Jack the Ripper Dear Boss I keep on hearing the police have caught me but they wont fix me just yet. I have laughed when they look so clever and talk about being on the right track. That joke about Leather Apron gave me real fits. I am down on whores and I shant quit ripping them till I do get buckled. Grand work the last job was. I gave the lady no time to squeal. How can they catch me now. I love my work and want to start again. You will soon hear of me with my funny little games. I saved some of the proper red stuff in a ginger beer bottle over the last job to write with but it went thick like glue and I cant use it. Red ink is fit enough I hope ha. ha. The next job I do I shall clip the ladys ears off and send to the police officers just for jolly wouldn’t you. Keep this letter back till I do a bit more work, then give it out straight. My knife’s so nice and sharp I want to get to work right away if I get a chance. Good luck. Yours truly Jack the Ripper
Serial Murder Symposium • Created by Behavioral Analysis Unit-2 (BAU-2) of National Center for the Analysis of Violent Crime (NCAVC) • Focus on serial, mass, and other murders; sexual assaults; kidnappings; and other criminal acts targeting adult victims • Expertise in serial murder, provide operational assistance, conduct research, and provide training on issues related to serial murder
Hollywood and the “Talking Heads Phenomenon” • Hollywood story lines create heightened interest rather than focusing on facts • Self-proclaimed serial killer experts are given credibility by the media • These fallacies and misinformation leads to inaccurate, fictional portrayals of serial killers creating a series of myths and misconceptions
Myth: Serial killers are all dysfunctional loners • Most hide within plain sight • Have families, homes, gainfully employed, blend in well and can be overlooked by police • Robert Yates • 17 prostitutes in Spokane, WA • Decorated US Army National Guard helicopter pilot • Green River Killer – Gary Ridgeway • 48 women in Seattle, WA • Religious, Married three times • BTK killer – Dennis Rader • 10 victims, Wichita, KS • US Air Force, married with kids, Boy Scout leader, president of church
Myth: Serial killers are all white males • Racial diversity of serial killers mirrors that of the overall U.S. population
Myth: Serial killers are only motivated by sex • Sex is not the only motivator • Others include: anger, thrill, financial gain, and attention seeking
Myth: All serial murderers travel and operate interstate • Most serial killers have defined geographical areas • Killings are conducted within comfort zones with a definitive anchor point (home, employment, relative's residence) • Moving outside the comfort zone is usually to avoid detection or when they become confident in their experience • Homeless transients • Itinerant individuals • Employment (i.e. truck drivers, military)
Myth: Serial killers cannot stop killing • Some things that cause serial killers to stop killing are: • increased participation in family activities, sexual substitution, and other diversions
Myth: All Serial killers are insane or are evil geniuses • Often suffer from a variety of personality disorders: • Psychopathy • Anti-social personality • Most, however, are not adjudicated as insane under the law • Media/“talking heads” have made serial killers out to be geniuses that stump the police at every turn (but they range in intelligence)
Myth: Serial killers want to get caught Practice makes perfect! • Serial killers gain experience and confidence with each new kill – make fewer mistakes with time • Must select, target, approach, control, and dispose of their victims with incredible planning • Begin to feel invincible and get sloppy when they begin to believe they CAN'T get caught!
