A 28-year-old woman has been missing for nearly two weeks after walking away from her family's home on San Antonio's far West Side in the middle of the night, and the Bexar County Sheriff's Office says she may be in danger. Elisha Domonique Johnson was last seen at her residence in the 14600 block of Potranco Road on August 21, when she left home while her family was asleep. Her whereabouts remain unknown.
The sheriff's office made its public appeal for help locating Johnson nearly two weeks after she vanished, according to a Bexar County Sheriff's Office post shared on Facebook. Johnson is described as 5 feet 2 inches tall, weighing 180 pounds, with brown hair and brown eyes. Investigators are asking anyone with information about her whereabouts to call the sheriff's office at 210-335-6000 or email its Missing Persons Unit at [email protected].
Why No Statewide Alert Went Out
The nearly two-week gap between Johnson's disappearance and the public bulletin reflects the narrow legal window built into Texas's alert system for missing adults. State law allows a Coordinated Law Enforcement Adult Rescue, or CLEAR, Alert for missing adults between 18 and 64 only if a preliminary investigation confirms imminent danger or an involuntary disappearance, and only if the request is made within 72 hours of the person vanishing, according to the Texas Department of Public Safety. That window bridges the gap between AMBER Alerts issued for missing children and Silver Alerts reserved for senior citizens. Because Johnson disappeared on August 21 and the advisory did not go out until this week, the 72-hour deadline had already passed, leaving investigators to lean on social media bulletins, direct tips, and the state's regional teletype notification network instead of a broadcast alert.
That does not mean deputies waited to act. Under Texas Code of Criminal Procedure Article 63.009, local law enforcement agencies are required to accept missing person reports immediately, with no mandatory waiting period, per FindLaw. That dispels a common misconception that families must wait 24 to 48 hours before filing a report. Once a report is entered into the Texas Law Enforcement Telecommunications System, electronic advisories are automatically transmitted to police agencies within a 200-mile radius, notifying surrounding departments and sheriff's offices even when no public alert is triggered.
A Rapidly Growing Corridor, A Newer Investigative Unit
The 14600 block of Potranco Road sits in the 78245 ZIP code, in far West Bexar County, an unincorporated suburban area outside San Antonio city limits where the sheriff's office holds primary jurisdiction. The area has seen rapid housing growth along its major roadway corridors, and local reporting has found that missing-person investigations handled by Bexar County deputies this year have been heavily concentrated in fast-growing developments near US Highway 90 and Potranco Road.
That surge in cases prompted a structural change at the sheriff's office. In November 2025, the agency established a standalone Missing Persons Unit backed by $370,000 in county funding, according to the San Antonio Report. Before the unit existed, a single detective had been juggling as many as 600 open missing-person cases; the reorganization added a dedicated criminal investigator and a civilian clerk to handle case sorting and family communications.
Similar Cases Across the West Side
Johnson's disappearance echoes a string of recent cases handled by the same sheriff's office. In May, deputies sought the public's help finding 31-year-old Clarissa Rose Segura, who went missing from the west side of Bexar County after sending a final text message, her phone showing no active cellular service, according to KENS 5. In August, the agency asked for help locating 30-year-old Jacob Rigo Luna, who vanished from San Antonio's west side without a cellphone after contacting family from an unknown number saying he needed help; Luna was last heard from in late July near Marbach Road and SW Loop 410, KENS 5 reported.
The pattern has continued in the days immediately surrounding Johnson's case. Hoodline has reported on a missing teen from the same Far West Side area, and separately covered the case of Evonne Llanes, a missing San Antonio woman, along with a missing 16-year-old and an 18-year-old who vanished off Babcock Road with his phone off.
Legal Warning to the Public
No details have been disclosed about a vehicle, cellphone status, or a direction of travel in Johnson's case, and investigators have not said what led them to believe she may be in danger beyond stating that belief directly. As is standard in these advisories, the sheriff's office is reminding the public that intentionally concealing or harboring a reported missing person, without notifying law enforcement or legal guardians, can result in criminal prosecution under Texas law. Anyone with information on Johnson's whereabouts is urged to contact the Bexar County Sheriff's Office.
