An FBI agent says the man charged in the kidnapping of Elizabeth Smart told him that he expected the world would see him as a child predator, sexual deviant and monster.

The agent, George Dougherty, also testified during a federal court competency hearing Wednesday that Brian David Mitchell said Smart could have returned to her family anytime she wanted and was never gagged as searchers called her name.

Dougherty recounted four interviews he had with Mitchell in March 2003 after Smart was found walking a suburban street with Mitchell and his now-estranged wife.

The hearing is intended to determine if Mitchell is competent to stand trial on charges of kidnapping and unlawful transportation of a minor across state lines.
