Maines said until he could talk to his client more next week, he was going by what he had heard about Phillip's control over her.
"But there's some things that make me curious," Maines told "GMA." He noted that Nancy met Phillip while visiting a relative in prison and got married while he was still in prison.
"The fact that when he walked into the parole office, she went placidly along. And later I'm told that when the officers asked if they could search her home, she said, whatever Phillip wants. If Phillip says it's OK, it's OK," Maines said.
The lawyer also noted that Nancy Garrido did not have a job for at least the last 10 years but stayed home and took care of his mother.
"Phillip's brother apparently had described her as a robot ... and did whatever Phillip wants," Maines said. "Until I see evidence -- unfortunately we have to go on the basis of evidence and not speculation. The people cannot convict with speculation, and I can't defend with it."
