An Idaho woman frantically pleaded for her husband to calm down before he allegedly shot and killed her and her unborn child last week, according to new documents filed this week in the murder case of Jeremy Albert Best.

Best, 48, was arrested Saturday, two days into a manhunt that led police to the side of an Idaho road where Best was found naked in a sleeping bag along with his 10-month-old son Zeke, who was also found dead nearby.

Best has so far been charged with two counts of first-degree murder in connection with the deaths of his wife Kali Randall Best and their unborn child, while police say they are still investigating the death of the couple’s infant son Zeke.

According to court documents, Best was initially charged with two counts of second-degree murder, both of which were amended to first-degree murder on Monday.

In a new affidavit filed this week and reviewed by PEOPLE, details of a 911 call made from someone inside the family’s Teton County, Idaho, home last Thursday night show what happened moments before Kali, 38, was shot and killed.

The caller hung up before a dispatcher answered, but audio captured a snippet of the scene inside the family's home moments before shots were fired.

“Jeremy! Jeremy, no!” a woman’s voice could be heard yelling on the other end of the call, the probable cause affidavit shows.

The affidavit says a “male voice” is then heard in the background repeating “yes” in response before yelling out, “Get the f--- back, you’re gonna get shot!”

The male voice is then heard repeating, “I love you, I love you, I love you," before the call ends.

The affidavit says a Teton County Sheriff’s Office deputy was then dispatched to the family’s home to check in on the caller.

When the deputy arrived, they found a concerned neighbor outside who heard Best and Randall loudly arguing moments beforehand.

The neighbor told the deputy he heard Kali yell, “Jeremy stop it, you have a baby!” before five gunshots then rang out. The neighbor said he then saw a black vehicle flee from the scene.

The deputy then found Kali dead inside the home with three gunshot wounds in her back and right side. Her husband and their 10-month-old child were missing.

Authorities searched for Best and baby Zeke for two days before a group of hunters allegedly happened upon him laying naked inside a sleeping bag alongside an Idaho roadway roughly 60 miles away from the family’s home.

Best was allegedly “making odd statements” when the group of hunters found him, the Bonneville County Sheriff's Office said in a statement over the weekend. After he was medically cleared, Best was taken into custody and arraigned in court Monday.

Brian Randall, Kali’s brother, told PEOPLE last week that the family was unaware of any existing issues between the Idaho couple.

Kali’s brother previously told PEOPLE his sister “was absolutely a genuine beautiful soul” and that he never suspected Best of being anything but “a normal guy.”

"Sometimes maybe you don't know people,” Brian said, tearfully.

Randall's family released a statement to the media, including PEOPLE, thanking the public for their support in recent days.

“Our Zeke is now at rest with his loving mama and unborn sibling,” the family said. “The pain we feel is unimaginable and we thank everyone for their support. You will never know how you have lifted our family up during this time."
