Lewis, who was charged with obstructing justice in the case, is testifying against Baum as part of an agreement with prosecutors and will be released from jail after Baum’s case is finished, court records show, theDeseret Newsreports.

On Wednesday she explained how Baum allegedly flew into a rage when he found her smoking marijuana with Powell and Otteson at their home in Mammoth on Dec. 29, according to a probable cause statement filed at the time of his arrest, theDeseret Newsreports.

She said Baum then allegedly bound the teens’ hands and feet and duct-taped their mouths and put them in Powell’s Jeep, theDeseret Newsreports.

After ordering Lewis into the Jeep, Baum allegedly drove them all to an abandoned mine shaft in the Utah desert near Eureka, according to the probable cause statement.

Carrying a knife in his hand, Baum, who Lewis described as eerily calm, allegedly ordered her and Otteson to get down on their knees in an “execution-style” pose, she testified.

When Otteson started to cry, Powell asked Baum if he could kiss her.

That’s when Baum did the unthinkable, she testified, allegedly hitting Powell and then repeatedly stabbing him with the knife before slitting his throat.

With tears running down her face, Otteson begged Baum to spare her life, telling him she wouldn’t tell a soul what she had just witnessed, Lewis testified.

Taking Otteson in his arms, Baum held her and said softly, “It’s OK, darling,” and then slit her throat, Lewis alleged.

Baum then allegedly threw the teens’ bodies into the cavernous 1800-foot hole, which landed on a ledge about 100 feet down, as Lewis cried, she said.

After Baum allegedly killed the teens, Lewis testified, “He looked manic. He looked overjoyed. He’s got this huge grin on his face like he’s enjoying himself. He did later laugh about it and said that it was like lambs to the slaughter.”

The teens werereported missingJan. 2, 2018. Their bodieswere recoveredon March 28, based upon information from Lewis, the sheriff’s office said ina previous news release.

Baum’s attorney did not immediately return PEOPLE’s call for comment.
