MASSILLON, Ohio– A student at Perry High School in Stark County passed away unexpectedly on Thursday.

Mitchell Williams was on the first day of his new job, working for a landscaping company. Tuscarawas County Sheriff Orvis Campbell said the 18-year-old was mowing at a property on King Road in Bucks Township.

Co-workers called 911 several times, but were unable to hear the dispatcher because of poor cell service, the sheriff said. Paramedics arrived and pronounced the teen dead at the scene.

The Tuscarawas County Coroner’s Office will determine the cause of death. According to Campbell, Williams temperature was very high.

Details on funeral arrangements for Williams, who just finished his junior year, are not available at this time.

Counselors will be at the Perry High School library on Monday from 9 a.m. to noon for students.
