 History of the Baltimore Police Department’s Crime Laboratory

 

1948 - The history of the Baltimore Police Department’s Crime Laboratory began. It was built in a small room that was allocated for a crime laboratory as a part of the Detective Division, where then Sgt. Anthony F. Nelligan initiated the laundry and dry cleaning marks identification section, which he expanded to include handwriting and documents examination. He was joined by Sgt. Joseph Reitz who performed firearms examinations.

1951 - This one room soon proved too small for the growing crime laboratory and on October 26, 1951 the Crime Laboratory was formally established when Police Commissioner Beverly Ober promoted Lt. Anthony Nelligan, naming him as its head. The north wing of the 4th floor of the old headquarters building at Fallsway and Fayette, formally housing the printshop was set aside for this newly created department. By that time the Crime Laboratory included the specialties of Firearms, Chemical Tests, Laundry Marks, Documents, Photographic, Technical Arts, and Latent Fingerprints. 

1952 - In 1952 the Gunshop (now called the Armory) was established by Police Commissioner Beverly Ober to provide maintenance and repair of departmental weapons. Personnel included Sgt. Arthur W. Plummer and Officer J. W. Freeman. This unit was under the control of the Crime Laboratory, until moved to the Property Division in 1966.

1954 - The Mobile Unit was established in May of 1954 with four two-man teams whom for the first time responded to crime scenes and collected evidence including latent fingerprints. 

1955- In 1955 the eight men of the Mobile Unit responded to 2,372 crimes scenes. 

1959 - By 1959 the Crime Laboratory, still a part of the Detective Division, had expanded its specialties to include explosives; tool mark identification; spectroscopic examination; restoration of obliterated identification marks; identification of jeweler’s scratch marks; chemical development of latent prints; and shoe, footprint, and tire casts. 

1959 - Also in 1959, the Crime Laboratory implemented the use of the Breathalyzer to test persons arrested for driving under the influence. This function was a part of the Chemical Test Unit headed by Lt. Maurice A. Epple. 

The first commanding officer of the Crime Laboratory Lt Anthony Nelligan was promoted to Captain and eventually retired from the department on 11/9/67. Lt. Daniel Kennedy was designated as Officer in Charge of the Crime Laboratory in September 26,1968. The appointment of Police Commissioner Donald D. Pomerleau in 1966 brought forth a reorganization of the Police Department that included a reorganization and expansion of the Crime Laboratory. The Crime Laboratory became the Laboratory Division and was moved to the Services Bureau.

1966 - By this time the Crime Laboratory had expanded its specialties to include Polygraph Examinations and Identikit sketches.

1966 - In 1966, the Crime Laboratory also performed some unusual functions such as making call box keys, training riot squad members and loading ammunition.

1968 - in 1968, the U.S. Customs Service examined 7,000 items for the Baltimore Police Department. This grant was obtained and work on a new expanded laboratory began.

1969 - In March of 1969, the Police Commissioner made a proposal to obtain a grant that would facilitate the construction of a new Crime Laboratory on the 5th floor of the new headquarters building already under construction. This proposal included site preparation, scientific equipment and furniture. This proposal also was the foundation for the Crime Laboratory to perform Controlled Dangerous Substance analyses, which at that time were being done at the U.S. Customs Service Chemical Laboratory.

1970 - the department started replacing sworn officers with civilian employees to return officers to the street.

1972 - The Crime Laboratory moved into its new quarters in September of 1972. Director Thomas M. Muller was named by Police Commissioner Donald D. Pomerleau in October of 1970. Starting in August of 1970 the department began to civilianize the Crime Laboratory, replacing sworn officers with civilian employees to return officers to the street.

Director Thomas Muller retired in 1996 and was replaced by Acting Director Sharon Talmadge until the appointment of Director Edgar F. Koch, Sr. in January of 1997. Since that time the Crime Laboratory has expanded its services and staff while limited to the 5th floor location it moved into in 1972. The Laboratory Division, now a part of the Criminal Investigation Bureau, moved to new facilities on the 9th and 10th floors of the renovated headquarters building starting in September, 1999.

