Investigators in the search for missing 2-year-old Trenton Duckett named a person of interest Wednesday who apparently had cell phone contact with the boy's mother the day the child vanished, according to Local 6 News.

Detectives with the Marion County Sheriff's Office said a man named Chai Chin, who works in Ocala, Fla., was named a person of interest in the case.

"(Sheriff's officials) tell us that this is more than just a person they want to interview," Local 6's Mike DeForest. "Again, (he is) not a suspect."

Authorities said Chin and Trenton's mother, Melinda Duckett, spent time with each other before the boy vanished.

Police said Chin was being cooperative with them during questioning Wednesday night.

Recently, new information from employees at a Wendy's restaurant in Belleview, Fla., sparked a renewed search for the boy.

Marion County sheriff's deputies said two witnesses placed Trenton's mother at the fast-food restaurant at the time of Trenton's disappearance, according to a police report.

Information that the boy vanished within a 20 minute period near the restaurant has led investigators to believe Duckett gave her son away to someone else before she committed suicide.

Belleview is 20 miles northwest of Leesburg, where Trenton lived with his mother and her grandparents.
