Two adults and three children from Porter died after their SUV left an Interstate 10 overpass and landed on FM 725.
SEGUIN, TX — Five members of a Houston-area family, including three children, were killed Sunday when their SUV left eastbound Interstate 10, went off an overpass and crashed onto Farm-to-Market Road 725 below, authorities said.
The Seguin Police Department said the single-vehicle crash happened shortly before 1 p.m. Nov. 8. The family was traveling east in a black Chevrolet Tahoe when the vehicle left the highway near FM 725. Police said all five people in the SUV died. No other vehicles were reported to have been involved.
Authorities identified the adults Monday as Omar Lumbreras Oliva, 30, and Ana Deli Lumbreras, 31, both of Porter, a community in Montgomery County northeast of Houston. The other victims were a 13-year-old boy, a 6-year-old girl and a 3-year-old girl. Seguin police did not publicly identify the children by name in its initial release.
Police said rain was falling when the crash occurred and the roadway was wet. Investigators have not determined what caused the Tahoe to leave the interstate, and officials have not announced a final finding on whether weather or road conditions contributed to the crash.
The crash forced authorities to close the affected roadway for several hours while police, firefighters and other emergency personnel worked at the scene. The City of Seguin said the roadway reopened shortly after 6 p.m. Sunday.
The deaths drew attention across the Houston area after officials confirmed the victims were from Porter. Later reports identified the five victims as members of the same family. Authorities have released few additional details about their trip or the moments immediately before the Tahoe left the highway.
Investigators have not announced evidence that another vehicle was involved, and no criminal allegations have been made in connection with the crash. Officials also have not released a final crash reconstruction or other findings explaining why the SUV went over the overpass.
The Seguin Police Department continues to investigate the crash. As of Monday, authorities had not announced a final cause or a timetable for completing the investigation.
