Authorities in Texas say a mother sold her 7-year-old son to two men and had begun the process of selling her two daughters, ages 2 and 3, at the time of her arrest.

According to Fox News, 29-year-old Esmeralda Garza was arrested on Friday on suspicion of third-degree felony sale or purchase of a child.

Texas Department of Public Safety special agents reportedly took the mother into custody while serving a search warrant at a Corpus Christi home last week.

During their investigation, they also arrested two other individuals.

It was unclear from initial reports whether the man and woman arrested along with Garza were suspected of involvement in the alleged sale of her children or alleged drug activity inside the home.

Special agents with the state law enforcement agency entered the home to serve the search warrant and say they found the male child who had recently been sold by his mother, as reported by KIII.

The investigation led them to the discovery of the two additional children, both girls, who were allegedly also going to be sold.

After her arrest, officers transported Garza to the Nueces County Jail where she was booked with bond set at $100,000.

According to KRIS TV, the other two suspects arrested were also booked into the Nueces County Jail. The charges against them were not immediately announced.

Court records indicate additional charges are expected to be filed in connection with the raid, though it was unclear what they might include.

Authorities say the investigation remains ongoing.
