A male toddler was in critical condition late Sunday after being pulled from the bottom of a Gwinnett County swimming pool while his father grilled nearby.

Firefighters were called around 8:30 p.m. to the Menlo Creek apartments in the 4300 block of Satellite Boulevard near Duluth, where they found a woman performing CPR on the child, according to Capt. Eric Eberly with the Gwinnett fire department.

A 15-year-old girl at the pool spotted the boy, Jaiden Carnes of Marietta, floating and unresponsive, according to the police report obtained by the AJC. The teen called her father over, who pulled Jaiden out of the water, she told police. Another witness began performing CPR on Jaiden, who turns 2 on June 28.

Jaiden's father, Brian Carnes, also of Marietta, told police he was at the grill when he heard someone shout, "Whose child is this?" according to the report. Brian Carnes told police he thought his son was standing beside him at the time.

Paramedics arrived and continued life-saving efforts on the child, who was transported to Gwinnett Medical Center in critical condition, Eberly said. From there, Jaiden was flown to Children's Healthcare of Atlanta for treatment, according to police.

The incident remained under investigation Monday, police said.

The near-drowning in Gwinnett County occurred one week after two 5-year-old girls drowned in a backyard swimming pool in Paulding County.
