Through a statement read in court by friend Emily Alandt, one of the surviving roommates, Bethany Funke, said she's still scared to go out in public but forces herself to do so because she knows her friends would want her to live her life to the fullest.

Funke recounted her memories of her friends at their off-campus home.

"Our house was not just a house, it was a home,” Funke said.

She said Xana Kerndole was the life of the party and “kindest and funniest person,” and that Ethan Chapin and Kerndole “were absolute soulmates."

Kaylee Goncalves “had the most beautiful, radiant smile” and could have ruled the world, she said.

Maddie Mogen, Funke’s big sister in their sorority, was the “older sister I would’ve always wanted. There was no one I looked up to or admired more than Maddie.”

“I wish more than anything I could hug them one last time,” she said.

“I still tell them every night I will keep living for them,” she said.

Friend Emily Alandt read a statement on behalf of Bethany Funke, one of the surviving roommates, describing how she woke up to her "worst nightmare."

"Never in a million years would I have thought that something like this would have happened to our closest friends,” Alandt read in court.

Funke said she didn’t know what happened that morning and carries regret and guilt over not calling 911 right away.

"I was so frantic that morning and scared to death not knowing what had happened. And when I made the 911 call I couldn’t even get out the words," she said.

"That was the worst day of my life and I know it always will be," Alandt read through tears.

Funke said she thinks every day why she got to live and her friends did not, and said she felt "sick with guilt" when she looked at her friends' families.

She said the crime has left her terrified. She said she slept in her parents' room for nearly a year and made them double lock each door. She said she has never slept through the night and constantly wakes up in panic, worried that someone is breaking in, trying to hurt her or someone she loves.

Video shows Bryan Kohberger’s family visiting him in custody on the eve of his sentencing.

Kohberger's parents attended his change of plea hearing on July 2, their first time in court with their son since his arrest in Pennsylvania more than two years ago. Attorneys for the Kohbergers said in a statement at the time, "The Kohbergers are asking members of the media for privacy, respect, and responsible judgment during this time. We will continue to allow the legal process to unfold with respect to all parties."

President Donald Trump weighed in on the case on social media Monday, saying he thinks Bryan Kohberger should be required to reveal a motive.

"I hope the Judge makes Kohberger, at a minimum, explain why he did these horrible murders," he wrote. "There are no explanations, there is no NOTHING. People were shocked that he was able to plea bargain, but the Judge should make him explain what happened."

The family of 21-year-old victim Kaylee Goncalves thanked Trump for "pushing for justice," saying in a statement to ABC News, "A confession without clarity does not bring peace."

"If the defendant is permitted to live, the bare minimum he owes us, and this country -- is an explanation," the family said.
