(CNN) -- A church van rolled over in southwest Georgia Sunday evening, killing four of the 17 occupants on board, authorities said.
The van, belonging to the Tabernacle of Prayer and Deliverance in Columbus, was headed to Florida when it overturned on a highway in Early County.
An initial investigation by Georgia state troopers indicated that the driver lost control after the van blew a tire, said agency spokesman Gordy Wright.
In addition to the four deaths, 13 people in the van were injured, Wright said. Several of the passengers were ejected from the vehicle, he said.
It was not immediately known if the occupants were wearing seat belts.
