EL PASO, Texas (KTSM) — Federal prosecutors in West Texas have filed 319 new immigration and immigration-related criminal cases in the past week, the U.S. Attorney’s Office for the Western District of Texas said.

Of those new cases, 110 were filed in El Paso, the U.S. Attorney’s Office said.

Charges were brought against human smugglers and undocumented migrants with past convictions for numerous DUIs, violent crimes, burglary and multiple prior removals, the U.S. Attorney’s Office said.

Among the new cases:

Convicted felon Martha Lopez, of Socorro, was charged with smuggling undocumented migrants. A criminal complaint alleges Lopez had arranged to pick up a group of four migrants in the early morning hours of May 19 near the intersection of Angus Drive and Carablanca Drive.

She allegedly fled at a high rate of speed as law enforcement vehicles responded. A U.S. Border Patrol agent conducted a traffic stop and Lopez was placed under arrest. Later that morning, USBP agents allegedly located two undocumented migrants at Lopez’s residence, which had previously been identified as a possible stash house. In 2005, Lopez was convicted for voluntary manslaughter and child cruelty, the U.S. Attorney’s Office said.

Yvette Yarelli Vasquez also faces human smuggling charges. Vasquez is the girlfriend of previously convicted migrant smuggler Yovani Garcia-Cruz, the U.S. Attorney’s Office said.

A criminal complaint alleges Vasquez was aware of Garcia-Cruz’s most recent alleged involvement in migrant smuggling and the money he was receiving. The complaint also alleges agents discovered proof-of-life videos and messages sent to Vasquez by Garcia-Cruz. Further investigation allegedly revealed a proof-of-life video depicting a female child saying she was in El Paso. Another video of the child allegedly shows the tattooed hand of Vasquez providing food for harbored children.

Convicted felon from Mexico Osiel Alfonso Marroquin-Morales was found nearly five miles west of the Fort Hancock Port of Entry. He’s been removed from the U.S. to Mexico twice, the last being on July 9, 2025, the U.S. Attorney’s Office said.

In 2014, Marroquin-Morales was convicted of a DUI, operating a motor vehicle without a license, and obstructing an officer in Tampa, Florida, for which he was sentenced to 45 days of confinement, the U.S. Attorney’s Office said.

In 2014, he was convicted in Indiana for causing death and serious injury while operating a motor vehicle while intoxicated, the U.S. Attorney’s Office said. He was sentenced to 10 years in prison.

Juan Santiago-Alavez, from Mexico, was found approximately half a mile west of the Tornillo Port of Entry. He was previously deported for the second time on Nov. 11, 2025, and has six DUI convictions in his criminal record, along with convictions for domestic battery, false imprisonment, violating a court order, and vandalism, the U.S. Attorney’s Office said. He now faces a charge for illegal re-entry.
