All serial killers want to win. They choose victims they can kill successfully.

The one noticeable similarity with almost all serial killer victims is their short height and low weight.

Most well-known serial killers have victims numbering in the dozens, have sent taunting letters to the police or have done bizarre things to the bodies.

Nowadays, with much more racial and ethnic mixing, we are seeing serial killers murdering a variety of victims; whoever comes along will most likely do.

We assume people we know can't be serial killers.

Often, a serial killer has no felony record.
