The body of Brandon Smith, 17, was found in a wooded area less than one mile from the local police station on Saturday, two days after he failed to return home, his grandparents told 11 Alive News.

“I’m not gonna rest until they catch the killer who killed my grandson,” said his grandmother, Maxine Smith, who raised the teen since he was an infant.

She said she first became concerned when the athlete, who dreamed of playing in the NFL, failed to return home Thursday night.

“I woke up Friday morning and I knew he was gone,” she said.

“So I’m up, kept calling his cellphone, couldn’t find him, couldn’t find him, so I called the school.”

Smith was reported missing shortly after, and on Saturday Manchester High School football coach Stephen Holmes gave the bad news to his family.

His body was found a day before his team played the Georgia 1-A State Football Championship on Sunday. His teammates held up his No. 52 jersey as they walked onto the field.

Manchester Police Chief Gray Couch said his department received a call from someone “reporting what they believed to be a dead person behind a residence.

“My officers responded to the location to find a black male with no signs of life behind a residence in a thick, wooded area,” he told Newsweek.

“Because foul play is suspected, the Georgia Bureau of Investigation was called in and is taking the lead in the investigation.”

So far, no suspects have been arrested, 11 Alive News said.

“His game, all his teammates — football was his everything,” his grieving grandma told 11 Alive.

“And he wanted to make it, but his life was cut short.”

“His game, all his teammates — football was his everything,” his grieving grandma told 11 Alive.

The teen never caused any problems before his killer “took his dream from him,” his grandfather told WTVM.

Following Brandon’s death, Meriwether Schools Superintendent Robert Griffin and Manchester High School principal Suze Neal wrote a letter to the community.

“We are heartbroken to hear the news of the tragic and untimely death of one of our student-athletes, Brandon Smith,” they said.

“Manchester High School’s celebration at playing for the Georgia 1-A State Football Championship has unfortunately turned into something none of us could have fathomed.”

Then, prior to the big game at the Falcon’s Mercedes Benz Stadium on Sunday, Smith’s teammates honored their fallen colleague by holding up his No. 52 jersey as they walked onto the field.

The Manchester Blue Devils lost the game by just one point, 28 – 27, but Holmes said he remained proud of what his team accomplished.

“All those people right there, our community, those people watching at home — they’re looking to us for strength tonight,” he told 11 Alive.
