Tison Marks, 16, killed in car accident on Dog Branch Road on May 28.

A 16-year-old Giles County student was killed driving home from a friend's house Wednesday afternoon, according to officials.

Tison Marks, a junior-to-be at Giles County High School, was killed sometime after 4 p.m. after he wrecked his truck on Dog Branch Road. The Tennessee Highway Patrol said Marks' truck went down an embankment and struck a tree.

"You hear the specific name and you start putting face, memories, family and everything with that and it's devastating," said Giles County High Principal Mark Cardin.

According to the principal, Marks got good grades and was a standout athlete on the Bobcats' football team.

Marks was the big kid that everyone loved.

"I never worked with anybody more quality than Tison Marks," said Cardin. "He was a positive role model, always smiling, a gentle giant."

Marks had been swimming and playing golf all day with his friends. He left a friend's house around 4 p.m.

His best friend found his wrecked truck along Dog Branch Road about 8 p.m.

Police believe speed and weather may have been a cause of the wreck.
