(CNN) Federal investigators suspect lightning may have caused the fire at Mount Zion African Methodist Episcopal Church in Greeleyville, South Carolina, senior officials in the FBI said Wednesday morning. The FBI has been working with the National Weather Service to determine whether the heavy storms in the area contributed to the fire. A forensics report of lightning strikes by CNN meteorologists shows four strikes occurred in the immediate vicinity of the church, all at 7:18 p.m. ET Tuesday night.
The officials said investigators found no accelerants at the fire scene — an indicator of arson.
The Greeleyville fire drew attention because at least five other black church fires have occurred since the racist killings of nine people in a Charleston church.
The Greeleyville church has burned before. In 1995, two members of the Ku Klux Klan set fire to its original structure.
