Kyron Horman's Mom Pleads for More Reward Money

An emotional Desiree Young told a Friday news conference she hopes the $50,000 reward for finding Kyron Horman, who would be 8 now and was 7 when he vanished, can be upped to $350,000. That's the amount Kyron's stepmother, Terri Horman, has reportedly paid a Portland defense attorney.

Young says she is confident Kyron, who would be 8 now and was 7 when he vanished, is still alive and says, "There is someone out there that has him."

"I don't know what else to do," she said, choking up. "It's been four months now, and Kyron is still not home."

"We want Kyron home and we want him home right now," she continued, "and I want someone in Terri's circle to come forward with information."

"Money is a motivator," she added, "and if that's what it takes, then that's what it takes. I want my son home. This is unacceptable."

Kyron has been missing since June 4, when he disappeared after a science fair at his elementary school. Exhaustive searches followed.

Terri Horman has not been charged with a crime, but the investigation into Kyron's disappearance has centered around her. She was the last person known to have seen him. She says she left him at the science fair.

Both she and her defense lawyer have repeatedly declined to comment.

But both Young and Kyron's father, Kaine Horman, have said they believe Terri Horman is involved in Kyron's disappearance, notes "Early Show" national correspondent Hattie Kauffman.
