Police say a 21-month-old boy drowned Wednesday after climbing into an above-ground pool in the backyard of his family's East Islip home on Long Island.

Authorities were called to the home on Laurel Ave around 12:40 p.m. after a family member found Byron McArthur at the bottom of the pool. Police said the child had climbed a ladder to get into the pool. He was taken to Southside Hospital, where he was pronounced dead.

A 4-year-old boy was pulled from a pool at a Queens home Wednesday evening around 6 p.m.
