San Marcos PD works with local authorities during investigation

(San Marcos) –Over the past three months, San Marcos Police Narcotics investigators worked a joint investigation that put a significant amount of methamphetamine out of circulation and landed two traffickers behind bars.

Beginning in October, SMPD partnered with the Seguin Police Department CASE Unit and the Guadalupe County Sheriff’s Office Narcotics Division to target 48-year-old Karin Erika Mince, a known meth distributor operating in the city of Seguin and across Hays and Guadalupe counties. That investigation led to the seizure roughly 14 ounces of meth and 7.5 grams of cocaine.

The case did not stop there.

Follow-up investigation identified 36-year-old Marcos Antonio Hernandez, an associate who was later caught delivering a full kilogram of meth during a controlled operation in December. Additional search warrants uncovered another half-kilo of meth, counterfeit pills believed to contain fentanyl, and other drugs.

According to San Marcos PD, this was not a solo effort. These arrests happened because agencies worked together, shared intelligence, and committed real resources over months, not days.

The San Marcos Police Department sincerely appreciates the participation and assistance provided by both the Seguin Police Department and the Guadalupe County Sheriff’s Office. Both agencies allocated significant resources and man-hours that resulted in the safe and successful resolution of this investigation.

Further gratitude is also extended to the Kyle Police Department, the Hays County Sheriff’s Office, and the Caldwell County Sheriff’s Office for the information and assistance that they provided during this investigation.

Drug trafficking cases are long, complex, and deliberate. This one removed a large supply of dangerous drugs from our region and shows what coordinated enforcement actually looks like.
