Wearing only a diaper, an 8-month-old baby was spotted floating in New York's East River, but even though the infant was rushed to the hospital, he was pronounced dead. The medical examiner will determine how he died.
Police say the child showed no signs of trauma.
Tourists from Oklahoma had seen the boy around 4 p.m. and Monte Campbell went into the water to get him out, his wife said.
A family of tourists from Oklahoma had just finished a Statute of Liberty tour in Lower Manhattan when they saw what they at first thought may have been a doll in the East River. "My mom, she was out here and she was kind of just looking in the water, and she calls my dad over and says, 'There's a baby in the water!'".
"There was no pulse, no respiration", Campbell, a chiropractor, said.
Unsure if someone else had gone in with the baby, rescue crews continued to search the water Sunday night.
The baby's parents were not on scene.
Diana Campbell posted a news story about the incident on her Facebook, adding, "Asking for prayers for this handsome baby boy. someone out there knows what might have happen to him".
"Someone knows that child", she told the Times.
He and police officers called to the scene gave the baby CPR until an ambulance arrived, NY media reported.
He waded into the water and used a stick to help him grab the baby, then performed CPR until officers arrived on scene, Campbell said.
