Why do serial killers target women?

There are several reasons why serial killers pick women. Almost all serial murder is about sex in some way. Even if the victim is not raped there will be other signs that the killer leaves that gives clues into his mindset. Jack The Ripper never raped any of his victims yet his were sexually motivated. The Zodiac of No. California never raped any of his victims, yet again there were certain sexual elements to his crimes.

Women as victims are simple for many killers. If the killer has sexual problems it seems logical he won't take out his anger on men. (unless he's homosexual) Women by their very being make for easier victims. They are smaller, weaker, and conditioned 'not to make a scene' from their earliest childhood. Also, many murder victims of serial killers have been known to work as prostitutes. That alone puts them in a higher risk factor. Prostitutes pick up strange men as a matter of business. The are frequently working in areas that are dangerous and have high crime rates. They also move around alot. If a 'working' girl has not been seen for a while, well that's just part of the job. And last by not least, working girls avoid the law. When you put all these triats together you get the perfect victim.
