Part of a Wanted Poster for Willie Sloans, 1929 (Series 253)
When it comes to learning more about the history of Westchester County’s “criminal element,” the Westchester County Archives is a good place to start. As the repository for the historical records of the County’s District Attorney’s office, and the Departments of Correction and Public Safety, there is much at the Archives to learn about those who have broken the law and those who have brought them to justice.

Whether you are a social historian documenting trends in crime or social relations in the early twentieth century, a student looking for an interesting research topic, or a family historian looking for the family black sheep, the “Crime and Punishment” collections held by the Westchester County Archives are a good place to start. With over 200 cubic feet of District Attorney Case Files and 37 Jail Blotter Books, there are many fascinating stories just waiting to be discovered.

District Attorney Case Files

The most extensive records in this group are the District Attorney Case Files, 1892-1949 (bulk 1906-1949) (Series 253). These files provide fascinating insights into the functioning of an active prosecutor’s office during the first half of the twentieth century. Although some case files may be razor-thin and contain only a True Bill (indictment) against the defendant, others burst at the seams with extensive case documentation ranging from witness statements, correspondence concerning the case and the defendant(s), and a wide variety of documentation used as trial evidence or to investigate the crime. Some case files even include photographs of the defendants, or, particularly when a murder is involved, the crime scene itself. 

For an overview of the District Attorney Case Files, read “Preserving Law and Order.” (Note: This article first appeared in the Fall 2010 issue of "New York Archives" magazine, a benefit of membership in the Archives Partnership Trust. It is reposted here with permission from the Trust.) 

To view a small sample of the types of records found in these case files see our digital collection "District Attorney Case Files: Obscure, Noteworthy and Notorious".

An extremely detailed index for over 10,000 DA Case Files processed by Archives’ staff and volunteers is available in-house at the Archives. This covers all records in the collection up through 1925, and part of 1928 through 1930 (work is still being done to process case files for the years 1926, 1927 and part of 1928). In addition to recording the names of the defendant(s) in each case, the crime committed, year of the case, and the town in which it was committed, detailed notes have also been made in the index about the specifics of the crime and, in some cases, the specific records available in the case file. With this wealth of detail, this database can help researchers quickly identify defendants and cases of interest. It may also suggest research topics, as great efforts have been made to identify records on such socially significant subjects, such as:The front of Herman Brown's Bertillon card (Series 253)

  • organized crime in early Westchester (including the “Black Hand”)
  • the prevailing attitudes of the day towards women, immigrants, different religious and ethnic groups, and racial minorities by law enforcement, prosecutors, and the community at large
  • the evolving nature of criminal law over the years, from the prosecution of an individual for distributing “obscene literature” for pamphlets entitled “Advice for Women” and the “Book of Health and Knowledge,” to the illegalness of providing entertainment on Sundays, the breaking of Sunday sale of liquor laws, the defiance of Prohibition, and to the rise of crimes involving automobiles such as driving while impaired and leaving the scene of an accident
  • the history of law enforcement practices, from reports submitted by Pinkerton detectives to the photographs and body measurements collected about prisoners on Bertillion cards, which would later be replaced by the use of fingerprinting

The Archives’ DA Case File Index can also be used to direct researchers to those files which contain, among other things:

  • the most “supplemental materials,” such as photographs, letters, postcards, newspaper clippings, and exhibit materials (from slot machine plugs, naturalization and marriage certificates, address books, posters, train schedules, and cuff links all the way up to guns and knives)
  • materials that discuss conditions at the various New York State prisons that Westchester criminals were sent to, including Sing Sing, Elmira Reformatory, Bedford Reformatory, Matteawan (Dutchess County), and Dannemora (Clinton County)
  • trial testimony, detailed witness statements, coroner’s reports, and even “ante-mortem” statements by those victims of crimes expected to eventually succumb to their wounds

Department of Correction Jail Blotter Books

From the County’s earliest days, the Sheriff has been responsible for running the County Jail and housing prisoners awaiting trial or pre-sentencing. This role was assumed by the Westchester County Department of Correction in 1969, as well as responsibility for the County Penitentiary, which was established in 1916 under the Department of Welfare (now known as the Department of Social Services) for housing sentenced misdemeanants serving sentences of a year or less.

Sample of a Jail Blotter book from 1919 (Series 310)The Westchester County Archives holds the Jail Blotter Books (Series 310) maintained by the sheriffs of Westchester County and then the Department of Correction from 1903 through 1973. These ledgers provide extensive details about those incarcerated in the jail for crimes ranging from vagrancy to homicide. The information available about each inmate includes the facts about their imprisonment – such as the date they were admitted to the jail, the crime charged with, date of discharge, and number of days confined, as well as demographic information – such as age, gender, race, place of birth, marital status, level of education, religion, and occupation. The latter demographic information makes these Blotter Books valuable resources in studying the make-up of the Westchester jail population over time, while the crime statistics make for an interesting review of the types of crimes being committed over the years.

Indexing of the Jail Blotter Books was begun in 2013 from the last year available to researchers (1938) and is being done in reverse chronological order. It is the hope of the Archives to eventually create a full index to the individuals listed in these Blotter Books, particularly for the years 1903-1913, for which there is no other index. For the years 1914-1974 (with some gaps in the 1940s) the Indexes to Jail Blotter Books (Series 311) can be used to look up the complete jail blotter records for individual inmates.

Restrictions on Using Jail Blotter Books and Indexes to Jail Blotter Books

Access to Jail Blotter Books and Indexes to Jail Blotter Books that are less than 75 years old is restricted. Searches for individual names can be made in these records but will be done only by Archives’ staff. For additional information about these restrictions, please contact the Archives.

Additional Department of Correction Records

Documenting the work of the Department of Correction is not limited to lists of those who were housed within the County Jail. It is also important to understand some of the issues faced by those inmates as well as those who guard them. As part of this effort, the Archives is developing a Department of Correction Historical Records Collection, 1981, 1995 (Series 309) and also has a Department of Correction Scrapbook, 1986-1989 (Series 307).

Department of Public Safety Records

Before criminals are brought to trial or incarcerated for their crimes, it is the police who investigate and arrest the criminals, and even prevent crimes from occurring. The Westchester County Department of Public Safety was created on July 1, 1979, through a merger of the Westchester County Sheriff’s Department and the Westchester County Parkway Police.

The Westchester County Archives documents the work of these law enforcement professionals through its “In Memoriam” Collection, 1792, 1925-1985 (Series 285), which memorializes the seventeen Westchester County lawmen who died while on active duty. In addition, the Sheriff Darius Lyon Receipt Book, 1865-1871, 1888 (Series 286) (Westchester County Sheriff from 1865-1868) documents some of the expenses incurred by a County Sheriff in the nineteenth century.
