() Bryan Kohberger had only 18 contacts saved in his phone, according to the digital forensics experts who analyzed his devices.

Heather and Jared Barnhart, who investigated Kohberger’s phone and hard drive, told “Banfield” that some of the contacts were saved under odd names.

Kohberger’s 18 saved contacts

“He had 18 personal contacts. Eighteen,” Heather said. “Think about all the people you meet and the hundreds of random numbers, and they were even identified as ‘girl I ran with,’ ‘second girl I ran with.’ A contact then in parentheses ‘hair.’

“Then there was mother and father, and his sister and just a few others.”

‘Mother’ and ‘Father’ calls

Another detail that stood out to the Barnharts was how Kohberger had saved his parents in his phone as “Mother” and “Father.”

“It’s eerie. It stands out from any other case I’ve worked,” Jared said.

It was revealed Wednesday that Kohberger called his mother less than two hours after murdering Madison Mogen, Ethan Chapin, Xana Kernodle and Kaylee Goncalves.

He spent more than three hours on the phone with her the day of the murders. Kohberger would immediately call his father if he couldn’t reach his mother, and would constantly call and text them beginning at 5 a.m.

“And also at night, to almost talk him into going to sleep and being able to rest,” Heather said.

They said he barely communicated with anyone other than his parents. To that end, Kohberger had 18 saved contacts in his phone.

Kohberger was sentenced to life in prison and is being housed in solitary confinement outside of Boise, Idaho.

“He had 18 personal contacts,” Heather said. “And they were even identified as ‘Girl I ran with,’ ‘Second girl I ran with.’

He reportedly complained about being tormented in prison and the facility has since spoken out, saying he is safe despite inmates’ taunts.
