Investigators had not announced a cause Friday after a woman was pulled from the wreckage and taken to a hospital.
LAKE DALLAS, Texas — A house explosion in a Lake Dallas neighborhood Thursday evening destroyed a home, injured at least one person and forced nearby residents to leave while firefighters and utility crews secured the area.
Authorities said the blast happened around 7:05 p.m. in the 600 block of Moseley Street, just east of Lake Dallas Middle School. By Friday, investigators still had not said what caused it. The immediate stakes were both personal and practical: one injured resident had been flown to a hospital, several homes nearby were evacuated, and crews kept the block closed while they examined whether a gas-related problem or another failure may have triggered the collapse and fire.
Lake Cities Fire Department crews and Lake Dallas police were sent to the street after reports of a house fire. By the time responders arrived, the blast had already torn through the home and flames were moving through what remained of the structure. The house later collapsed. Police agencies from Lewisville, Corinth and Highland Village also responded as the fire burned into the night. On Friday morning, the wreckage still marked the center of a wide emergency perimeter. A city update said residents near the site were asked to leave out of caution while crews worked to make the area safe, with officials expecting many of them to return later that evening. Atmos Energy technicians were also at the scene as the investigation continued.
Officials confirmed that at least one person was injured, but they had not publicly identified the victim or described the person’s condition by Friday. Neighbors told local television stations they heard a violent boom that shook nearby homes and sent people running outside. Jacob Sahl, who lives two houses away, said he rushed toward the destroyed home after hearing what he described as a bomb-like blast. He told CBS Texas that he and others heard someone crying from the debris, moved rubble and pulled out a woman moments before the fire intensified. He said the woman was conscious and able to speak, and that her dog also got out alive. Authorities had not publicly confirmed those details Friday, and they had not said how many people were inside the house when it exploded.
The explosion struck a residential area near a public school and quickly drew attention across North Texas because of the force of the blast and the size of the debris field. Helicopter footage and on-the-ground video showed a home reduced to rubble, with firefighters still working hot spots after dawn. The event also came just days after two natural gas line strikes elsewhere in Lake Dallas led to evacuations and road closures near City Hall, adding to concern in the community. Even so, officials and Atmos Energy had not said those earlier incidents were connected to the house explosion. That left a key question unresolved Friday: whether the cause was related to natural gas service, a problem inside the home, or something else entirely.
By Friday, the investigation had expanded beyond local first responders. CBS Texas reported that the Texas Railroad Commission, which oversees pipeline safety in the state, had inspectors at the scene. Atmos Energy said its crews worked through the night with firefighters and emergency officials and that gas service to the area had been shut off as a precaution. The National Transportation Safety Board had not decided Friday whether it would open its own investigation. No criminal allegation had been announced, and no public hearing or court filing was tied to the blast as of Friday afternoon. The next steps were expected to include examining the debris, tracing utility lines and interviewing witnesses and residents who were home when the explosion happened.
For neighbors, the scene was still raw a day later. Some stood behind police tape looking toward the shattered lot, while others described the sound as unlike anything they had heard before. Jason Hughes told FOX 4 it was “the biggest explosion” he had ever heard and said the house was “pretty much gone.” Another resident told CBS Texas the blast felt like an airplane had hit the house. Those accounts helped explain why officers widened the perimeter and kept roads closed into Friday. Even without a confirmed cause, the images of splintered lumber, scorched debris and emergency crews moving carefully through the remains made clear how fast an ordinary evening on Moseley Street turned into a rescue and investigation.
As of Friday evening, officials still had not announced what caused the explosion or released a medical update on the injured resident. The next public milestone was expected to come after investigators and utility crews finish work at the scene and provide a formal update.
