In the early morning hours of September 2, 2023, 36-year-old Adrian Barbosa of New Braunfels was shot and killed in downtown Seguin. Officers with the Seguin Police Department responded about 2:11 a.m. to reports of gunfire in the 100 block of North River Street and found Barbosa on the ground with a gunshot wound. First responders attempted lifesaving measures, but a Justice of the Peace pronounced him dead at the scene.

The Seguin Police Department’s Criminal Investigation Division named 24-year-old Isaac Mesa Jr., also of New Braunfels, as the shooter. Deputies from the Guadalupe County Sheriff’s Office arrested Mesa and he was booked on a charge of murder with bond set at $1 million. The case went to a jury trial in the 456th District Court in Guadalupe County; the jury convicted Mesa of murder and had begun the punishment phase but had not yet reached a sentence decision.

Anyone who knew Adrian, saw activity in downtown Seguin that night, or has information about the shooting is asked to come forward.
