Authorities in Williamson County are investigating after a 4-year-old child apparently drowned at a Round Rock home Monday morning.

According to the Williamson County Sheriff's Office, officers responded to the home located on Monument Drive at around 10:55 a.m. When they arrived, medics were seen loading the boy into an ambulance. The boy -- identified as Alister James Hyder -- was taken to Dell Children's Medical Center of Central Texas where he was declared dead.

The sheriff's office told KVUE's Rebeca Trejo they believe the child somehow got out of the home while his mother was inside. When the mother went outside to look for him, she told authorities she saw him at the bottom of the above-ground pool at the house.

The sheriff's office is investigating the death alongside Child Protective Services and will provide more details as they become available.They told Trejo that there are no pending charges currently and that the death may have been accidental.

Drowning is the number one cause of death for children under 5-years-old in Texas.

In 2016, 107 children under 17-years-old died from drowning, according to the Department of Family and Protective Services.

The agency has several suggestions to keep your kids safe, including:

  • Put up fences with self-closing and latching gates.
  • Use alarms. There are alarms for back doors and for the water's surface.
  • Store water toys away from the water when not in use so they don't attract a small child.
  • Responsible adults should constantly watch children in any body of water from an ocean to a bathtub to the standing water on a pool cover.

The owner of Round Rock Pool Pros has two children, ages 3 and 5.

He just installed his own pool and hopes his safety message will stick.

"Just explain to the kids you don't go out the door without an adult ever," Pinson explained. "And we watch them just to make sure. You know, that's the huge thing with kids you want the responsible adult out there at all times."

Pinson also recommends installing drain covers in your pool. The suction at the bottom of a pool can be deadly.

His company will not work on a pool that does not have those covers, because of the danger.
