According to detective testimony at the probable cause hearing this morning, Justin Ross Harris, the Georgia father whose 22-month-old son Cooper died from hyperthermia in his SUV, was sending graphic text messages to a woman and a teenager in the hours before his son was found dead.

ABC News reports that during the probable cause hearing, prosecutors testified that Harris' behavior indicates his state of mind at the time of Cooper's death.

Detectives also testified that the defendant wanted to live a "child-free life." Testimony claims that Harris was not cooperative with detectives when they asked him to get off of his phone call at the crime scene, and when he was charged with Cooper's murder, Harris responded that there was "no malicious intent."

During the probable cause hearing, Detective Phil Stoddard described Coopers death as "extremely painful," as the child would have endured high temperatures for a long duration of time in order to have succumbed to the conditions.

Stoddard also recalled Harris' statements made to his wife following the child's death, in which he said that Cooper looked "peaceful" and that "his eyes and his mouth were closed," a fact which was disputed by the detective.

Stoddard also stated that the police detectives have photographs that show Cooper's eyes were not closed, and that Harris' search history was much more extensive than previously reported, and "included a child free website and how to survive in prison."

Those searches are in addition to the previously disclosed searches about animals and children dying in hot cars.
