SAN ANTONIO, Texas – An AMBER Alert has been issued for a missing teen from San Antonio.

What we know:

Officials said they are looking for 17-year-old Briana Guerra. She was last seen on March 2 in the 1100 block of West Commerce around 8 a.m.

Guerra is described as a white female, with brown eyes, brown hair, about 5’6, and 130 pounds.

She was last seen wearing a blue shirt, jean shorts, blue Crocs, and has a marigold flower with a Roman numeral tattoo on her left arm.

If anyone has any information on her whereabouts, call the Bexar County Sheriff’s Office or 911 immediately.

The search for 17-year-old Briana Guerra of San Antonio, Texas, has taken a potentially significant turn with a new witness account emerging from the area near the Bexar County Jail. An employee working in the vicinity of the 1100 block of W. Commerce Street—the exact location where Briana was last officially seen around 8 a.m. on Monday, March 2, 2026—reports observing a girl matching her description that morning.

The witness recalls seeing a teen in a blue shirt and shiny Crocs (consistent with the Amber Alert description of blue glitter Crocs) standing near the curb. She appeared to be looking down at the ground, then bent to retrieve or examine a shoe in the bushes. This seemingly minor detail aligns precisely with the timeframe of her disappearance shortly after release from custody. Investigators are now evaluating whether this sighting represents Briana in the immediate post-release period, possibly disoriented or in distress during her ongoing mental health episode.

Briana had been arrested the previous day on a family violence charge following a mental health crisis that began Saturday evening after she missed a dose of prescribed medication. She had attended a teen event or conference at Community Bible Church, where her mother, Raquel Guerra, picked her up amid the episode. Despite family pleas to avoid arrest and instead provide medical intervention, she was booked into the Bexar County Jail around 1:30 p.m. Sunday due to her age being processed as an adult under Texas law.

She was released early Monday morning—around 8 a.m.—near the jail but vanished soon after. Her phone disconnected shortly after custody intake and has remained offline, complicating tracking efforts. Briana has no cell phone with her, per family statements, and has been without her medications for over 72 hours, raising grave concerns for her safety and well-being.

The Amber Alert, issued by the Texas Department of Public Safety on March 3, describes Briana as 5’6″, 130 pounds, with brown hair and brown eyes. She was last seen wearing a blue short-sleeved shirt, denim shorts, blue glitter Crocs, and has a distinctive tattoo of a marigold flower with Roman numerals on her left arm, plus a nose piercing. Authorities believe she may be in grave or immediate danger.

This witness report adds urgency to the search, as it places her in the immediate area post-release and suggests possible confusion or vulnerability—perhaps related to her untreated mental health state or the trauma of recent family losses. Briana is the younger sister of Matthew Guerra, who was fatally shot alongside his pregnant girlfriend in a separate incident in December 2023. She had previously run away from home once in summer 2024, about six months after her brother’s death, highlighting ongoing family challenges.

The Bexar County Sheriff’s Office (BCSO) continues the investigation, urging anyone with information to contact them at (210) 335-6000 or via [email protected]. The family has publicly criticized jail handling of mental health cases, calling for better coordination between law enforcement, mental health services, and crisis intervention.

This case underscores critical gaps in supporting youth in mental health crises, particularly when intersecting with the justice system. Resources for immediate help include:

988 Suicide & Crisis Lifeline: 24/7 confidential support for emotional distress or crisis.
National Domestic Violence Hotline (if relevant to family dynamics): 1-800-799-7233 or text “START” to 88788.
Local Texas crisis services and Bexar County mental health resources.

Community members and advocates continue to share the Amber Alert widely, hoping this new witness detail leads to Briana’s safe return.
