He played a significant role in the psychological profiling of violent offenders in the 1970s and is often credited with coining the term "serial killer", though the term is a direct translation of the German term "Serienmörder" coined in 1930 by Berlin investigator Ernst Gennat. After retiring from the FBI, he authored a number of books on serial murders, and often gave lectures on criminology. Early life Robert Ressler grew up on North Marmora Avenue in Chicago, Illinois and graduated from Schurz High School, Class of 1955.

Sheridan Reserve Center
The Philip H. Sheridan Reserve Center is the former Fort Sheridan now in Lake Forest, Highwood, and Highland Park in Lake County, Illinois, United States. It was originally established as a United States Army Post named after Civil War Cavalry General Philip Sheridan, to honor his services to Chicago. When the main fort was officially closed by the Army on May 3, 1993, the majority of the property was sold by the Department of Defense to commercial land developers. Most of the original housing structures were then refurbished and resold as a residential community. Other buildings were given to cultural organizations like Midwest Young Artists, the largest youth music program in the Midwest. Approximately of the southern end of the original post were retained by the Army; there the Army now operates the Sheridan Reserve Center complex. In celebration of the 2018 Illinois Bicentennial, Fort Sheridan was selected as one of the Illinois 200 Great Places by the American Institute ...

Colin Ireland
Colin Ireland (16 March 1954 – 21 February 2012) was a British serial killer known as the Gay Slayer because his victims were gay. Criminologist David Wilson believes that Ireland was a psychopath. Ireland suffered a severely dysfunctional upbringing. He committed various crimes from the age of 16 and had served time in borstals and prisons. While living in Southend, he started frequenting the Coleherne, a gay pub in Earl's Court, London. Ireland sought men who liked the passive role and sado-masochism, so he could readily restrain them as they initially believed it was a sexual game. Ireland said he was heterosexual: he had been twice married to women and that he pretended to be gay only to befriend potential victims. Ireland claimed that his murders were not sexually motivated. He was highly organised, and carried a full murder kit of rope, handcuffs and a full change of clothes to each murder. After killing his victim he cleaned the flat of any forensic eviden ...

At this time, he was considered an outcast at school, and sought to compensate for these feelings of isolation by joining the Cub Scouts. It was around this time that his sadistic and homicidal fantasies progressed to the point where he contemplated murdering strangers on the streets, tying and gagging those who resisted him. In one later psychiatric report, he was described as saying that he derived pleasure from the thought of his victims saying "if you are going to do i ...

Ted Bundy
Theodore Robert Bundy ( born Cowell; November 24, 1946 – January 24, 1989) was an American serial killer who kidnapped, raped and murdered numerous young women and girls during the 1970s and possibly earlier. After more than a decade of denials, he confessed to 30 murders committed in seven states between 1974 and 1978. His true victim total is unknown and likely significantly higher. Bundy was regarded as charismatic and handsome, and exploited this to win the trust of both his victims and society as a whole. He would typically approach his victims in public places, either feigning a physical impairment such as an injury, or impersonating an authority figure, before bludgeoning them into unconsciousness and taking them to secondary locations to be raped and strangled. Bundy often revisited his victims, grooming and performing sexual acts with the corpses until decomposition and destruction by wild animals made any further interactions impossible. He decapitated at l ...

Modus Operandi
A ''modus operandi'' (often shortened to M.O.) is someone's habits of working, particularly in the context of business or criminal investigations, but also more generally. It is a Latin phrase, approximately translated as "mode (or manner) of operating". Term The term is often used in police work when discussing crime and addressing the methods employed by criminals. It is also used in criminal profiling, where it can help in finding clues to the offender's psychology. It largely consists of examining the actions used by the individuals to execute the crime, prevent its detection and facilitate escape.Douglas, J. E. and A. W. Burgess, A. G. Burgess, R. K. Ressler. ''Crime classification manual'' (John Wiley & Sons, 2006) , p. 19-21. A suspect's ''modus operandi'' can assist in their identification, apprehension, or repression, and can also be used to determine links between crimes.Berg, B.L. ''Criminal Investigation'' (McGraw Hill, 2008) In business, ''modus operandi'' is used ...

Computer Database
In computing, a database is an organized collection of data stored and accessed electronically. Small databases can be stored on a file system, while large databases are hosted on computer clusters or cloud storage. The design of databases spans formal techniques and practical considerations, including data modeling, efficient data representation and storage, query languages, security and privacy of sensitive data, and distributed computing issues, including supporting concurrent access and fault tolerance. A database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an appl ...

Vi-CAP
The Violent Criminal Apprehension Program (ViCAP) is a unit of the United States Federal Bureau of Investigation responsible for the analysis of serial violent and sexual crimes, based in the Critical Incident Response Group's (CIRG) National Center for the Analysis of Violent Crime (NCAVC). ViCAP was created in 1985 by the FBI and based in Quantico, Virginia. Pierce Brooks was appointed as the first director, primarily because as a homicide detective in Los Angeles he had been the first to propose the idea. Brooks was inspired by the Harvey Glatman case he had worked on, in which he realized serial homicides could be linked by their signature aspects. Brooks would later obtain a $35,000 government grant to realize his idea. In 1982 he met with Robert Ressler to discuss the idea and was convinced by Ressler that ViCAP should be located at Quantico, as opposed to Lakewood where Brooks originally planned to have it housed. It is designed to track and correlate information o ...
