A 74-year-old and two of his great-grandchildren were killed in a crash during their road trip from South Carolina, news outlets in Arizona reported.
The Arizona Department of Public Safety said four other relatives were injured when the family’s pickup truck crossed into a median and flipped along Interstate 10, according to KPNX.
Troopers told news outlets the crash happened at about 4 a.m. on Nov. 23. The incident was near State Route 387 in the Casa Grande area, roughly 40 miles southeast of Phoenix.
Officials told KTVK that 74-year-old John Henry White was driving the family of seven in a pickup truck when he overcorrected, leading to a rollover.
White and two other family members died at the crash site: his 3-year-old and 9-month-old great-grandchildren, the Arizona Republic reported.
The crash sent four other relatives to a hospital with serious injuries. They were identified in news reports as the 33-year-old mother of the deceased children as well as her other kids, ages 13 to 9 months. The two babies were twins.
Officials told KSAZ the family was on a road trip from North Charleston, South Carolina, about 2,100 miles away. Troopers believe fatigue may have played a role in the crash.
The crash closed part of I-10 for hours before lanes reopened. The incident was under investigation as of Nov. 28, according to KSAZ.
The Arizona Department of Public Safety didn’t immediately share additional information with McClatchy News on Nov. 30.
