Trenton Duckett disappeared two years ago, when he was 2 years old.

The boy's father, Josh Duckett, showed up at the scene of the search for Caylee on Thursday.

Josh Duckett said he understands what Caylee's grandparents are going through. His son's disappearance remains a mystery.

Melinda Duckett was also young, and she reported her son missing in 2006. She said Trenton had been abducted, but evidence contradicted that claim.

Investigators became suspicious and Melinda Duckett committed suicide.

Josh Duckett commented on the investigation into Caylee's disappearance.

"If she's got the information, I wish she would just tell. I mean, because honestly, the family deserves closure, and the family deserves to know where the baby is at. I mean, no 2-year-old should have to be away from their family," Josh Duckett said.

Duckett has been active in the search for his own son consistently. He's made his voice heard and presence known during the search for Caylee Anthony.
