Inside the mind of the serial murder

This article approaches a position of delving into the thoughts of those who commit murder serially. The information comes from a variety of sources which include research literature, theory examination and most importantly, serial murderers themselves. More than 400 cases of serial fatal violence as well as interviews with incarcerated serial killers were utilized. Important issues such as locus of motives, expected gains, victim selection processes, planning of the event, the murder event itself, and organization and disorganization of the kill are also discussed. While admitting that serial killers have never been rehabilitated, a call is directed toward a better understanding of the mind of the serial murderer.

Hypervariable regions of DNA for parentage testing and individual identification

Four kinds of DNA probes that recognize hypervariable regions (HVR) were studied for parentage testing and individual identification. Allele frequencies and their confidence intervals among unrelated Japanese individuals were obtained. Codominant segregation of the polymorphism was confirmed in family studies. Two a priori probabilities were calculated for each HVR locus: the exclusion probabilities for an alleged father/mother/child trio and for an alleged parent/child duo, and the probabilities of matching of genotypes of two unrelated individuals or two siblings. The ease of availability of the probes and their highly discriminating polymorphic patterns mean they could be very useful for forensic purposes.     

The shielding capacity of the standard military flak jacket against ballistic injury to the kidney

An animal model was designed to evaluate the ability of the standard military flak jacket to protect the kidneys from direct ballistic trauma. Yorkshire swine were anesthetized and their flanks were protected by flak jackets. Ballistic insults ranging from a low-velocity handgun to a high-velocity rifle were evaluated. The results demonstrate that a flak jacket provides adequate protection against low- and mid-velocity projectiles since none of the animals from this group had evidence of internal trauma and because only minor superficial surgical attention would have been required. Survivability in each case was considered to be excellent. The flak jacket failed to provide any protection against several types of high-velocity bullets. These weapons caused severe internal injury to the genitourinary system as well as to other major organ systems. Survival would have been unlikely.     

A photographic technique for the restoration of damaged radiographs

Occasionally during identification efforts, the forensic science team will encounter radiographs needed for comparisons that are damaged and seemingly useless. The simplified darkroom technique presented will facilitate the recovery of useful information from such compromised radiographs on film.
