another reporter covering the case:
The state calls the next witness, Ray Yeager, previously employed with Cobb County police.
Yeager was previously employed with the Cobb police high-tech crime squad, which did forensic analysis of digital devices. His background includes extensive work both in IT and law enforcement. He is now retired and works as a part-time reserve officer.
Yeager says on June 19, 2014, he was assigned the task of analyzing the numerous digital devices that belonged to the Harrises.
Yeager describes how he analyzes the data on cellphones and computers, which take more time to examine because there is more memory space. Investigators use a program called Cellebrite to extract information from mobile devices.
As the various devices were brought to Yeager, they were cataloged. But before he could examine the device's contents, he must have a search warrant for each specific device.
Yeager said one of the last people Ross Harris communicated with was a contact in his cellphone named Angie Kay, or Dark Phoenix 1982.
Numerous devices were searched, including a laptop belonging to Leanna Harris. Yeager said he copied the entire hard drive, and the copy was used for analysis.
An external hard drive was the next device Yeager searched. He received the device July 8.
Yeager was given a work laptop belonging to Ross Harris on June 20. Five days later, he was unable to get a code from Home Depot to unencrypt the computer so he could access the data.
On June 26, Yeager found five URLs to the Reddit website, where the search included the phrase "childfree."
During cross-examination, Yeager says he probably didn't look at every file on each device due to the number of them. Two phones, a tablet, 4 laptops and other storage devices with a total of 1.5 terabytes were examined.
Yeager says he found no evidence that files were hidden or modified to avoid behind found on the electronic devices.
Yeager says there were 32 search warrants in the case, and he did not read through all of them.
Defense attorney Carlos Rodriguez tells Yeager his report to detectives didn't provide all of the videos from Ross Harris's phone.
