I watched as the young mother told her kids, still sitting in the car, to behave if they wanted candy, before she walked into the store. Then I approached the passenger side, which was occupied by a seven-year-old girl with short blonde hair.

"How would you like a surprise?" I asked.

The girl looked at me for a second, and said "okay."

"Close your eyes."

She closed her eyes.

I pulled a Glock from my shirt and shot her in the side of the head. I ran, as the screaming of her siblings pierced the mostly-empty parking lot.
