Gas Line Explosion Lawsuit Filed After Deadly Dallas Blast

Two lawsuits have been filed after the deadly Dallas gas line explosion that destroyed a building at The Clyde apartments in Oak Cliff on May 28, 2026, killing three people and injuring five others. Both name Atmos Energy Corporation, and the second sweeps in the drilling contractor, the property owners and manager, and the developer that ordered the soil work that struck the line. Under Texas law, other residents and families have two years from the date of the blast to bring their own claims.

What Happened at The Clyde

The explosion occurred around 1:30 p.m. on May 28, 2026, at The Clyde apartments near East 9th Street and North Patton Avenue.¹ A geotechnical crew from Barba Drilling Co. LLC was taking soil samples on the property when it struck a natural gas pipeline. The gas ignited into a five-alarm fire that consumed the 20-unit building; 19 of the units were occupied.²

Three people were killed: 81-year-old community activist Sylvia Collins, Marisol Perez, and her 18-month-old son, Erik. Five others were injured, some with severe burns and smoke inhalation.³ Debris landed across the street and windows shattered in nearby buildings.¹

The Lawsuits Filed So Far

Ponce Mendoza v. Atmos Energy

The first suit was filed on May 29, 2026, in Dallas County by Kherkher Garcia LLP on behalf of Onecimo Ponce Mendoza, a resident who suffered severe burns and smoke inhalation.³ It names Atmos Energy as the sole defendant and alleges the company failed to properly monitor conditions at the complex, failed to warn residents of the danger associated with a gas leak, and routinely operated in an unsafe manner.¹ Attorney Jesus Garcia Jr. said the firm was seeking “maximum damages.”

Collins v. Atmos Energy et al.

On June 1, 2026, Hamilton Wingo LLP filed a wrongful death suit on behalf of Michelle Collins, Sylvia Collins’s daughter.⁴ It names six defendants:

Atmos Energy Corporation, the natural gas utility serving the area.
Barba Drilling Co. LLC, the subcontractor whose rig struck the line.
Sir Julian LLC and Samuel A. Aflalo, the owners and operators of The Clyde.
Revival Property Co. LLC, the Dallas-based property manager.
O-SDA Industries LLC, the prospective buyer that commissioned the soil work.

ECS Companies, the engineering firm that hired Barba Drilling, is identified as an “anticipated defendant” expected to be added later.²

The Collins suit seeks at least $1 million in damages for physical pain, fear of impending death, mental anguish, and physical impairment.⁵ It accuses all defendants of gross negligence and alleges that residents had reported the smell of gas in the days before the blast, and that those reports were not acted on.⁶ At a June 2 press conference, attorney Chris Hamilton said the legal team had “already collected crucial evidence that will ultimately help produce a clear picture of exactly who’s responsible, as well as the magnitude of the harm and suffering caused by this inexcusable gross negligence.”⁴

How the Gas Line Was Struck

The drilling was part of a geotechnical survey ordered by O-SDA Industries LLC, an Austin real estate developer that was buying the property to build an 82-unit senior housing project called “Rosette Park.”² O-SDA hired ECS Limited, based in Carrollton, to prepare the report, and ECS subcontracted the drilling to Barba Drilling.⁷

ECS filed a request with Texas811 on May 21, 2026, to have underground gas lines marked before work began on May 26. Markings were visible at the site when the rig struck the line. At 12:57 p.m. on May 28, eight minutes after the explosion, ECS reported the “nicked gas line” to Texas811, noting that “previous markings are visible.”⁸ A charred truck registered to Barba Drilling was found at the scene.

In the year before the explosion, Dallas recorded 924 “Grade 1” major gas leaks, the most severe classification, and nearly half were caused by third-party contractors digging into the ground.⁷

Why Atmos Energy Is at the Center

Atmos Energy’s public position is that an “unrelated construction company” damaged the pipeline while boring for soil samples.¹ The Collins complaint pushes back hard on that framing, alleging that Atmos “notoriously has an unusually high rate of leaks, including an excessive rate of third-party strikes, and a known history of poorly maintained gas lines and explosions causing serious injury and death in North Texas.”²

That allegation has recent regulatory backing. In January 2026, the National Transportation Safety Board released a report on a series of January 2024 natural gas explosions in Jackson, Mississippi, finding that Atmos Energy’s “inadequate leak management program” and “inadequate integrity management program” were the probable causes. The NTSB concluded that Atmos had allowed known leaks to persist for at least eight weeks, misclassified them as “nonhazardous,” and failed to adequately educate residents and first responders on how to react to gas odors. The agency issued ten new safety recommendations directed at Atmos, including mandates to replace mechanical couplings in areas with expansive soils, require weekly monitoring of leaks in adverse conditions, and transition from relative-risk models to probabilistic risk models.⁹

Violation Tracker records show Atmos has accumulated at least $12.8 million in penalties across 33 enforcement actions from federal and state agencies. The Texas Railroad Commission alone has imposed environmental violation fines on the company ranging from several thousand dollars to $95,000.¹⁰

What the NTSB Investigation Could Mean

The NTSB deployed a team of eight investigators to The Clyde site, and as of early June 2026 the official cause had not been determined. Natural gas service in the immediate area remained shut off.³

The NTSB’s final report is likely to shape the litigation. The agency’s reports are admissible in civil and criminal proceedings, and virtually all factual materials it collects can be used in court. The final report documenting probable and contributing causes is what one legal practice describes as a “blueprint for future litigation.”¹¹ Legal counsel for claimants and insurers are barred from participating as party representatives during the investigation, which gives the factual record an air of independence that makes it powerful evidence at trial.

What Victims and Families Can Recover

Suits like the two filed here typically stack several legal theories:

Negligence, used to hold utilities, contractors, and property owners liable for failures in maintenance, inspection, or response to reported gas odors.
Premises liability, aimed at landlords and property managers who fail to maintain safe gas systems or ignore tenant complaints about the smell of gas.
Product liability, when defective valves, regulators, or connectors contributed to the blast.
Gross negligence, a higher standard that, if proven, opens the door to punitive damages designed to punish particularly reckless conduct.

The Collins complaint casts a wide net for exactly this reason: it targets the utility for failing to respond to warnings, the contractor for damaging the line, the property owners for failing to protect tenants, and the engineering firm and prospective buyer for ordering work that was carried out unsafely.²

Victims can seek compensation for medical expenses, including long-term burn treatment and reconstructive surgery, along with lost wages, pain and suffering, permanent disfigurement, emotional distress, and property damage. When a family member is killed, survivors may file a separate wrongful death claim. Where conduct is reckless or willful, punitive damages may also be available.

In Texas, the statute of limitations for both personal injury and wrongful death is two years from the date of the incident. For anyone injured at The Clyde, or for families of those killed, that deadline is May 28, 2028. The two suits already on file were brought within days of the explosion, but other residents still have time to bring their own claims, and each additional plaintiff will be judged on the facts of their own injuries and losses.

Whether federal pipeline safety violations played a role in the blast is a question the NTSB investigation may answer. When such violations are established, through NTSB findings, PHMSA audits, or state enforcement, they serve as powerful evidence of negligence in civil litigation, often making the question of liability straightforward and leaving the size of damages as the main fight.
