The Associated Press is reporting that a 3-year-old Michigan boy who drowned at a northern Ohio water park was found face down in a children’s pool.

Hassan Itani, of Dearborn, was pulled from the outdoor pool at Kalahari Resorts water park in Sandusky, Ohio and taken Sunday afternoon to a hospital, where he was pronounced dead.

Capt. Paul Sigsworth of the Erie County Sheriff’s office called the death a “tragic accident.” Coroner Brian Baxter said the mother momentarily lost sight of her son, who didn’t know how to swim and was playing with an older brother around the pool, which ranges from 3- to 4-feet in depth.

Kalahari spokeswoman Carrie Leum said in a statement that park employees were “deeply saddened” by the toddler’s death. She says the park is cooperating with law enforcement.
