Editing Serial killer (section)

====Communication====
The FBI handbook (2008) and Keppel (1989) both stress communication as paramount. The difference is that the FBI handbook concentrates primarily on communication within a task force, while Keppel makes getting information out to and allowing information to be passed back from patrol officers a priority.<ref name="FBI-2010"/><ref name="keppel1990"/> The FBI handbook suggests having daily e-mail or in-person briefings for all staff involved in the investigation and providing periodic summary briefings to patrol officers and managers. Looking back on a majority of serial murderer arrests, most are exercised by patrol officers in the course of their everyday duties and unrelated to the ongoing serial murder investigation.<ref name="egger1998"/><ref name="keppel1990"/>

Keppel provides examples of Larry Eyler, who was arrested during a traffic stop for a parking violation, and Ted Bundy, who was arrested during a traffic stop for operating a stolen vehicle.<ref name="keppel1990"/> In each case, it was uniformed officers, not directly involved in the investigation, who knew what to look for and took the direct action that stopped the killer. By providing up-to-date (as opposed to periodic) briefings and information to officers on the street the chances of catching a serial killer, or finding solid leads, are increased.
