A former Atascosa County corrections officer was booked into the same jail where he worked after being indicted on a child endangerment charge, according to jail and employment records reviewed by The Hawk’s Eye. The records show Diego Lucio Valdez was booked into the Atascosa County Jail on June 16, 2026. One day later, a termination letter from the Atascosa County Sheriff’s Office stated Valdez’s employment as a corrections officer was terminated effective June 16 because he had been incarcerated in the county jail. The letter listed the criminal offense as “Indictment — Abandon Endanger Child INT/KNOW/RECK/CRIM NEG.”

Court records from the 81st/218th Judicial District Court also list The State of Texas v. Diego Lucio Valdez. The case was listed on the Atascosa County criminal appearance docket for July 8, 2026. The docket shows the case was filed June 5, 2026, and set for a 9 a.m. appearance. Valdez has been charged, not convicted, and the records reviewed by The Hawk’s Eye did not include the indictment, arrest affidavit, or underlying facts alleged by prosecutors.  

The Arrest Is One Story. The Silence Is Another.

For former Atascosa County jail sergeant Esmeralda Mancera, the arrest itself is only part of the issue. Mancera says the bigger concern is the lack of transparency when allegations, arrests, or internal problems involve people connected to the same county systems responsible for enforcing the law. She believes the public should not have to piece together information from booking records, court dockets, and personnel paperwork to learn when a sheriff’s office employee has been arrested. In her view, the Valdez case raises a larger question. What does the public get told, when do they get told, and who decides what stays quiet?

The sheriff’s office’s own county webpage points residents to Facebook for “Public Information or Notices,” listing the Atascosa County Sheriff’s Office Facebook page as the place where those notices are disseminated.  Social media can be useful for alerts, arrests, road closures, and community updates, but it also raises questions about what gets posted, what does not, and how long important information remains visible to the public. In a case involving a corrections officer arrested and booked into the county jail, Mancera says residents should not have to depend on whether an agency chooses to make a Facebook post. She argues that serious matters involving sheriff’s office employees should be clearly, consistently, and publicly disclosed through official channels, not discovered later through court records, booking sheets, or personnel documents.  

Mancera has become a vocal advocate for accountability in Atascosa County, regularly using social media to question county systems, call attention to public records, and encourage residents to speak up about concerns they believe have been ignored. Her posts have focused heavily on transparency, the sheriff’s office, the jail, court processes, and what she describes as a pattern of issues that do not always receive public attention. She told The Hawk’s Eye that what began as her raising concerns internally eventually became a much wider fight for transparency. “My own experience showed me how difficult it can be to get answers, and that’s what motivated me to keep asking questions and encouraging others to come forward,” Mancera said.  

A Former Insider Now Asking Public Questions

Mancera is not speaking as someone unfamiliar with the inside of a jail. According to the Texas Commission on Law Enforcement information reviewed by The Hawk’s Eye, Mancera worked for the Atascosa County Sheriff’s Office from October 2017 through October 2022, as a jailer. Before working in Atascosa County, Mancera said she had experience in corrections in Oklahoma, worked with a reentry program in San Antonio, and handled extraditions before eventually joining the sheriff’s office.

Mancera says her time at the Atascosa County Sheriff’s Office was not always bad. She says that changed after she began documenting things she saw inside the jail and raised concerns internally. According to Mancera, she started writing down incidents, concerns, and situations that she believed did not seem right because she believed accountability mattered. She says that experience eventually shifted the way she viewed the jail, the sheriff’s office, and the county’s larger justice system.

Mancera alleges that after she raised complaints, including concerns involving sexual harassment and bullying, the focus turned toward her instead of the issues she believed needed to be addressed. She told The Hawk’s Eye that a use-of-force incident involving her had previously been cleared, but was later revisited and became the basis of a criminal case. Court records provided to The Hawk’s Eye show a motion to dismiss was later filed in her case, with the state citing “insufficient evidence.” The court granted the dismissal without prejudice on June 11, 2025.  

From Personal Experience To Public Advocacy

Mancera says that experience is one of the reasons she became more vocal online about Atascosa County. She says going through the system herself caused her to pay closer attention to evidence, court procedures, and how concerns involving officials or county employees are handled. She has also questioned whether residents always know enough about what happens behind the scenes in local government and law enforcement. That is why, she says, cases like Valdez’s should not be viewed as isolated incidents without asking more questions about transparency.

In the Valdez case, the sheriff’s office did take formal employment action after his incarceration. The termination letter states his employment as a corrections officer was officially terminated effective June 16, 2026, and it requested that he return county-issued property, including his identification card, employee access card, chits, and policy book. The letter was dated June 17, and signed by Deputy Chief Jose Mendoza, Jail Administrator, on Atascosa County Sheriff’s Office letterhead identifying Jake Guerra as sheriff. Those records show the agency acted internally, but Mancera says internal action is not the same as public transparency.  

Why The Case Matters Now

The Valdez case remains a criminal matter, and the charge listed in the records is an allegation. The public records reviewed by The Hawk’s Eye do not prove guilt, and Valdez is presumed innocent unless and until proven guilty in court. Still, the fact that a jailer was booked into the same jail where he worked creates a public-interest issue beyond the criminal charge itself. The question now is whether Atascosa County residents are getting enough information when the people working inside public safety agencies become the subject of serious criminal allegations.

Mancera says this is exactly why she continues to speak out. She believes residents should be asking more questions about the sheriff’s office, the jail, and county systems that often operate outside daily public view. To her, the Valdez arrest is not just another name on a docket or another booking sheet filed away in county records. It is one more example of what she says can remain hidden “in the back country roads of Atascosa County” unless someone keeps digging.

The Hawk’s Eye will continue following Valdez’s criminal case as it moves through court. We will also be taking a deeper look at Mancera’s time inside the Atascosa County Sheriff’s Office, the concerns she says she raised, the criminal case that was later dismissed against her, and the records she says changed the way she views accountability in Atascosa County. That in-depth story will examine her allegations, the documents connected to her case, and the larger transparency questions she says residents deserve to have answered. For now, the Valdez case has reopened a familiar question in Atascosa County. When something serious happens inside the system, how much does the public actually get to know?