Serial Murder • Serial Killing vs. Killing Spree vs. Mass Murder • Factors to consider: • Number of victims • Motive • Timing of events/cooling off period • Definition: The unlawful killing of two or more victims by the same offender(s), in separate events
Causality of Serial Killer • Biological, social, psychological and environmental factors in causality • Failure to develop adequate coping mechanisms results in violent behavior • Neglect and abuse early in childhood leading to future violence • Substance abuse • Severe head injuries
Psychopathy and Serial Killers • Personality disorder manifested in people who use a mixture of charm, manipulation, intimidation, and occasionally violence to control others, in order to satisfy their own selfish needs • Sensation seeking, a lack of remorse or guilt, impulsivity, the need for control, and predatory behavior • interpersonal traits include glibness, superficial charm, a grandiose sense of self-worth, pathological lying, and the manipulation of others • Not all violent offenders are psychopaths and not all psychopaths are violent offenders
Psychopath Interview: Talking the Talk • Not sensitive to altruistic interview themes (i.e. sympathy for victims, remorse/guilt) • Must exploit personality traits (i.e. inherent narcissism, selfishness, and vanity) • Past successful interviews of psychopathic serial killers focused on praising their intelligence, cleverness, and skill in evading capture
What is my motivation? • Normally in a murder investigation, suspects are those who have had relationships with the victims • In serial murders, this is mostly NOT the case. Serial murderers generally are not acquainted with their victims nor are they involved in consensual relationships with them • Motive is difficult to discern; may evolve • May be multiple motives • Motive may not be helpful in identifying killer • Generally they kill because they want to unless they are victims of severe mental illness
Investigative Issues and Best Practices • Identification of a Serial Murder Series • Leadership – establish lead investigator • Task Force Organization – one lead agency (many jurisdict.) • Resource Augmentation – less is more • Communication – daily investigator briefings, operational face-to-faces, ViCAP reports included in database • Data Management – put reports in database ASAP; keep “murder book”, all rough notes, & share reports with agencies/prosecutors • Analytical Tools – timelines, case similarities, filter info, interview and prosecution strategies, profiling, behavior analysis • Mes/Coroners – thorough/joint autopsies, missing person's database, submit remains to FBI
Investigative Issues and Best Practices • Administrative Issues – 50-yr minimum for files, keep unsolved till closed, electronic records, long-term evidence storage, submit reports to ViCAP • Resources and Finances – contingency plans for resources (FDP) • Training – dependent upon experience and ability; newbies need training and exposure! • Officer Assistance Programs – Debriefings, counseling, mental health evaluations, time off
Forensic Issues in Serial Murder Cases • Advances in technology, innovations in processing and collecting of evidence has allowed for greater success in recovery and analysis of evidence • DNA analysis is becoming more sensitive and discriminating • Can compare against a database of known offenders and other unsolved crimes, families of missing persons, etc. • CODIS – National automated DNA information processing and telecommunications system developed to link DNA evidence in criminal cases between jurisdictions • National, State and Local Levels (may not automatically search State and Local against the National database!)
Other Databases • AFIS – Fingerprint database • NIBIN – projectile/firing information database (bullets and cartridges)
Suggestions for Resolving Issues: • Utilize same crime scene personnel to promote consistency • Prevent cross-contamination (separate personnel collects crime scene vs. suspect/known samples) • Standardize documentation • Take aerial photographs as well as ancillary scenes • Ideally, evidence should be analyzed by a single certified crime lab by professionals; otherwise communication is paramount • Prioritize so there is quick turnaround on tests • Prioritize testing based on potential investigative value • Forensic testimony should be limited to what is needed for prosecution, utilizing charts, photos and audiovisual aids
Prosecution • Prosecution primarily plays an ADVISORY role • Can assist in critical decisions early on which can impact court admissibility of evidence and testimony • Must maintain legal integrity in investigation • Prosecutor involvement is especially important when dealing with multiple jurisdictions • Expert witnesses can also provide invaluable testimony to support the case
Media Concerns • Law enforcement-media relationship not always ideal • Design and implement an effective media plan • Communication with the media is counterproductive – serial murderer is the only one who benefits; may aid in avoiding detection • Respectful, cooperative relationship will benefit both • Suggestions: • Identify a spokesperson with limited access to sensitive case facts • Rehearse all verbal statements so they coincide with written • Press releases should have specific objectives, but remain positive • Squelch the talking heads! • Demand corrections or retractions of erroneous information
Recap of Serial Killers • Have more than 2 victims • Have a “cooling off” period in between • Typically: • Serial Killers work alone • Kill strangers • Kill for the sake of killing
