UPDATED STORY:'God always takes the special ones': Community mourns after Sebastian student's sudden death

AUTOPSY RESULTS:Kamaree Lyons, Sebastian student-athlete who suddenly died, had 'abnormalities of the heart'

Kamaree Jevon Lyons, a 17-year-old Sebastian River High senior and football player, died Saturday night after a school basketball event.

He was playing basketball at the high school during open gym Saturday night, said Indian River County School District spokeswoman Cristen Maddux.

"He walked off the court and collapsed," Maddux said. "An ambulance transported him to Sebastian River Medical Center and, unfortunately, he passed away."

Kamaree also attended the Gifford Youth Achievement Center since he was in kindergarten or first grade, said Angelia Perry, the center's executive director.

“He was such a wonderful young man,” Perry said. “He had a beautiful smile, a beautiful spirit, was a good student and when he saw you, he had to give you a hug. … We were expecting great things from him.”

Perry said Kamaree's mother passed away about three years ago and his older sister, Ebony Hart, helped raise him. The center awarded her with a parent award, Perry said.

“He’s just been a part of our family for GYAC," she said. "We mourn with his birth family. That family has just been hit hard recently."

Perry said his mother's death was unexpected and that Kamaree's uncle was Garry Chambliss, the Indian River County Sheriff's Office deputy, who was killed in a February 2017 shooting. The veteran law enforcement officer was off duty at the time of the shooting.

Maddux said grief counselors will be at the high school Monday for students and teachers and will stay as long as needed.

Former Sebastian River High football coach Chuck Kenyon had Kamaree in weight lifting class last school year and called him a “good all-around kid.”

“He was always respectful,” said Kenyon, who is now an assistant football coach at Veterans High School in Kathleen, Georgia. “I never had a teacher email me and say that he was being a problem.”

Sebastian River High football coach Tyrone Perry said the team will not be practicing Monday and that about 40 players met Sunday at Woody's.

“We’ll meet as a team and go from there," Perry said of meeting with the team Monday. "I just want them to know that we're there for them. I just want to make sure the kids are OK.”

This was Kamaree's first season playing varsity football and he played fullback and on special teams.

“I just feel numb. He was a great kid, he was always smiling," Perry said. "He just got a chance to play Friday night.”

Kamaree is the second Sebastian River High football player to pass away in the past four years. In August 2014, William Shogran Jr., 14, died from heat stroke during a team practice.

The Indian River County Sheriff's Office has an active investigation to determine what happened, according to Maj. Eric Flowers, the sheriff's office spokesman.