1977 - Hair comparison-by-comparison microscopy began in 1977.

1980 - The Drug Analysis Unit began using automation to expedite drug analysis on the Gas Chromatographs and Mass Spectrometers in 1980.

R
eplacing sworn officers with civilian employees to return officers to the street, which enabled the department to use computerized fingerprint searches to assist examiners with respondents for potential latent print identifications.

1988 - In 1988 the Laboratory Division began the use of Lasers for the detection of latent prints and body fluids at crime scenes and on evidence.

1991 - In the Firearms Unit, Drug fire was obtained in 1991.

1991 - This system was replaced in 1991 with Morpho with new and improved capabilities. Fiber analysis and comparison using MICROVIS (visible light microspectrophotometry) and FTIR (Fourier transform infrared spectroscopy) began in 1988.

1991 - Gunshot Residue Analysis (GSR) using Scanning Electron Microscopy began in 1991.

The Firearms Unit was the pilot city for ATF’s batch transfer system, allowing electronic transfer of firearms information for tracing. DNA analysis, using outside vendors began in 1987 completely replacing conventional serology in 1996.

1993
- The Breathalyzer was replaced with a computerized version, the Intoximeter in 1993.


1994
- The Polygraph Unit began using a computerized polygraph instrument for conducting polygraph examinations in 1994.

1
996 - Identikit sketches were performed by the Mobile Unit until 1996 when a computerized version E-Fit was adopted by the department and became used by the detectives who were investigating the case.

1996
- The Mobile Unit began using CAD aided design programs to do computerized crime scene sketches in 1996.

1997 - This system allows the Firearms Examiner to store thousands of images of fired cartridge cases for comparison at a computer station. Its bullet counterpart, Bulletproof, was obtained in 1997.

1999 - In 1999, the Laboratory Division received a grant from the National Institute of Justice (NIJ) for a DNA facility housed in the newly renovated 0th floor of the Headquarters building. 

2000 - The Mobile Unit moved their vehicle processing operation to the new processing bays in the renovated south drive of the headquarters building. With the reorganization of the department in 2000 the Laboratory became a Section. Many major scientific advances have been incorporated into the Crime Laboratory’s services in the last three decades.

2002 - In 2002, the Laboratory installed a Laboratory Information Management System (LIMS) for the Drug Analysis Unit, which creates electronic reports with electronic signatures. The Baltimore Police Department’s Laboratory Section provides forensic services to many law enforcement agencies within and outside of the City of Baltimore. The Laboratory Section continues to be dedicated to providing the highest quality, most accurate and efficient forensic support available to the Police Department, the criminal justice system and the citizens of Baltimore.

FORENSIC SCIENCE

Forensic science involves the application of hard science and technology to the solution and prosecution of crime. Based upon the underlying principle that the criminal leaves part of himself at the scene, and takes part of the crime site with him, forensic science includes the identification and analysis of physical evidence in the form of impressions, trace evidence, and weaponry. Since physical evidence needs to be interpreted by an expert, it is, by definition, circumstantial. Fields of forensic science include: fingerprint technology, scientific lie detection, firearms identification, questioned documents, and forensic pathology, toxicology, chemistry, botany, entomology, anthropology, geology, and serology (DNA).

