Police are investigating a report of a 20-month-old girl found alone near a rocky coastline in Kealia on Kauai.

A couple from Anahola said they found the toddler as they were walking along Ke Ala Hele Makalae, also known as Kapaa Coastal Path, at about 10 a.m. Sunday.

Maile Freitas, 40, said she heard a baby crying and that when she looked below the path, she saw the toddler standing in a rocky area near the coastline. There were no adults with her, and the baby was wearing only a diaper, she said.

Kauai County spokeswoman Kim Tamaoka said the toddler was found in a “rocky area, approximately 300 yards north of the restrooms at Kealia Beach.”

Freitas said her boyfriend, Jace Miner, slid on his backside down a steep incline to reach the baby. While there, Miner said, he looked for the baby’s parents on both sides of the coastline. “There was nobody on the rocks. No parents on the rocks,” he said.

Freitas followed her boyfriend down the incline, and with help from a male bystander, the couple made their way back up to the coastal path with the toddler.

Once they reached the path, Freitas said, the toddler fell asleep in her arms. “She was crying and really exhausted,” she said.

Another bystander, Leiola Kamalani-Oliver, called 911.

“Everyone was in a panic,” Kamalani-Oliver said. “We all looked around for the mom and dad.”

A lifeguard on an all-terrain vehicle from Kealia Beach was first to respond. According to Miner, the lifeguard searched along the coastline and path but could not find the girl’s parents.

Medics transported the toddler to Wilcox Medical Center where she was released to the custody of Child Welfare Services. In an email statement, Tamaoka said the child “was alert and had no injuries.”

Freitas said, “I’m glad the baby is OK.”

A Facebook comment by Lauren Ray, who identified herself as the mother, explained how the child got separated from her parents. The Honolulu Star-­Advertiser could not verify the Facebook post came from the mother.

Lauren Ray’s comment said she thought the child’s father was watching the child when Ray went to a public restroom at Kealia Beach. When she came back from the restroom, she thought the father had taken the child with him.

“I should have communicated with him better. I was wrong on that,” the Facebook comment said. “I should not have assumed he knew I had not taken her with me.”

“I’m here thanking god that my baby is safe after this seriously scary situation,” the comment said.
