Organization
There is the disorganized killer and the organized killer. Most serial killers(about 3/4) are organized and their victim counts seem to be higher, that is also because they are usually above average intelligence. The disorganized offender is lonely and his murders usually display his anger, most are of a low IQ and suffer from some mental disorder, the killing is not planned and is a usually spur of the moment thing. It should also be noted that some serial killers display both the characteristics of a disorganized and organized killer, these killers are typed as being 'mixed'. The characteristics do not apply all of the time but they are usually 3/4 applicable to the organization of the killer. These are the basic typologies -
Method
Organized Killer(eg. Gacy, Bundy) -
Will use a car in good condition for transport to the crime scene(this may be used later for transport of the victim, dead or alive).
Plans out the murder(may become accustomed to using it quickly).
Will bring a 'rape kit'(rope, handcuffs, chloroform etc) if desired.
Personalizes himself with the victim(talks, leads, captures etc. the victim into/for planned murder situation).
Rape, torture etc. may take place before murder, for the killers own gratification.
The murder may be a long and delayed process to fufill the killers planned fantasy.
Is aware of evidence left at crime scene(which may cleaned, destroyed etc).
Might move the body to hide, bury it etc. in an attempt to evade/delay discovery.
Killer will not be involved further with the victim's body, but may take articles, jewellery etc. for trophy or gain.
May be further interested in the crime(eg.taking part in a victim hotline), or may communicate with police, media, or relatives of the victim.
Disorganized Killer(eg. Berkowitz, Chase ) -
Usually walks to and from the crime scene, may use a car but the car will be in bad condition.
Murder usually happens spur of the moment(with no planning but the one simple objective to kill).
Does not bring any tools('rape kit') to the kill except maybe murder device.
No contact with the victim prior to spur of the moment murder.
No rape, torture etc. will take place before murder.
The murder will be a blitz style attack, fast and furious. The victim may sustain many wounds as a high degree of violence takes place.
Does not care for evidence usually left at the crime scene.
Will not move body in an attempt to hide, bury it etc., unconcerned of its discovery.
Killer might be involved further with the dead victim(mutilation, necrophilia, cannibalism, etc) and may also take souvenir(death/ fetishism).
Will take no or very little interest in the crime after it has been committed.

Lifestyles
These are the keypoints in a serial killers life after their youth and when they are killing or may soon do so. These keypoints also apply to homosexual serial killers as I did refer to the keypoints as heterosexuals but homosexual serial killers are also applicable.
