United States of America v. Shawn Nichole Zatloukal

Date: 04-15-2026

Case Number: 5:25-cr-00119

Judge: Andrew S. Oldham

Court: United States District Court for the Northern District of Texas (Lubbock County)

Plaintiff's Attorney: United States District Attorney's Office in Lubbock

Defendant's Attorney: Mike King

Description:
Lubbock, Texas, criminal defense lawyers represented the Defendants charged with drug trafficking.
Shawn Nichole Zatloukal was a member of a larger methamphetamine trafficking organization responsible for distributing large quantities of methamphetamine in the Lubbock area. She and her codefendants, all of Lubbock, were indicted in August 2025 and all later pled guilty to methamphetamine trafficking charges. Zatloukal was sentenced on Monday this week by Fifth Circuit Judge Andrew S. Oldham, sitting by assignment. The remaining defendants were sentenced by United States District Judge James Wesley Hendrix, who noted during co-defendant Jeremiah Arguijo’s sentencing hearing the staggering amount of drugs distributed by the organization. All were sentenced to lengthy prison terms:

Jeremiah “Chris” Arguijo, 40, was sentenced to 360 months;
Shawna Nichole Zatloukal, 55, was sentenced to 168 months;
Christopher Alan Nagella, 59, was sentenced to 240 months;
Adam “Adan” Casas, Jr., 52, was sentenced to 97 months;
Benjamin “BJ” Hernandez, 46, was sentenced to 132 months; and
Nicholas James Westbrook, 45, was sentenced to 160 months.


“These lengthy prison sentences should serve as a warning of what lies ahead for those who distribute narcotics in the Northern District of Texas,” said U.S. Attorney Ryan Raybould. “We will be relentless in identifying and prosecuting drug traffickers, as we continue to focus on making the communities in which we live safer.”


“These sentences underscore our commitment to holding drug traffickers accountable for the harm they bring to our communities,” said DEA Dallas Special Agent in Charge, Joseph B. Tucker. “The DEA Lubbock Resident Office and our law enforcement partners throughout the region will continue to aggressively pursue those that distribute this poison and never waver as we seek to protect the neighborhoods we call home.”


According to court documents, the investigation lasted several months and culminated in the execution of multiple search warrants on July 22, 2025. During these searches, agents located several pounds of methamphetamine, multiple firearms, and several thousand dollars in currency. In total, agents seized over 4,200 grams of methamphetamine during this investigation.
The Drug Enforcement Administration, the Bureau of Alcohol, Tobacco, Firearms, and Explosives, Homeland Security Investigations, the Lubbock Police Department, the Lubbock County Sheriff’s Office, and the Texas Department of Public Safety conducted the investigation. Assistant U.S. Attorney Sean Long prosecuted the case.

JUDGMENT as to Shawna Nichole Zatloukal (2), Count(s) 1, Dismissed on Govt's Motion.; Count(s) 3, Imprisonment with BOP for a term of 168 months to run concurrently with any sentence imposed in Case Nos.
