A six-year-old narcotics detection dog named Archer died after being left unattended in a patrol car on Sept. 4, the Hawaii Police Department said, prompting promises of criminal and administrative investigations and a review of K9 policies.
Archer, a Belgian Malinois–German Shepherd mix who began serving with the department in 2021, worked in the Vice Section based in West Hawaii and partnered with Officer Sidra Brown, the department's only female K9 handler. Interim Police Chief Reed Mahuna described the death as "a preventable tragedy," and said the department is "committed to accountability and making sure something like this never happens again."
Mahuna said a "thorough criminal and administrative investigation will be conducted" into the circumstances surrounding Archer's death. The department also said it will undertake an "extensive review" of its K9 policies to identify and address any procedural gaps. Officer Brown, who has been with the Hawaii Police for more than a decade, was described by the department as "devastated".
Archer was trained to detect small amounts of narcotics hidden in vehicles, buildings and parcels and participated in numerous drug-bust operations, officials said. The department thanked the community for its support as it mourned the dog, saying Archer was a "loyal and dedicated partner." According to information on the department's website, Archer was originally from Hungary and enjoyed "looking handsome and eating mangoes."
The department said temperatures reached about 90°F on the day Archer died. Experts and safety organizations warn that vehicles can heat rapidly and become significantly hotter than ambient temperatures even with windows cracked. For example, on a 90°F day the interior of a car can reach roughly 124°F in about 30 minutes. State Farm estimates that hundreds of dogs die from overheating in vehicles each year.
In its statement, the department urged the public to be mindful of the risks of leaving animals unattended in vehicles. Mahuna said dogs should not be left unattended in a vehicle "for any period of time." The department did not provide additional operational details about how long Archer was left in the vehicle or whether any personnel actions will follow the investigations.
The investigations, Mahuna said, will seek to establish the facts and determine accountability. The department's review of K9 protocols is expected to examine handling procedures, vehicle practices and training to prevent similar incidents in the future.
Archer's death has drawn attention to police and public-safety policies concerning working animals and the conditions under which they are transported and left in vehicles. The Hawaii Police Department said it will report additional findings as the inquiries progress and that it remains focused on both supporting staff and preventing future losses of K9 partners.
