Alabama ? Three former college students accused of setting a string of church fires last year pleaded guilty to state arson and burglary charges Thursday, three days after they were sentenced on related federal counts.

Matthew Cloyd, 21, Benjamin Moseley, 20, and Russell Lee DeBusk Jr., 20, were sentenced to two years each in state prison, to be served after their federal sentences.

Cloyd and Moseley each face eight years in federal prison. DeBusk was involved in only some of the fires and was sentenced by a federal judge Monday to seven years.

Their round of pleas Thursday resolve state charges in only five of the church fires: those in Bibb County, about 45 miles south of Birmingham, that were started Feb. 3, 2006. The defendants still face charges related to four other fires a few days later in three counties near the Mississippi line.

All three former Birmingham-Southern College students pleaded guilty to state arson and burglary charges.
