A shocking eyewitness account from a surviving roommate in the University of Idaho murders "changes a lot" in the case, Fox Nation’s Nancy Grace said Friday.

The surviving roommate, identified only as D.M. in the unsealed probable cause affidavit, came face-to-face with the masked killer inside the house and heard him speak.

Moscow police reported D.M. "saw a figure clad in black clothing and a mask that covered the person's mouth and nose walking towards her… The male walked past D.M. as she stood in a ‘frozen shock phase.’" He then exited through the second floor doors. 

She was able to describe to officials the suspect’s height and "bushy eyebrows," Fox News' Lawrence Jones reported.

Grace said D.M.’s account will hold significant weight during the trial for suspect Bryan Kohberger.

"She says she hears one roommate crying, whimpering," Grace explained. "And freakily, you hear what we believe to be the defendant say, ‘Hey, it's OK, I'm going to help you.’"

"That will move any jury," Grace said on "America's Newsroom."

And while Grace conceded the affidavit had only enough information to get the arrest warrant, she believes the recorded eyewitness account and accompanying DNA evidence are grounds for a conviction.

Steve Goncalves, father of victim Kaylee Goncalves, called the new revelation from the affidavit "shocking" and "bizarre" when he spoke to "Fox & Friends" Friday morning.
