Four El Pasoans were killed in a rollover on Interstate 10, about 30 miles east of Fort Stockton Sunday morning.
Texas Department of Public Safety investigators said a rear tire on a 2006 Ford Expedition driven by 36-year-old Stephanie Ann Garza blew out.
The blowout sent the SUV into the median and caused it to roll over several times.
The crash killed her along with Taylor Garza, 18, Peter James Garza, 14 and Jessie Garza, 11.
Peter William Garza, 38, and Samantha Garza, 6, were injured and taken to area hospitals for treatment.
No other vehicles were involved.
