GEARHART — A 3-year-old boy drowned in a neighbor’s pool Tuesday evening.

Authorities said Grayson Bishop was playing outside with his 5-year-old brother under the eyes of adults, who suddenly realized the younger boy was missing.

The adults started looking for Bishop. A short time later, his grandmother found him in the neighbor’s above-ground pool. A fence that separates the properties had a small opening that the boy had slipped through.

Bishop was taken to Columbia Memorial Hospital in Astoria but did not survive.

“It’s one of those tragedies that absolutely breaks everyone’s heart, you know?” Sheriff Matt Phillips said. “It just really doesn’t get a lot worse, if at all.”

The family has set up a GoFundMe account to help pay for funeral and medical expenses.
