A serial killer is defined as someone who murders three or more victims over a relatively short interval. Though it has been said that serial killers often fail to keep jobs for long periods of time, such as Ted Bundy, who held a number of low-end jobs, some psychologists also claim that serial killers can appear to be completely normal and have high-functioning lives. John Wayne Gacy, for example, was a highly respected individual within his community, and Dennis Rader was the elected president of his church.
Though many assume that most serial killers are rooted in violent families and abusive upbringings, there are many examples of serial killers who grew up in normal families with surprisingly average childhoods. Thus, it's hard to pinpoint conclusive personality characteristics of serial killers since the motives for killing can vary anywhere from wanting to be a hero by saving victims they previously poisoned, to sick and sadistic pleasure.
Here's a list of serial killers who had surprisingly normal jobs, although some are a bit creepy. Ice cream truck driver, anyone?

Between 1978 and 1991, Jeffrey Dahmer killed 17 men before he was sentenced to 15 consecutive life terms in 1992. Dahmer had an alcohol abuse problem that led to his Army discharge. After he was kicked out of the Army, Dahmer moved in with his grandmother in the hopes that he could clean up his act, though she later asked him to move out after discovering disturbing things in her home. Dahmer was arrested in 1991 and eventually admitted to all 17 murders. Dahmer pled "guilty but insane" to 16 counts of murder and was given 16 sentences of life imprisonment. In 1994, he was murdered in prison.
