Inside the Idaho case

This about 4 idaho students who are Madison, Kaylee, Xana and Ethan. They got murdered by Bryan Kohberger. There were 2 other students in the house at the time that apparently didn't hear anything but saw Bryan walk out. There were ring cameras that were uploaded 2 hours before the murder, that heard screams apparently by Xana. Bryan originally was going after Kaylee and Madison, but Xana caught him in the act so he had to go after her first then Ethan. He is now in jail, but he said something about "did you catch anyone else" so that makes us think that there are more people that were in on it.
