Harris told police he was supposed to drive his son to day care June 18 but went to work without realizing Cooper was in a car seat in the back.

When Stoddard told him they were charging him, Harris allegedly responded by saying, "But there's no malicious intent."

Detective: His statements were 'all about him'

Harris became emotional when his wife arrived at the police station, according to the prosecution.

"It was all about him: 'I can't believe this is happening to me. Why am I being punished for this?' It was all very one-sided," Stoddard said. "He talked about losing his job. ... 'What are we going to do? I'll be charged with a felony.' "

Leanna Harris later asked her husband, "Did you say too much?" he said.

He has worked for Home Depot for two years

Harris, 33, a Web developer, has worked at Home Depot for two years, according to the Atlanta-based home improvement company.

Home Depot placed him on unpaid leave after the charges were filed.

Stoddard said Harris would take Cooper to day care in the mornings. The couple would split picking the boy up in the afternoons. When Leanna Harris went to pick up Cooper from day care that day, the center told her he was never dropped off. On her way out, she told witnesses: "Ross must have left him in the car. ... There's no other explanation. Ross must have left him in the car," Stoddard said.

He once lived in Alabama

Harris worked at the University of Alabama as a parking monitor and later as a mail delivery clerk between 2001 and 2006, the university said.

Afterward, he was a police dispatcher in Tuscaloosa, Alabama, until 2009, according to Tuscaloosa police spokesman Sgt. Brent Blankley. The department only confirmed his tenure, not details on his work history.

Three years later, Harris graduated from the University of Alabama with a bachelor's degree in commerce and business administration. From there, he went to Home Depot.
