Findings indicate a plethora of psychiatric disturbances and odd/reclusive and acting-out personality traits. Predisposing factors include a fascination with weapons and war among many of the adolescents and the development of a "warrior mentality" in most of the adults. Precipitating factors indicate a major rejection or loss in the hours or days preceding the mass murder. Results are interpreted through the lens of threat assessment for targeted violence (Borum, Fein, Vossekuil, & Bergland 1999), recognizing that a fact-based, dynamic behavioral approach is most useful for mitigating risk of such an extremely low-base-rate violent crime.

Archival files of 25 forensic subjects whose alleged criminal offenses met a legal definition of stalking behavior were studied for demographic characteristics, stalking dynamics, psychosocial history, ...

The authors briefly critique the clinical concept of battered woman syndrome and review current federal and state case law relevant to its use as a criminal defense. Despite the fact that the U.S. Supreme Court has yet to hear a case involving testimony concerning battered woman syndrome, its scope as a criminal defense is expanding.

A static group archival design utilized a non-random group of convenience and a randomly selected comparison group. Sixty-five obsessional followers and 65 offenders with mental disorders were evaluated by psychiatrists and psychologists for court ordered reasons during their criminal proceedings. Both groups were evaluated during the same period, in the same court diagnostic clinic, and generally for sentencing determinations. The obsessional followers were measured on demographic, diagnostic, pursuit, victim, threat, violence, emotional, motivational, and defense variables. Inferential comparisons that used parametric and nonparametric statistics were done within and between groups on select variables. The obsessional followers had significan...

Sadism was measured using the Millon Clinical Multiaxial Inventory-II (MCMI-II) Scale 6B, the Personality Disorder Examination (PDE) items for sadistic personality disorder, and the sexual sadism criteria of DSM-IV. Psychopaths were found to be significantly more sadistic than nonpsychopaths (MCMI-II and PDE). Overall power was relatively high. Sadism did not differentiate the violent and sexually violent groups. A diagnosis of sexual sadism was too infrequent (n = 3) for meaningful statistical analysis. The trait measures of sadism and psychopathy measures (PCL-R, Factor 1 and Factor 2) significantly and positively correlated. Results provide further empirical validity for the theoretically proposed and clinically observed relationship between sadistic traits and psychopathi...

Following a month of pursuit of a female stranger with whom he had briefly conversed in a local bar, he assaulted an automotive plant where she worked, delusionally believing that she was at imminent risk and needed to be rescued. One plant manager was killed and two police officers were wounded. The case illustrates the phenomenon of triangulation, where rage toward the rejecting object is displaced onto a third party, which is then perceived as impeding access to the victim and may be at risk for violent assault.

Intoxicated with alcohol at the time, the man positioned the corpse of his spouse to facilitate vaginal intercourse with her in the lithotomy position while he viewed soft core pornography on television. Clinical interview, a review of history, and psychological testing revealed diagnoses of antisocial personality disorder and major depression (DSM-IV, American Psychiatric Association 1994). There was no evidence of psychosis, but some indices of mild neuropsychological impairment. The motivations for this rare case of pseudonecrophilia are discussed in relation to extant research, and a cautionary note is offered in assuming sexual causality in the investigation of homicides when there is evidence of sexual arousal or activity by the perpetrator.

The relationship between variability of primary process intensity and the Thought Disorder Index produced a negative correlation at the 0.05 level of significance. Variability of primary process intensity was not found to be significantly related to the length or frequency of the dreams. This inverse relationship between formal thought disorder and variability over time of primary process in the dreams of biological relatives of schizophrenics suggested that dream constriction could be a regressive marker in the heritability of schizophrenia.
