CHANDLER, Ariz. -- A 3-year-old boy who was found at the bottom of a backyard pool in Chandler Sunday has died.
The toddler was at a birthday party at a house near McQueen and Chandler Heights roads.
More than 40 people were at the home, according to a spokesman for the Chandler Fire Department.
The spokesman said no one noticed the toddler until the party started winding down, and parents were coming over to pick up their children. That's when they noticed the toddler in the bottom of the pool.
They do not know how long the child was underwater, but they said two adults pulled him out right when they saw him and called 911.
The child was taken to a nearby hospital in extremely critical condition. He died Tuesday morning.
"It's very important that when you have a large gathering at your house and you're going to be swimming with children that you make someone accountable for the pool area," Tom Dwiggins with the Chandler Fire Department said Sunday. "Somebody has to be assigned to watch everybody inside the pool. You should set up some type of rotation system whether it's every 20 or 30 minutes, an adult is always watching the water. One thing that's important about that adult is that their only job is to watch the children in the pool. They're not texting. They're not talking to someone else. They're not reading a magazine. They literally have eyes on the pool at all times."
