VALDOSTA, Ga. -

Georgia State Patrol officials say four people were killed in a series of crashes on a stretch of Interstate 75 near Valdosta.

The Valdosta Daily Times reports troopers were responding to one crash involving two vehicles Sunday night when a tractor-trailer sparked a second crash that involved eight vehicles.

"There was three semis involved, one U-Haul, one F-250 with a camper and three other vehicles," Cpl. Peter Lukas with the Georgia State Patrol in Valdosta told WALB-TV.

Authorities say a Florida man, a Tennessee couple and their 3-year-old granddaughter were killed in the second crash.

Troopers say a vehicle in one of the freeway's southbound lanes blew a tire and the driver lost control, hit the median and was hit by another car. Authorities say a 21-year-old Tallahassee, Florida man and six people from Jacksonville, Florida were hospitalized in that crash.

The southbound lanes of I-75 remained closed for several hours.

Lukas said the driver of the semi could face charges, pending the accident investigation, but it could be months before that investigation is complete.
