At 4.07 a.m., the car drove in one last time, approaching the house at 11.22 King Road. So now it's time to go in and do this. It was just before 4.07 a.m. and pitch dark. The white car caught in these images obtained exclusively by Dateline, a car that had been captured on video for some 38 minutes on the streets around 1122 King Road in Moscow, had gone off camera and apparently parked nearby.

Inside the car, police believe, the driver and a knife with a seven-inch blade. The Marine Corps fighting K-Bar. What was going through the mind of the person carrying that knife? Dr. Brucato can only speculate based on his years of study.

To illustrate what might have happened inside the house on King Road in the minutes that followed, we had this animation built. It's based on the recollections of former residents and court records, police affidavits, real estate, and social media images of the house. And we've also spoken to sources close to the investigation who gave us their theories of what happened.

Sometime after 4.07 a.m., the killer entered the house on the second floor through an unlocked sliding kitchen door and went quickly and directly upstairs to Maddie Mogan's bedroom. Sources close to the investigation have told us that is one of the reasons they believe Maddie was the killer's target. But almost certainly to the killer's surprise, he discovered that Maddie was not alone.

Kaylee was sleeping in the same bed.

Kaylee was sleeping in the same bed.

The killer attacked anyway. There was a struggle. It was noisy. Multiple sources close to the investigation speculate that Zanna, downstairs in the second floor kitchen on TikTok, heard thumping and went to investigate. The killer must have heard this, our sources said, and turned his attention away from Maddie and Kaylee and began chasing Zanna. And in that kind of chaos, this thing gets dropped.

The thing being the sheath for the Ka-Bar knife, the one found on Maddie's bed. Those same sources have told us that with the killer in pursuit, Zanna desperately tried to reach her bedroom where Ethan was sleeping or was possibly passed out. But as she reached the bedroom, the killer was on her. What one source described as a hell of a fight ensued.

At 4.17 a.m., ten minutes after the suspect car turned in toward 1122 King Road, the security camera on that neighboring house picked up sounds, including what police described in charging papers as distorted audio of what sounded like voices or a whimper, followed by a loud thud. Here are those sounds. A dog began to bark. as if something was wrong.

Then multiple sources close to the investigation told us, with Zanna either dead or dying, the killer saw Ethan in bed, possibly passed out after a night of drinking. And with one swift blow of the knife, blood spatter shows, the killer struck an artery.

And then, according to our sources, the killer did something strange. He carved Ethan's lower legs. Carved is the specific word that was used.
