Federal authorities say a Mexican national who illegally entered the United States multiple times was deported after allegedly attempting to give her newborn baby to another woman as payment for a debt owed to human smugglers.
A Missouri investigation involving local police, federal agents, and child welfare officials led to the deportation of a Mexican national accused of participating in a scheme to transfer custody of her newborn child to another individual.
According to U.S. Immigration and Customs Enforcement, Maria Lidia Valle-Hernandez, 28, was removed from the United States on May 11 following an immigration court order.
The case began in January 2024 after Valle-Hernandez gave birth at St. Joseph’s Hospital in Lake Saint Louis.

Authorities Say False Identity Was Used
Investigators said Valle-Hernandez registered at the hospital using a false name before delivering the child.
According to federal authorities, she intended for another woman, who was also unlawfully present in the United States, to claim the infant as her own.
After being discharged from the hospital, Valle-Hernandez allegedly gave the other woman her hospital identification wristband.
Authorities said the second woman then presented herself to hospital staff as the baby’s mother.
Concerned Report Sparks Investigation
The alleged scheme came to light after a concerned individual contacted the Lake Saint Louis Police Department.
Police then coordinated with hospital personnel, the Missouri Children’s Division, and Homeland Security Investigations.
Federal investigators ultimately determined Valle-Hernandez was the child’s biological mother.
Authorities said she repeatedly denied her identity until HSI agents confirmed who she was through fingerprint records.
Debt to Smugglers Cited as Motive
According to ICE, Valle-Hernandez later admitted her actions were motivated by financial difficulties and a debt she owed to human smugglers.
Federal officials said she hoped resolving the debt would allow her to bring another child from Mexico into the United States.
“Human trafficking and smuggling exist everywhere, even in quiet, low-crime communities such as Lake Saint Louis, Missouri,” said Homeland Security Investigations Assistant Special Agent in Charge Gregory Paris.
Paris said the case highlights the importance of cooperation between federal and local law enforcement agencies in combating smuggling and trafficking networks.
Prior Illegal Entry Attempts Documented
ICE said U.S. Border Patrol agents encountered Valle-Hernandez illegally crossing into the United States near Santa Teresa, New Mexico, five times in August 2022.
Authorities reported that she was returned to Mexico after each encounter, including twice on the same day.
More recently, Chesterfield police arrested Valle-Hernandez on a fourth-degree domestic assault charge in April.
ICE lodged an immigration detainer the following day and took her into federal custody.
Child Placed in Protective Custody
Following the investigation, Missouri Children’s Division took custody of the newborn.
Lake Saint Louis Police Chief Chris DiGiuseppi praised the cooperation among agencies involved in the case.
“We appreciate the collaboration with our federal partners to keep our community safe,” DiGiuseppi said. “Educating law enforcement, medical staff and the public on the indicators of human trafficking will ultimately aid in protecting victims and holding suspects accountable.”
The investigation remains closed following Valle-Hernandez’s deportation.
