posted legislative disciplinary reports.

“Data from our 2025 report to the Legislature does show a significant decrease in sustained misconduct cases compared with 2024,” Police Chief Reed Mahuna said. “This positive trend reflects our continued emphasis on training, supervision and accountability.

“While even a single incident of misconduct is one too many, I am encouraged by our officers’ commitment to upholding the public’s trust and we will continue working to improve.”

In 2024, 21 officers were disciplined, with eight cases forwarded to the county attorney’s office.

The discharged officers for 2025 were:

• Officer Mark Kaili: He committed criminal acts of burglary and assault. In June 2024, he pleaded no contest in Kona Circuit Court, where Judge Wendy DeWeese sentenced the former officer to one year of unsupervised probation, 30 days jail with credit for time served, and all further active jail suspended.

Assistant Chief Sherry Bird said Kaili first showed up on the 2024 annual report and remained on the 2025 report because the case is still going through a grievance process.

“Sometimes the disciplinary actions are amended during the grievance process,” Bird explained. “Once this process is completed, then he will no longer appear on the annual list.”

• Officer Troyson Reilly: He “failed to uphold departmental policies regarding professional conduct and responsibilities by commission of a criminal act.” The prosecuting attorney was notified in this case.

• Sgt. Wendall Carter: He failed to meet the standards expected of department personnel that constitutes conduct that is detrimental to the good order and discipline of the department. The sergeant was suspended for 10 days before being discharged.

The other officers were disciplined for a variety of reasons, including being untruthful, failing to turn on body cameras, violating pursuit policies, providing confidential information to a civilian, failing to comply with department policy for firearms discharge, and failing to follow a directive issued by his commander.

The longest suspensions for 2025 were 30 days, compared to the 2024 report, where Officer Noah Serrao was suspended for 50 days.

Serrao and Officer Blane Kenolio, who was also listed in the 2024 legislative report, were charged with crimes related to perjury and evidence tampering by the State of Hawai‘i Attorney General in January.

Noticeably not on the list was the name of a K9 handler who was transferred from her position on the Vice Section after her K9 partner Archer was left in a police vehicle parked at the Kona police station and died.

While no criminal charges were filed against the officer, Mahuna said the internal process in the case concluded just this month, saying: “I can not comment on the discipline as it is subject to the union grievance process at this time.”
