Developing Outcome Measures for Criminal Justice Information Sharing: A Study of a Multi-Jurisdictional Officer Notification System for Policing Sex Offenders in Southern California

Information-sharing efforts are broadly assumed by criminal justice and security practitioners to be effective, yet their impact on policing performance has not been thoroughly studied. This paper develops measures for an information-sharing system in a population of sex offenders in Southern California. We compared interagency involvement and policing outcomes for registered sex offenders with (n = 3,919) and without (n = 581) records pertaining to their sex offender status in the Officer Notification System (ONS) of ARJIS. To account for differences in criminal activity, offenders were matched on each of four focal incidents (citations, field interviews, crime cases, and arrests) and compared on outcomes that followed the focal incident. Compared to controls, sex offenders with ONS records were 75 % more likely to be involved with multiple agencies, 92 % more likely to have a citation following a crime case, 34 % more likely to have multiple crime cases (i.e., a crime case following an initial crime case), 44 % more likely to have a field interview following a citation, over 2 times more likely to have a field interview following a crime case, and 20-30 % more likely to have an arrest after a crime case, citation, or field interview. Novel measures of information sharing revealed links between the sharing of information about sex offender registrant status and the frequency and timing of police incidents and inter-agency involvement.

Fast gas chromatography of explosive compounds using a pulsed-discharge electron capture detector

The detection of a mixture of nine explosive compounds, including nitrate esters, nitroaromatics, and a nitramine in less than 140 sec is described. The new method employs a commercially available pulsed-discharge electron capture detector (PDECD) coupled with a microbore capillary gas chromatography (GC) column in a standard GC oven to achieve on-column detection limits between 5 and 72 fg for the nine explosives studied. The PDECD has the benefit that it uses a pulsed plasma to generate the standing electron current instead of a radioactive source. The fast separation time limits on-column degradation of the thermally labile compounds and decreases the peak widths, which results in larger peak intensities and a concomitant improvement in detection limits. The combination of short analysis time and low detection limits make this method a potential candidate for screening large numbers of samples that have been prepared using techniques such as liquid-liquid extraction or solid-phase microextraction.     

The determination of nicotine and sulfate in supermarket ground beef adulterated with Black Leaf 40

In December 2002, approximately 250 lbs. of ground beef was adulterated with nicotine sulfate by a supermarket employee and subsequently sold to the public. Soon afterward, reports of illness associated with ground beef purchased at a single store were identified. Authorities suspected the ground beef was tainted with Black Leaf 40, a banned pesticide containing approximately 40% nicotine as nicotine sulfate. Ground beef submitted to our laboratory was analyzed in concert by high performance liquid chromatography-ultraviolet detection (HPLC-UV), gas chromatography-mass spectrometry (GC-MS), and high performance anion exchange chromatography with suppressed conductivity detection. GC-MS was used to identify the samples that contained nicotine. The nicotine was confirmed and quantitated by HPLC-UV. The sulfate was identified and quantitated by high performance anion exchange chromatography with suppressed conductivity detection. Our analysis revealed that the raw tainted beef contained about 350 mg/kg nicotine free base, a potentially lethal dose of nicotine per serving for an adult. Additionally, we found elevated sulfate levels in the samples that tested positive for nicotine, providing evidence that nicotine sulfate was the probable adulterant.     

LAP-banding obesity: a case of stomach perforation, peritonitis, and death

We present a case of peritonitis and death due to the misplacement of a laparoscopic adjustable band inserted through, instead of around, the stomach. This represents the first case in the published literature where a LAP-BAND perforated the stomach, followed by peritonitis and death. The morbidly obese female patient with a history of hypertension and arthritis was 47 years old, 5 feet 6 inches tall, weighed 361 pounds, and had a body mass index of 58.3. She underwent a 2-hour, elective, LAP-band insertion operation to achieve weight loss; 27 hours after band insertion, following the conduction of all FDA-mandated Lap-Band postoperative protocol (including a radiologic Gastrogrografin swallow), the patient was discharged with "no evidence of esophageal stasis or obstruction." She remained out of hospital care and in her residence until she called for and was taken by an ambulance to an alternate, local hospital (57 hours after band insertion), when gastric perforation was confirmed via x-ray and CT scans. No open surgery was attempted to repair the damage, and cardiac arrest ensued 7 hours after admission to the second hospital. The patient was pronounced dead 64 hours after LAP-band insertion. This unique case is significant, given that there were no deaths of this kind reported in The LAP-BAND(R) Adjustable Gastric Banding System Summary of Safety and Effectiveness Data by the United States Center for Devices and Radiologic Health, of the Food and Drug Administration, or in searches of the published literature.
