A Silver Alert is active for Robert Obourn, a 67-year-old South Oklahoma City man who suffers from kidney failure and requires daily medication. Obourn, described as a white male standing 5-foot-9 and weighing 132 pounds with gray and brown hair, was last seen at his residence near Southwest 129th Street and May Avenue on August 31.
Police are asking anyone with information about his whereabouts to call 911 immediately rather than use non-emergency channels, according to KFOR. Obourn has been diagnosed as autistic and also lives with high blood pressure in addition to his kidney failure, and the station reported that he requires daily medication. The station's report does not explain what caused the gap between when Obourn was last seen and when the Silver Alert was made public Tuesday.
A Medical Clock Running Against the Search
The stakes tied to Obourn's missing medication are severe. Research compiled in PMC / National Institutes of Health shows that for people living with end-stage kidney failure, a single missed treatment carries a 1.4-fold increased risk of hospitalization and a 2.2-fold increased risk of death within 30 days. Untreated kidney failure can quickly lead to dangerous fluid retention and electrolyte buildup, underscoring why investigators consider Obourn's case time-sensitive.
His autism diagnosis adds another layer of risk that search teams must account for. A nationwide study published in Pediatrics and cited by the CDC found that 49 percent of individuals on the autism spectrum engage in wandering or elopement from safe settings after age four, with 53 percent going missing long enough to cause serious concern. The National Autism Association has found that accidental drowning accounts for over 70 percent of lethal outcomes in these wandering cases, followed by fatal traffic accidents at 18 percent, which is part of why searchers for missing autistic individuals routinely check nearby waterways and roadways.
Oklahoma's Alert System and the Neighborhood in Question
Oklahoma's Silver Alert framework dates to the Silver Alert Act of 2009, which authorized law enforcement to issue statewide emergency alerts for missing seniors 60 or older with dementia or cognitive impairments that pose a credible threat to their safety, according to Justia Law. The Oklahoma Department of Public Safety source outlines Silver Alert criteria, per Oklahoma.gov.
The area near Southwest 129th Street and South May Avenue where Obourn was last seen sits in South Oklahoma City, according to geographic data from Geographic.org. The intersection is the location identified in reports about the case.
Recent Oklahoma Missing-Person Reports
The available reporting cited here does not establish a broader pattern of recent Silver Alerts across the Oklahoma City metro area. The provided material does not verify the linked Del City Silver Alert report or the separate report about a 74-year-old who vanished on foot in Northwest Oklahoma City and was later located safely. The provided material also does not verify a figure for Oklahoma's active missing-person cases in NamUs or a per-capita comparison with national averages.
The provided material does not document a federal initiative involving the U.S. Department of Health and Human Services, the Department of Justice and FEMA to address missing autistic individuals or describe a connection to FEMA's Integrated Public Alert and Warning System. Anyone who spots Robert Obourn or has information on his location is urged to call 911 right away.
