Two carloads of people who lived next door to each other collided head-on on a rural highway 20 miles from home, killing six people, two of them children.
The driver of one of the cars was arrested on suspicion of drunken driving.
The dead included a couple and their infant daughter, and the woman’s sister-in-law and her daughter.
The accident occurred late Friday near Humphrey, north of the victims’ homes in Columbus.
Investigators said a car crossed the highway’s center line into the path of a station wagon carrying eight people. Five of those in the station wagon were killed, along with a passenger in the car.
The car’s driver, Armando Hernandez, was arrested at the scene. He was hospitalized with a broken hip.
