Four people died Saturday when a pickup truck going the wrong way on Interstate 95 collided head on with a minivan headed from New York to Florida, the Georgia State Patrol said.

The patrol said southbound lanes were closed for about four hours after the accident around 6:30 a.m. in Richmond Hill, south of Savannah.

Trooper Chris Cuddington said the pickup was headed north in the center southbound lane. The accident was under investigation, but "alcohol is going to be a factor," Cuddington said.

The truck driver, Michael Delph, 28, of Clemson, S.C., and the female driver and two men in the minivan were killed, the trooper said.

He identified them as Michelle Carryl, 41, of Apopka, Fla., and passengers Cyril Millington, 59, of Queens, N.Y., and Dwight Spencer, about 19, of Apopka.

Carryl's children, a 15-year-old boy and girls 9 and 13 were taken to Memorial Health University Medical Center in Savannah. They were expected to survive their injuries, Cuddington said.

He said Delph's mother lives in Phenix City, Ala.
