Profilers

In this compilation of expert articles internationally recognized homicide investigators, most of them pioneers in developing the science and the art of profiling, share their insights gained from years of experience tracking the perpetrators of some of the most notorious crimes. Among the subjects discussed are: dealing with hostage situations, child abduction and murder in the David Meirhofer case, interviewing Jeffrey Dahmer, autoerotic murder, the challenges of creating psychological profiles, the use of forensic linguistics to track the Unabomber, assaultative eye injury ("enucleation"), and geographic profiling. A must for readers of true crime, forensic investigations, and murder mysteries, this unique collection of revealing articles offers a chilling and unparalleled glimpse into the workings of the criminal mind.

In 1990, a young woman was strangled on a jogging path near the home of Pat Brown and her family. Brown suspected the young man who was renting a room in her house, and quickly uncovered strong evidence that pointed to him -- but the police dismissed her as merely a housewife with an overactive imagination. It would be six years before her former boarder would be brought in for questioning, but the night Brown took action to solve the murder was the beginning of her life's work. Pat Brown is now one of the nation's few female criminal profilers -- a sleuth who assists police departments and victims' families by analyzing both physical and behavioral evidence to make the most scientific determination possible about who committed a crime. Brown has analyzed many dozens of seemingly hopeless cases and brought new investigative avenues to light. In The Profiler, Brown opens her case files to take readers behind the scenes of bizarre sex crimes, domestic murders, and mysterious deaths, going face-to-face with killers, rapists, and brutalized victims. It's a rare, up-close, first-person look at the real world of police and profilers as they investigate crimes -- the good and bad, the cover-ups and the successes.

High-speed non-contact laser profilers have become the standard testing equipment for pavement management ride quality testing. The same technology used in the high-speed profilers is now being used in lightweight profilers for construction smoothness testing. The lightweight profilers have many advantages over the California 25-ft profilograph. Despite the many advantages of the lightweight profilers, there is resistance from the contracting industry toward eliminating the 25-ft profilograph for construction ride testing. One way to reduce or overcome the resistance is to evaluate and demonstrate the advantages/disadvantages of the lightweight profiler in actual field use in Iowa. The objective of the study was to purchase a lightweight profiler and to evaluate its suitability for construction smoothness quality verification and quality acceptance on Iowa projects. A lightweight profiler, an Ames Engineering, Inc. LISA single laser unit, was received in February 2003 for the study. Based on the work done during the 2003 construction season, the following conclusions can be made: (1) For hot mix asphalt surfaces, the LISA correlated well with the contractors' profilographs; (2) LISA results are significantly affected by longitudinal tining on portland cement concrete pavements, requiring a laser system upgrade to give accurate results; (3) A significant time saving was realized by using the LISA; (4) Increasing visibility and reducing time in the construction zone improved safety; (5) One person with limited lifting capabilities could set up and operate the LISA; and (6) With the current Iowa Department of Transportation specification, the LISA cannot totally replace the profilograph, since bridges and short segments with no adjoining pavement would still require a profilograph.
