'Just an FYI while we are waiting for something to break in this case'.
Myth: Serial killers are only motivated by sex.
All serial murders are not sexually-based. There are many other motivations for serial murders including anger, thrill, financial gain, and attention seeking.
• In the Washington, D.C. area serial sniper case, John Allen Muhammad, a former U.S. Army Staff Sergeant, and Lee Boyd Malvo killed primarily for anger and thrill motivations.

Myth: All serial murderers travel and operate interstate.
Most serial killers have very defined geographic areas of operation. They conduct their killings within comfort zones that are often defined by an anchor point (e.g. place of residence, employment, or residence of a relative). Serial murderers will, at times, spiral their activities outside of their comfort zone, when their confidence has grown through experience or to avoid detection.

Myth: Serial killers cannot stop killing.
It has been widely believed that once serial killers start killing, they cannot stop. There are, however, some serial killers who stop murdering altogether before being caught. In these instances, there are events or circumstances in offenders’ lives that inhibit them from pursuing more victims. These can include increased participation in family activities, sexual substitution, and other diversions.

Myth: Serial killers want to get caught.
Offenders committing a crime for the first time are inexperienced. They gain experience and confidence with each new offense, eventually succeeding with few mistakes or problems.
While most serial killers plan their offenses more thoroughly than other criminals, the learning curve is still very steep. They must select, target, approach, control, and dispose of their victims. The logistics involved in committing a murder and disposing of the body can become very complex, especially when there are multiple sites involved.
As serial killers continue to offend without being captured, they can become empowered, feeling they will never be identified. As the series continues, the killers may begin to take shortcuts when committing their crimes. This often causes the killers to take more chances, leading to identification by law enforcement. It is not that serial killers want to get caught; they feel that they can’t get caught.
