Justyn Knox Martin, who went by Knox, was found unresponsive at about 8:25 p.m. at his family’s home in Powder Springs, Cobb Police spokesman Michael Bowman said.
Brad Martin, Knox’s uncle, said his brother, Jason, and his wife, Tera, also lost another child, a 3-month-old son, to Sudden Infant Death Syndrome in 1997.
“It just compounds their loss,” Martin said, adding he also lost a daughter to SIDS.
Martin, a Cartersville resident, said his brother Jason, Tera and their six children were all celebrating Knox’s 4-year-old sibling’s birthday on Saturday.
“They had just gotten a new swimming pool,” he said.
Martin said the family swam in the above-ground pool during the day but returned inside that evening to change clothes and watch a movie together. Soon after, Martin said his sister-in-law couldn’t find her son.
“About two minutes after that, his 15-year-old brother got up to look for his brother,” Martin said. “He found him floating face down in the swimming pool.”
The 15-year-old pulled Knox — who had apparently climbed in from the pool’s portable ladder — from the water and ran inside with the boy, where Jason Martin performed CPR until the ambulance got to the home, Martin said.
Martin said his brother and sister-in-law are turning to their faith to overcome the loss and have had support from their church, The Journey Church in Hiram.
“We follow Jesus and without him I don’t know how people do this,” he said.
In lieu of flowers, Martin said the family has asked donations be made directly to the church for the care of Knox.
“Unfortunately, they didn’t have life insurance,” he said. “They are just asking that people give in lieu of that, for their expenses and time off of work.”
