Talbot had planned to board a Delta Air Lines flight to the US with the baby, airport officials said.

"There was really an intention to hide the baby," immigration official Grifton Medina said.

After discovering the baby, airline staff called immigration personnel, who arrested Talbot at the airport. She was later handed over to the National Bureau of Investigation and the baby was turned over to government welfare personnel.

Public records indicate Talbot woman has been living in Utah.

Philippines officials previously said Talbot was from Ohio, and records indicate she has family connections there. Authorities in the Philippines said a woman wanted to offer her baby for adoption, but it was not clear that had legally took place.

Property records also show Talbot owns a home in a suburb of Salt Lake City, and got a traffic citation there in March.

People answering the door in Sandy, Utah, declined to comment.

The NBI said Talbot presented an affidavit at the airport, allegedly from the baby's mother, identified as Maricris Dulap, giving consent for the baby to travel to the US, but it had not been signed by the mother.

Officials said no government travel approval had been issued for the baby, prompting them to file human trafficking charges against Talbot. The charges carry a maximum penalty of life imprisonment. Talbot also violated at least two other laws on child abuse, kidnapping and illegal detention, the NBI said.

US Embassy officials were notified of Talbot's arrest and told Philippine authorities that she had no criminal record in the US, NBI official Manuel Dimaano said.

Dimaano said Dulap gave her baby to Talbot in southern Davao city. He said investigators will try to determine how Talbot brought the baby out of Davao, which requires a city clearance for infants to be transported by a foreigner.

The baby's parents have been charged under a child protection law but have not been placed under arrest, although the mother has been interviewed by social welfare officers, Dimaano said.

He said Dulap told the officers that she wanted to offer her baby for adoption, and there was no indication that she had sold the baby.

Dimaano said when he and other officials asked Talbot what she intended to do with the baby, she replied that she just wanted to give it "a name and a church blessing."
