According to his arrest warrant, Matthews used his debit card and ID to purchase a gas can, a 10-pack of automotive shop towels and a lighter on or around 25 March. Days later, the Greater Union Baptist Church and Mount Pleasant Baptist Church in Opelousas were burned.
The document also says Global Positioning System tracking through cellphone tower data shows Matthews was in the area of all three church fires.
Holden Matthews, 21, was arrested and charged with three counts of simple arson of a religious building. The affidavit said a Ford pickup like the one Matthews was driving was registered to the suspect's father, Roy. Matthews' cell phone was traced to the area of the fires.

Harry Richard - pastor of Greater Union Baptist Church, the site of the second fire - said he's relieved about the arrest. Perhaps the most infamous was the Ku Klux Klan bombing of the 16th Street Baptist Church in Birmingham, Alabama, in 1963.
