Bryan Kohberger’s Costco Video & The Psychology of Calm After Killing

They kill.

Then they smile for cameras, clock in for work, or go grocery shopping.

In this chilling Hidden Killers investigation, we explore “The Performance of Normal” — the haunting calm that follows murder. Starting with Bryan Kohberger, who prosecutors say was seen casually shopping hours after the brutal Idaho student murders, we dive deep into the psychology behind that eerie stillness.

Why do some killers seem completely composed after committing horrific crimes?

From John List, who ate lunch next to his wife’s body before vanishing for 18 years…

To Dennis Rader (BTK), who left a Boy Scout camp to murder and came back by morning to flip pancakes for the troop.

To Chris Watts, who went to work just hours after killing his pregnant wife and daughters.

To Stephen McDaniel, who gave a TV interview about his “missing” neighbor — the same woman he had just murdered.

To Colonel Russell Williams, a respected Canadian military commander smiling for charity photos days after taking a life.

To Tyler Hadley, the Florida teen who killed his parents, then threw a party with their bodies hidden in the next room.

To Susan Smith, the mother who tearfully begged for her children’s return after drowning them herself.

And Ian Huntley, the school caretaker who joined the search for two girls he had already murdered.

This episode examines the psychology of composure — how killers weaponize calmness, and why society so often mistakes it for innocence.

It’s not just what they do. It’s what they don’t.

Because sometimes, evil doesn’t look like rage.

It looks like control.

It looks like “normal.”
