Unassuming hero Charles Ramsey, who helped to rescue Amanda Berry, may be eligible for reward money for his actions.

The FBI said it was offering " a reward of up to $25,000 for information regarding the disappearance of Amanda Berry," according to its website. The agency also said it was offering an undisclosed reward for information leading to the recovery of Georgina DeJesus.

Meanwhile, Ramsey said he never believed his neighbor, Ariel Castro, was capable of abducting and imprisoning three women for a decade.

"Either I'm that stupid, or [the suspect is] that good," he told George Stephanopoulos in an interview on "Good Morning America."

Ramsey said he was rendered "speechless" by the fact that his actions helped to free three women from Castro's home. But he never suspected anything strange about his neighbor, he said.

"I give this dude his mail when it comes to my house. I eat his food when he feels like barbequing. When he feels like playing salsa music, I try to meringue," Ramsey said. "Had I known [he kidnapped the women], well, this would be a whole different interview, wouldn't it?"

Ramsey was inside his house eating a McDonald's meal when the woman across the street began kicking at the door and screaming for help. Ramsey went across the street and helped kick in the aluminum screen door through which Berry and her daughter escaped.

Ramsey said the first thing Berry told him was that there were more women inside the house.

"I was just blown away from that statement," he said. "When the police got there, they went [up in the house] and brought the rest of them out."

Ramsey said there was nothing about Castro's behavior that would indicate he had allegedly kidnapped Gina DeJesus, Amanda Berry and Michele Knight, and was holding them captive.

Despite neighbors who have come forward and said they saw women crawling naked in Castro's backyard or a woman in an upstairs window holding a baby, Ramsey said he had not seen "one iota."

"I didn't see anything," he said. "She's been right there next door to me for a year."

While Ramsey said he doesn't think his actions were heroic, he said, "if people are happy, I'm happy."

"There is no feeling," he said. "You do what you have to do."