FINGERPRINTS

In 1901, Scotland Yard became the first law enforcement agency in the work to routinely fingerprint its arrestees. Fingerprint identification came to America in 1904 when the St. Louis Police Department established its fingerprint bureau. Before fingerprinting, arrestees were identified by sets of eleven body measurements, a system created in the 1870's by the Frenchman, Alphonse Bertillon. By 1914, the year of Bertillon's death, fingerprinting had replaced anthropometry or Bertillonage in every country except America where, in many jurisdictions, the outdated system was used until the 1920's. Because a set of inked, rolled-on fingerprint impressions can be classified or grouped into ridge patterns -- loops, whorls, and arches -- arrestees who use aliases can be physically identified. Through centralized fingerprint repositories comprised of millions of fingerprint cards, individual arrest histories can be maintained on habitual offenders. These fingerprint collections are also responsible for the apprehension, every year, of thousands of fugitives. For example, a suspect wanted in for murder in Seattle who is arrested for burglary in Tampa, after his prints are matched with the Seattle fingerprint card, can be held in Tampa for the authorities who have been looking for him. Beyond the use of fingerprinting to maintain crime records and to catch fugitives, crime scene finger marks -- so-called latent fingerprints -- constitute one of the most common methods of linking suspects to the sites of their crimes. While latents can be made visible by various chemicals, iodine fuming, and laser technology, the most popular method of identifying and preserving fingerprints, particularly on hard surfaces, involves the use of fingerprint powder and special lifting tape. Crime scene latents can now be fed into a massive computer -- the Automated Fingerprint Identification System (AFIS) -- and matched with a single rolled-on impression in the computer. Identifying unknown crime scene latents in this way is one of the few instances where forensic science can solve and prove the case. Perhaps the three most significant developments in the history of law enforcement and criminal investigation include fingerprint classification, AFIS, and the cutting edge science of DNA "fingerprinting."

FORENSIC FIREARMS IDENTIFICATION

In the past called forensic ballistics, this forensic science concerns itself with the comparison and identification of crime scene bullets and shell casing firing pin impressions with the marks on test-fired rounds in the crime lab. If the marks on the bullet made by the test gun barrel are identical to the striations (rifling scratches) on the crime scene bullet, or the firing pin impressions are the same, the crime scene weapon has been identified. The science is grounded on the principal that no two guns will leave the same marks on the ammunition. Bullet striations and firing pin impressions are unique as a person's fingerprints. Firearms identification also involves restoring filed off serial numbers, retracing projectile flights, identifying the various types of bullet wounds, and determining the range of close range shots through powder stain patterns on the target. Firearms identification experts apply the sciences of metallurgy, chemistry (gunshot residue analysis), microscopy, and ballistics. A knowledge of the gun smith trade is also useful. Like document examiners, forensic firearms experts are trained on-the-job in crime laboratories.

FORENSIC LIE DETECTION: THE POLYGRAPH TECHNIQUE

In order for a polygraph result to be accurate, the instrument must be in good working order; the examiner properly trained and experienced in question formulation and line chart interpretation; and the subject (examinee) a willing participant in the process. Not everyone is suited for polygraph testing. People who are ill, on drugs or alcohol, extremely obese, retarded, or mentally unbalanced should not be tested. The more serious the crime, the more reliable the results. It is important that the examiner be familiar with the details of the crime in question, otherwise he or she may not ask the most appropriate questions. The polygraph instrument measures and records the examinee's involuntary, physiological (bodily) responses to a set of ten yes or no questions. The examinee will know in advance what questions will be asked. Based upon changes in the examinee's blood pressure, heart rate, breathing patterns, and galvanic skin response, the examiner will draw conclusions whether, in response to the payload question - did you kill your uncle? - the subject is lying or telling the truth. Polygraph examiners are not recognized by the criminal courts as expert witnesses, therefore polygraph results are not admissible as evidence in criminal cases. A federal law passed in 1988 prohibits the use of the polygraph technique as a private sector pre-employment screening device. Most law enforcement agencies at all levels of government do test job candidates. It is a widely used investigative tool, and there are about a dozen polygraph schools in the United States.

FORENSIC DOCUMENT EXAMINATION

Also referred to as questioned document examination, this branch of forensic science includes the identification of handwriting paper, ink, typewriting, and writing instruments. Ninety percent of a document examiner's work has to do with the comparison of known handwriting samples with the questioned writing - a bank robbery note, a ransom document, the address on a mail bomb, a threatening letter, and signatures in wills, insurance policies and contracts that might have been forged. Examiners utilize chemistry, specialized photography, and microscopy in their work. A few specialize in the restoration of charred and burned documents. As forensic experts, they are often called to court as expert witnesses in civil and criminal cases. There are no schools for this kind of work, all education and training comes on-the-job in federal, state, county or big city crime laboratories.
