A Kasey Alert is active for 23-year-old Hunter Billen-Mills, an Oklahoma City man last seen around 4 a.m. Wednesday, September 16, 2026, after authorities said he recently stopped taking medication tied to a heart condition and several mental health diagnoses. Troopers say he may be behind the wheel of a silver 2021 Subaru Forester bearing Oklahoma license plate QCK827, and officials have not said what he was wearing when he disappeared.
The Oklahoma Highway Patrol activated the alert on behalf of the Oklahoma City Police Department, according to News 9. Per authorities, Billen-Mills has a mental health condition, a heart condition, obsessive-compulsive disorder, rage, anxiety, a history of cutting, and bouts of psychosis, and he stopped taking his medication recently. He is described as 6 feet tall, weighing about 170 pounds, with brown hair and brown eyes.
How the Kasey Alert System Works
The alert draws its authority from a 2023 state law built specifically for cases like this one. Oklahoma Governor Kevin Stitt signed House Bill 1077, the Kasey Alert Act, into law in May 2023, establishing a statewide alert framework for critically missing adults between the ages of 18 and 59 that took effect that November, according to the Oklahoma Policy Institute. Before that law, Oklahoma's missing person notification framework relied on the Silver Alert Act of 2009, which restricted public adult alerts mainly to seniors 60 and older with cognitive or health impairments, according to Hoodline's earlier report on a separate missing person case.
Under Oklahoma Statutes Title 63 § 1-1990.12, local police receiving a report of a critically missing adult must immediately enter that person into the FBI's National Crime Information Center database, conduct an investigation, and determine that sufficient information exists to issue a Kasey Alert, per Justia Law. The Oklahoma Department of Public Safety is responsible for developing and implementing the statewide alert system.
Named After a Cherokee Nation Man Whose Case Went Unanswered
The alert system carries the name of Kasey Russell, a 29-year-old Cherokee Nation citizen who went missing in June 2016. His remains were found six years later, in 2022, just a quarter-mile from where he was last seen, after no public emergency alert had ever been issued at the time of his disappearance, according to 5NEWS KFSM. The Kasey Alert system addresses a gap that had left adults between 18 and 59 without any dedicated statewide notification system.
That gap carried added weight in Oklahoma, where 2018 federal data cited in state policy research showed the state ranked among the top 10 for missing and murdered Indigenous people cases, with Oklahoma City itself ranking among the top 10 U.S. cities for unrecorded cases involving missing Indigenous women, per the same Oklahoma Policy Institute research. Oklahoma later passed Ida's Law in 2021 and the Kasey Alert Act two years later.
Recent Cases Show the Alert in Action
The system has also been used in a case involving a Broken Arrow man, according to 102.3 KRMG. Hoodline has also covered other missing-person cases, including one case and another case.
Anyone who sees Hunter Billen-Mills or has information about his whereabouts is asked to call 911.
