Detectives in the search for missing Trenton Duckett are now poring over international airline records trying to determine whether the toddler was whisked out of the country, Local 6 News has learned.

Trenton Duckett was last seen in late August after his mother, Melinda, reported him missing from their apartment in Leesburg, Fla.

Melinda Duckett then committed suicide days later.

Now, investigators are looking into the possibility that Duckett sent her son to Korea.

"We do have certain individuals who stated that Melinda had talked about her roots and possibly sending little Trenton back to his roots," Marion County Sheriff's Office Maj. Chris Blair said. "We are working with customs and issuing some subpoenas. They are aiding us in trying to obtain information on people who were located on certain flights."

Detectives have no solid proof that the boy was shipped to Asia, the report said.

However, Marion County investigators said they believe Duckett, who was born in Korea but was adopted by a New York family when she was a baby, may have handed off her son to someone near a Belleview restaurant last year.

"We are doing a complete and thorough investigation," Blair said. "And we will be able to say when we complete this, whether we find Trenton or don't, is that we made every available effort to locate him."

Detectives are continuing to talk with people in Florida and other states concerning the case.

Anyone with information concerning the whereabouts of Trenton is urged to call Crimeline at 800-423-TIPS.
