According to Goliad County officials, a white 2000 Ford F-250 pickup truck packed with passengers slammed into two large trees outside of Corpus Christi. The cause of the crash was under investigation.
Twenty-three people were loaded inside the truck's cab and bed. The truck was heading north on U.S. 59 when it went off the right side of the highway. Six of those killed were still inside the truck when emergency crews arrived. Officials said several of the survivors were airlifted to hospitals with life-threatening injuries.
Gerald Bryant, a spokesman for the Texas Department of Public Safety, told ABC News that U.S. Border Patrol was assisting with the investigation. The legal statuses of the victims were not immediately known, Bryant said.
