Criminal profiling principles suggest that a low-risk victim is statistically more likely to be victimized by someone who is known to them or who knows them.

“but when you get to a low-risk person, it's much different because statistically a low-risk victim is going to be victimized by someone who's known to them or at least knows them.”

The investigation should prioritize pre-abduction behaviors like boundary probing and post-abduction behavior such as radical changes in a suspect's normal routine.

“So we think of it into two uh kind of general camps uh for investigation. One's the pre-abduction, then the post-abduction. We kind of have an idea what happened during the abduction.

“Plus, sweet Steven, they say that all you have to do is look at what was left behind to know that he is the victim of foul play, too. Because remember how his clarinet was found in the orchestra pit? Like, everyone’s like, he loved that thing. Like, that thing was his baby.”

Effective criminal profiling requires analyzing the killer, the victim, and the situational context.

“When you go into profile a killer, really the best way to do that is you have to profile everything. You have to profile the killer, you profile the victim, you profile the area and the situation.”

Criminal profiling involves understanding why and how a crime occurred, which can help reveal the perpetrator's identity.
