Justin Ross Harris was charged with felony murder and cruelty to children after Cobb police say he left his 22-month-old son in his car for about seven hours June 18, when temperatures reached the 90s.
Warrants released previously showed Harris admitted to researching child deaths inside vehicles and what temperature it needs to be for that to occur. New warrants say his wife, who has not been charged, performed similar research.
“Leanna Harris, the child’s mother, was also questioned regarding the incident and made similar statements regarding researching in car deaths and how it occurs,” the warrants read.
Police would not say why Leanna Harris wasn’t charged or if she was ever considered a suspect.
“The wife was questioned by detectives when this incident occurred and as you know this investigation is still active and ongoing,” said Cobb police spokesman Mike Bowman when asked about Leanna Harris’ role in the case.
The warrants show police searched an iPhone, a Dell computer, a Google Chromecast device, a Lenova T530 ThinkPad, an Apple MacBook and an iPad from Justin Ross Harris’ office, home and his 2011 Hyundai Tucson.
In a description of the crime scene, the warrants read, “It was obvious that the child was deceased.”
Justin Harris said he was supposed to drop his son off at day care that morning, but he didn’t. He did stop at a Chick-fil-A in Vinings with his son near The Home Depot headquarters, where he worked as a Web developer for the company, according to the search warrants.
Cooper Harris was left in the car from 9:30 a.m. to 4:20 p.m., the warrant says, when his father discovered he was dead while driving to meet friends.
“Justin stated that he was fearful that this could happen,” the warrant stated.
Justin Harris, 33, has been in jail without bond since that day, and his next court appearance is scheduled for July 3.
Police also looked for trace evidence, such as fingerprints, blood, DNA, hairs or fibers in his car, as well as “paperwork or writings related to the crime of homicide and cruelty to children,” according to the warrant.
