San Antonio woman jailed in Goliad County after deputies find stolen mail and more than 50 cards

Traffic stop leads to discovery of alleged mail theft and identity-related offenses

A San Antonio woman is facing multiple criminal charges in Goliad County after deputies said a traffic stop led to the discovery of stolen mail, payment cards and personal identification documents tied to numerous individuals.

The arrest centers on Marisa Magana, who authorities said was driving a rented U-Haul when a sheriff’s office sergeant stopped the vehicle for a traffic violation. Investigators reported finding a large amount of property believed to be stolen, including credit and debit cards, mail addressed to different people and locations, and an account-style notebook containing personal and financial details connected to multiple individuals. Deputies also reported recovering three passports.

Charges cite large numbers of alleged victims

Magana was booked on charges that include alleged unauthorized possession or use of credit or debit cards involving more than 50 people, possession of identifying information involving 10 to 50 people, and mail theft. Authorities did not publicly detail whether the cards or identifying information were linked to confirmed fraudulent transactions, but described the volume of items recovered as significant.

Investigators said some of the recovered mail appeared to originate from both San Antonio and Goliad County, indicating the alleged conduct may have crossed county lines. Deputies said she was taken into custody shortly after the traffic stop.

Federal agencies may review the case

Local investigators said they are coordinating with federal authorities, including the Department of Homeland Security and the U.S. Postal Service, as the investigation continues. Mail theft can trigger federal jurisdiction depending on the circumstances, and identity-related allegations can also result in state and federal prosecutions when evidence supports it.

How mail theft investigations typically proceed

Cases involving large quantities of mail, payment cards and personal data often expand beyond an initial arrest as investigators work to:

• identify victims and notify them,
• confirm the origin of recovered items and how they were obtained,
• determine whether counterfeit cards, altered identification documents or organized theft patterns are involved, and
• trace whether financial losses occurred, including attempted or completed purchases and account access.

Criminal charges are allegations. A defendant is presumed innocent unless and until proven guilty in court.

What happens next

The case is expected to move through the Goliad County court system as prosecutors review the evidence gathered during and after the traffic stop. Additional charges are possible if investigators connect the recovered items to specific theft reports, documented financial losses, or broader patterns of mail-related crime.
