Coroner Jay Jones identified the toddler as Easton Dildy of County Road 249 in the Glen area.
Jones said it appears the child, along with his twin, got outside the home through a garage door that was partially open. They then went behind the house to the pool, where the child apparently climbed to the top of the ladder and went into the water.
The discovery of the child in the swimming pool at the residence was reported to 911 at 10:04 a.m.
The child was taken to Magnolia Regional Health Center.
Memorial Funeral Home will have the funeral arrangements.
