San Antonio police are asking the public for help finding a 46-year-old woman with a diagnosed medical condition who vanished over the weekend near the city's medical center. Evonne Marie Llanes was last seen Saturday in the 4500 block of Medical Drive, and officers have not said what happened to her since.
According to the San Antonio Police Department, Llanes was last seen on the city's northwest side before officers issued a public call for assistance the following day, as reported by KSAT. She was last seen wearing a white shirt and blue jean shorts, and police describe her as 5 feet 3 inches tall with brown hair and brown eyes. Investigators say she has a diagnosed medical condition, though the outlet did not specify what it is.
Additional physical details have since emerged to aid identification efforts. As reported by KENS 5, Llanes weighs approximately 350 pounds, has a light complexion, and features two distinctive tattoos: a name on her left arm and a Pink Panther design on her right wrist. Those markers, combined with her height and clothing description, give the public specific details to watch for.
Why She Was Near the Medical Center
The block where Llanes was last seen sits inside San Antonio's South Texas Medical Center district, immediately adjacent to major health infrastructure including University Hospital, according to the same outlet's earlier local reporting. The area sees heavy daily medical traffic, high foot traffic, and continuous emergency vehicle activity, which could complicate efforts to pin down her exact movements before she disappeared.
The San Antonio Police Department is urging anyone with information to call the Missing Person Unit at 210-207-7660. SAPD's Missing Persons Unit operates under a policy requiring no waiting period before officers file a report for someone missing within city limits, according to the City of San Antonio, countering a common misconception that families must wait 24 hours before reporting a loved one missing.
Why No Statewide Alert Was Issued
Llanes's case has not triggered a statewide Silver Alert, and the reason comes down to her age. Under Texas Government Code § 411.382, Silver Alerts are strictly limited to missing adults 65 or older, or those diagnosed with Alzheimer's disease and a documented mental impairment confirmed by a physician, per FindLaw. At 46, Llanes falls outside that threshold regardless of her medical condition.
She could potentially qualify for a different tool: the Texas Department of Public Safety's Coordinated Law Enforcement Adult Rescue, or CLEAR, Alert program. Enacted in 2019, CLEAR Alerts are designed to help locate missing adults between 18 and 64 who are believed to be in imminent danger of injury or death, according to the Texas Department of Public Safety. Whether Llanes's case meets that imminent-danger threshold has not been publicly stated by police.
Regional guidelines from the Texas Center for the Missing add another layer: activating an Endangered Missing Persons Alert for an adult with an intellectual or developmental disability requires written medical documentation on letterhead from a licensed physician or psychologist. Absent that paperwork or a formal CLEAR Alert designation, San Antonio police are instead relying on local bulletins, database entries, and media coverage to spread the word.
The Scale of Missing Persons Cases Locally
Cases like Llanes's are far from rare in San Antonio. Law enforcement agencies in the city receive an average of nine missing person reports every single day, according to reporting by the San Antonio Report. That volume is part of why police lean so heavily on public sharing and tips to move cases forward quickly, particularly for adults who do not meet the criteria for automated highway alerts.
Behind the scenes, elevating a case like this to statewide law enforcement databases requires specific administrative steps. Listing a missing adult on the state's official online bulletin requires officers to first enter the subject into the National Crime Information Center system and submit a completed MP-3 form, according to the Texas Department of Public Safety. The Bexar County Sheriff's Office has also reminded the public that anyone who knowingly harbors or conceals a person listed as missing can face criminal charges under Texas law.
As of publication, San Antonio police have not released further updates on Llanes's whereabouts. Anyone with information is asked to contact the department's Missing Person Unit.
