ATLANTA — A judge denied bail on Thursday for a suburban Atlanta man who prosecutors said intentionally left his 22-month-old son strapped inside a hot car to die because he wanted to live a child-free life.

The judge also found probable cause for murder and child cruelty charges against Justin Ross Harris, 33, of Marietta, Georgia, after hearing evidence that he exchanged nude photographs with women other than his wife while he was at work and his son was dying in the car on June 18.

The lead detective in the case testified Harris was having marital and work problems and had done Internet research on living child-free and how to survive in prison before leaving son Cooper Harris in their sport utility vehicle for seven hours.

“We believe the evidence has shown that this was intentional,” said Assistant District Attorney Chuck Boring.

Defense attorney Maddox Kilgore accused prosecutors of trying to publicly shame Harris with tawdry evidence and said there was no proof that he knowingly left his child in the car on a day when the temperature in Atlanta was in the 90s.

Harris told police he forgot to drop his son off at day care before heading to work the morning of June 18.
