G3 Missing Persons serves San Antonio and Bexar County with a licensed Texas PI who works missing persons cases exclusively — from runaway investigations to cold cases and suspected foul play.
San Antonio is the second-largest city in Texas and the seventh-largest in the United States, with a population exceeding 1.5 million and a metro area that reaches well beyond Bexar County into Comal, Guadalupe, and surrounding counties. It is also a city defined by its geography — positioned along the I-35 corridor between Austin and the Texas-Mexico border, and home to Joint Base San Antonio, one of the largest military installations in the country.
That combination of factors — large population, major transportation corridor, significant military presence, and proximity to the international border — creates a missing persons landscape that demands specialized investigative capability. G3 Missing Persons provides exactly that: a licensed Texas private investigator who handles missing persons cases exclusively, with the OSINT tools, database access, and law enforcement coordination that these cases require.
The I-35 corridor that runs through San Antonio is one of the most significant north-south transportation routes in the United States, connecting the Texas-Mexico border at Laredo to Austin, Dallas / Fort Worth, and beyond. For missing persons investigators, this corridor is critically important. It is a known route for human trafficking, and it provides rapid transit access that can move a missing person hundreds of miles in a matter of hours.
San Antonio’s position roughly 150 miles from the border adds another dimension to certain case types. Cases involving suspected trafficking, involuntary disappearances, or situations where a missing person may have been taken across international boundaries require an investigator with specific experience and the right federal agency relationships. Steve Gelinske has worked cases with these dynamics and coordinates directly with agencies operating along the border corridor.
Joint Base San Antonio — which encompasses Fort Sam Houston, Lackland Air Force Base, and Randolph Air Force Base — brings a substantial active-duty and veteran population to the area. Missing persons cases involving military personnel or their family members often carry additional complexities, including jurisdictional questions between civilian and military law enforcement, frequent relocations that complicate trail reconstruction, and situations where a service member’s deployment history or access to resources creates unique investigative challenges.
G3 understands these dynamics and works within them. Whether coordinating with the San Antonio Police Department, Bexar County Sheriff’s Office, or military law enforcement, Steve brings the same focused, methodical approach to every case — adapting to the specific jurisdictional and operational realities of the situation.
G3 Missing Persons is headquartered in Dallas / Fort Worth, approximately four hours north of San Antonio on I-35. Steve Gelinske deploys directly to San Antonio when a case requires on-the-ground presence — and for urgent cases, that deployment can happen the same day.
The advantage of working with G3 over a generalist local agency is focus. Every resource G3 brings to bear — specialized databases, OSINT methodology, law enforcement relationships, and partnership with Search Investigations for field operations — exists for missing persons work. No other case types. No divided attention. When a San Antonio family hires G3, they are getting an investigator whose entire practice is built around finding people who are missing.
Every case type below represents a distinct investigative discipline. G3 brings specialized methodology to each one — from OSINT and database intelligence to field operations and law enforcement coordination.
