A volunteer firefighter from eastern Missouri has been sentenced to 20 years in prison for setting several fires last year.

Police say Dustin Matthew Grigsby was sentenced for setting four fires in occupied buildings last year in Lincoln County, although he admitted to setting several other fires. He was a volunteer with the Old Monroe Fire Protection District.

The St. Louis Post-Dispatch reports that in one case a man had to be rescued after his home was set on fire.

Grigsby was arrested last August after a surveillance camera recorded his vehicle just before a garage caught fire. He pleaded guilty in April to four counts of arson.

Grigsby in April entered guilty pleas on the four counts. Five other counts were dismissed in a plea deal.
