(KNZA)--A former Jackson County volunteer firefighter charged with setting a string of grass fires will have to serve 180 days in jail as a condition of probation.

27-year-old Jacob Grant, of Mayetta, was sentenced Friday in Jackson County District Court to a total of six years probation on three counts of arson.

Grant pleaded no contest to the charges last month.  As part of a plea deal, 10 additional arson counts were dismissed.

Grant was arrested March 21st following an investigation by the Jackson County Sheriff’s Department.

Authorities say Grant set numerous grass fires between February 28th and March 20th in southwestern Jackson County, and then responded as a member of the Delia Fire Department.
