Graphical Portrait of a Mass Killer

Nothing in the profile of Christopher Jordan Dorner the most recent mass shooter in the news surprises me.  It might have a few months ago, but after going through the details of 53 mass killings and looking at some of the details about the killers and their lives, the story seems sadly familiar.

Alleged cop-killer details threats to LAPD and why he was driven to violence

 1) Mr. Dorner is ex military and law enforcement.

  • 27 percent of the 53 killers I looked up were ex Military (2% were law enforcement), this is almost three times as high as in the general population (9 - 10%). 

 2) Mr. Dorner complains of racism, bias and corruption in his former workplace

  • 34 % of the 53 Killers made complaints of bias, racism, bullying or other forms of discriminatory actions against themselves or others.  Some of these claims were substantiated, some were not and in some cases it will never be know if there was any truth in the allegations.
3) He was recently terminated from the LAPD, and had recently undergone disciplinary action

  • When it comes to workplace violence, this is the most common thread among the killers. 30% of the 53 killers I looked at had undergone recent disciplinary action, including termination.  Also 57% of the killers were described as unemployed, many of them having recently lost their jobs (compared to ~7% in the general population).


  •  Recent major life stressors including being terminated is also another common feature among many of the killers (60% had either just been terminated, disciplined, divorced, been unable to find a job, been in court for custody hearings or lost a loved one etc.)



4)  There were complaints about his temper from colleagues and his ex wife

  • 49% of the 53 killers had a documented history of anger
 Here are some other statistics about the 53 Mass killers that I looked up:

Location of Killings (note many of the University killings can also be placed under the 'workplace' heading, making the workplace the most frequently targeted area).  Most of the residential killings were a result of domestic violence shootings.

Here I looked to see if the perpetrators had a criminal history, in light of the recent push to restrict gun ownership to 'law abiding' citizens, it is worthwhile to note that 60% of the killers had no criminal records.

47% had documented histories of mental health disorders/illness (the rate of mental health issues in the general population is around 50% while that of mental illness is around 20% and that of serious mental illness around 6%) , others showed signs of possible mental illness, however one thing of note is that several were either on, or had recently stopped a powerful antidepressant (it would be interesting to see if there was any correlation between the medications and the crimes).

This last one addresses the 'loner' stereotype.  This one is a hard one to measure, as some had at one time been outgoing and then became less outgoing after a life stressor, others were depressed and as such became withdrawn and some were true introverts.  However the idea that all of them were people with no social interactions (or very few) is not correct, many were married, some had children, others had been in relationships but were no longer in them.

Immigrants: ~20% of the killers were immigrants, it interesting to note that all of the killers of Asian descent were recent immigrants.

About Me

I am always fascinated by the disconnect between what the world is telling us and what we choose to believe. I hope this blog causes you to think about what you are being told by those around you, by the media and politicians. I don't expect you to agree with me and I graph things that are of interest to me, the point is not to bring you to my point of view, but to show you that sometimes the world is not the way we think it is.
