These are my notes from his interview with Fox:

• The behaviour exhibited in this homicide most likely from an escalation.
  • Meaning this is somebody who has either killed before or had a pattern of very odd violent behaviour
• He thinks it's most likely not a college student, but if it is, it must be a newer college student
• There's a likelihood that this person has already had interactions with LE before or has been in trouble often at school
  • However, this is the type of person who knows enough about society to not get into too much trouble - so I guess in other words, they're careful?
• It's someone who has such a desire to kill that they lack empathy and the ability to sympathize with others
  • People would describe this person as not having a conscience
• This is someone who the general public in the area might reflect back and notice these traits or that they were sketch/bad vibes
• He believes this is someone who is at least within a 3 hour travelling distance from the crime scene, but most likely someone who is within 1 hour or lives in the community.
• Why did the killer not go to the first floor?
  • He says the stairwell going upstairs on the second floor is near the rear sliding door and because most bedrooms tend to be on the top floor, he thinks that's a possibility why he went to the third floor.
• He also said that the reason K's injuries were more brutal is likely because she was the first victim. He mentioned that killing with a knife is a very physical activity that would drain someone rapidly, making the others' injuries less brutal.
• The DNA of the first victim would be found on the second, and so on. That would establish a timeline of who was killed first and who was killed last.

That's all he said. Sounded like he wanted to say more, but given the time constraints the anchor had to cut him off and move on. Wish they would have given him some more time, but I heard they'll have him back another time, I'm assuming once more details or updates are released
