Holden Matthews, 21, has been booked into the St. Landry Parish jail on suspicion of arson, KATC-TV reported, citing law enforcement sources. Matthews is the son of St. Landry Parish Deputy Roy Matthews. Authorities have not released a mug shot of the suspect.

The first fire took place last month at the St. Mary Baptist Church in Port Barre on March 26. The second happened April 2 at the Greater Union Baptist Church in Opelousas, while the latest came two days later at the Mount Pleasant Baptist Church, also in Opelousas.
