COBB COUNTY, Ga. – A former inmate at the Cobb County jail who spent time with Ross Harris said that the man accused of leaving his son to die in the back of his hot car showed no emotion.

Mark Wilson was booked into Cobb County Jail on a DUI on the same daythat Ross Harris was arrested.

Wilson wouldn't say much because he's under contract with the National Enquirer, but he did confirm the accuracy of the article and the quotes attributed to him.

In the National Enquirer article, Wilson says he met Ross Harris while they were both being booked into jail. Wilson says the accused killer casually chatted him up and did not act like a man who had just recently lost his son.

"There was no emotion whatsoever in his voice, attitude - anything," Wilson told the magazine. "There was just no sadness in how he was acting."

Wilson added, "I just don't see how someone, a father, could act completely normal and calm in a situation like that, especially like two, three hours after the whole thing happened. It was a little weird."

Wilson got out of jail the next day. It was only after he watched media coverage of the case that he realized who he had befriended.

Harris is being held without bond on charges of child cruelty and murder in the death of his 22-month-old son, Cooper.

Last week, Ross Harris' wife, Leanna, retained the services of attorney Lawrence Zimmerman. Sources confirm to 11Alive that Zimmerman met with Atlanta attorney Lin Wood to discuss "some of the scandalous statements made by tabloids."

Wood represented Jon and Patsy Ramsey in the JonBenet Ramsey murder case. He was Richard Jewell's libel and defamation attorney after the Olympic Park bombing.
