I'll be back. To be interpreted as - bang, bang, bang, bang - ugh. Yours in murder, Mr. Monster." (Crime library) This letter was found at the scene of one of his crimes. He eventually confessed to the murders of 28 women. However, many believe the number of deaths to be much higher (Crime Library).
Serial murderers can be either organized," carrying out planned, premeditated attacks on strangers, or disorganized, committing unplanned killings and behaving haphazardly. Other clues-or lack of them-identify organized killers. They often hide their identities by wearing gloves and a mask, and may carry a "toolbox"" containing, for example, duct tape and rope for restraint (Platt, Richard). In their younger years, it's been found that the killer's father had a steady job, but there was a lack of discipline. The organized killer would be disruptive in school and would externalize his/her hurt, anger and pain. He/she would be very intelligent, but would be a bully and probably just squeaked by in school. They have good verbal skills and may be good con artists. Many have been in the military or have had jobs that allow them to see themselves in positions of power. They would have some personal contact with their victim beforehand, and are aware of the importance of evidence that may be left behind. Rape and torture may occur before the murder for personal gratification, and they hide the bodies of their victims. Their outward appearance is pleasing. A disorganized serial killer, on the other hand, kills quickly and without planning, they don't bring "toolbox"", and there is no personal contact until the moment of the murder. They don't think about the evidence, and usually there will be no rape or torture, and usually does not hide the body well. As for his/her younger life, the disorganized killer would have a father that couldn't hold a job. The discipline would be very harsh and he would internalize his pain.
