Presence of fecal material in diapers as a potential source of error in estimations of postmortem interval using arthropod development rates.

Second instar larvae of the fly Chrysomya megacephala (Diptera, Calliphoridae) were recovered from the diapers of a 16-month-old child abandoned by her mother on Oahu, Hawaii. The development of these larvae indicated a minimum period of 23.5 h of exposure prior to discovery of the child. Larvae of this species of fly are not normally associated with living tissues in Hawaii, but rather with feces and remains during the early stages of decomposition. Had the child in this case died and data not been provided detailing the site of infestation, the postmortem interval estimated would have been significantly longer than was actually the case, because of the development of the larvae inside the diapers of the living child. The need for caution in cases involving deaths of infants, the elderly, and individuals not capable of caring for themselves is stressed.     

Decision games applied to police decision making -an exploratory study of information usage-

An analysis of police decision making is presented using the decision board technique developed by Leslie Wilkins. This method assumes that decision making can be measured by observing a subject's response to stimuli presented in the form of pieces of information. A board was created and employed with fifty municipal police officers. Findings suggest that police demonstrate individualized preferences for varying amounts and kinds of information. The nature of the offense was considered most frequently. The attitude of the offender was also an important determinant of the decision outcome; and the offender's attitude then influenced the amount and type of information subsequently used.
