State police Capt. Jimmy Glascock says 40-year-old Guillermo Montes of Bovina, Texas, was thrown out of the vehicle Saturday night when it went off a highway and rolled over, coming to rest in a field in Curry County.
Glascock says little Elizabeth Kazza realized her father was dead and drove for about three miles until a passing motorist spotted her.
"(It took) a lot of courage. ... It's remarkable anybody could drive after something like that," Glascock said.
Authorities found Montes dead at the scene. The girl and her 4-year-old brother were treated for minor injuries.
State police said Wednesday that Elizabeth told officers her dad was driving to Clovis, about 25 miles from Bovina, to get beer when they crashed.
They said alcohol was believed to be a factor in the crash. Glascock said beer bottles were found at the scene, and that Elizabeth and her younger brother said Montes was drinking as he drove.
