Update: Boy who drowned in Maple Grove pool was 14 months old

He was found unconscious in a pool.

The boy who died after being found unconscious in a pool over the weekend was 14 months old.

Gavin Dennison died of drowning, the Hennepin County Medical Examiner ruled Wednesday. The office lists it as an accident. Maple Grove police and the Hennepin County Sheriff's office are investigating.

Drowning is the second leading cause of unintentional injury death for children ages 1 to 14, the CDC says.

The original story from Sunday is below.

Police are investigating after a child was found unconscious in a pool at a Minnesota home.

The Hennepin County Sheriff's Office says it happened at the 7300 block of Orchid Lane in Maple Grove around 9 a.m. Sunday morning.

First responders at the scene began life saving measures. Unfortunately, the child was then taken to a nearby hospital where he was pronounced dead, the release says.

Authorities have not released information about the circumstances leading up to the drowning, or the boy's age or identity.

The Star Tribune is reporting the boy is under two years old, and that family members had tried to revive him after he fell in.

"We don't know how long the baby was under," one officer told the paper.

This is a developing story – GoMN will provide updates after the Hennepin County Medical Examiner’s Office announces the identification and official cause of death.

Two children drown every day

About ten people die from unintentional drowning every day, the Centers for Disease Control and Prevention (CDC) says.

Of those deaths, two are children aged 14 or younger. It's the second leading cause of unintentional injury death for children ages 1 to 14.

And for each child drowning death, about six more children need hospitalization or emergency-department care for near-drowning or non-fatal submersion injuries, the CDC says.

MN Water Safety Coalition says swimming pools are the most common place for a drowning to occur among children of those ages.

It can happen really fast, the Minnesota Department of Health warns. A child submerged for just two minutes will lose consciousness, and after four to six minutes, irreversible brain damage occurs.
