Former Sonora police chief pleads guilty in Val Verde County assault case

A former Sonora police chief whose case drew in Del Rio investigators and the Texas Rangers resolved the matter in Val Verde County court. Donald Edward Fernandez Jr. pleaded guilty in Del Rio to misdemeanor family violence assault and received two years of deferred adjudication community supervision, closing a case that began with allegations he assaulted a pregnant woman in 2022.

The plea matters because deferred adjudication is not the same as an ordinary sentence or a straight acquittal. Under that arrangement, a judge places a defendant under court supervision, and if every condition is met, the charge can later be dismissed without a conviction. The case and its sentence can still remain part of the public record, which is why outcomes like this can continue to affect hiring, licensing and other public-facing roles long after the courtroom hearing ends.

Fernandez had originally faced two third-degree felony counts of assault of a pregnant person after an arrest in September 2025. Del Rio police and the Texas Rangers investigated the allegations, and Fernandez later turned himself in at the Val Verde County Sheriff’s Office. Court records showed he posted a $10,000 bond and was released from the Val Verde County Jail on September 23, 2025.

The case also has a direct local tie for Del Rio and Val Verde County residents. The alleged incident that led to the indictment was said to have occurred in Val Verde County, and the plea was entered before 63rd Judicial District Judge Roland C. Andrade in the county seat. The reduction from felony charges to a Class A misdemeanor will sharpen debate over plea bargaining and how family-violence cases are handled in the local justice system.

Fernandez’s downfall also reshaped the small department he led. The City of Sonora fired him in early October 2025 after city manager Art Fuentes said Fernandez had been suspended pending an investigation and named Lt. Whitney Merket as acting chief. The Sonora Police Department says it has 25 sworn and non-sworn members, a size that makes the removal of a chief a significant operational and leadership disruption.

For Val Verde County, the case is about more than one officer’s career. Fernandez is a Del Rio native and a former Del Rio police officer, and the plea puts the focus back on accountability inside the law-enforcement ranks. Residents are likely to keep asking whether any complaints, internal reviews or warning signs surfaced while he was in command, and what that says about public confidence in the agencies charged with protecting the community.
