Eyewitness News' sister station in Atlanta spoke to Amir's aunt Denise Jennings, one of the last people to see Amir back in November.

She said she's doing everything she can to cooperate with authorities and bring Amir home.

"I can't begin to describe [how I feel]. The evenings and nights are worse for me," Denise Jennings said.

Denise Jennings is an aunt to 18-month old Amir Jennings. He hasn't been seen in six weeks.

Amir and his mother, Zinah Jennings, used to live with Denise at her home near Atlanta. But she said they left without warning a few days before Thanksgiving.

"She left with Amir. It was evening. It was cool out. And she walked out with him," Denise Jennings said. "We love him. And we want him home."

Both Denise and Amir's grandmother Joyce Jennings say Zinah has been battling post-partum depression.

Police arrested Zinah at the end of December. Investigators said she told them lie after lie about what happened to her son.

Police have searched from Charlotte to Atlanta for the little boy.

Amir's father used to live in Charlotte, and Columbia police said the Charlotte-Mecklenburg police department is helping them in the investigation.

Denise believes Amir is alive and well.

"I think that [Zinah] left him with someone. I think she was scared and wanted him to be cared for," she said.

On Thursday, Columbia police officers and federal agents searched Denise's property with cadaver dogs.

"They came and explained what they were going to do. I was glad to see them," she said.

It's at least the second time investigators have used cadaver dogs.

On Wednesday, Columbia police officers searched Joyce Jenning's property with a cadaver dog. Zinah and Amir had recently lived there.

Zinah Hennings is in jail on a $150,000 bond. She faces a child cruelty charge for refusing to tell investigators what happened to her son.
