The Northern Colorado Regional Forensic Laboratory

The Northern Colorado Regional Forensic LaboratoryThe Northern Colorado Regional Forensic Laboratory (NCRFL) provides forensic science services to the Weld County Sheriff's Office, Larimer County Sheriff's Office, the Greeley Police Department, the Fort Collins Police services and the Loveland Police Department. In addition, the Colorado Bureau of Investigation is a full participant in the laboratory and offers its services to any law enforcement agency within the Northern Colorado Region as well as serving as the quality oversight agency for the regional lab. This regional lab has staff provided by all 6 agencies listed above working in the following forensic disciplines: Digital & Multimedia Evidence (computers/cell phones, audio analysis and video analysis), Latent Prints, Impression Evidence (shoe and tire track comparisons), Firearms/Tool marks (to include serial number restoration and distance determination), Drug Chemistry Analysis, and Forensic Biology.

The services provided by the highly trained personnel in the NCRFL are as comprehensive in the specialty areas described above as in larger labs. The goal of the lab is to provide quality services that meet the needs of the criminal justice system in the northern Colorado region. Laboratory examinations and analysis carried out with integrity and technical competence will help exonerate the innocent as well as help convict the guilty.


Digital and multimedia evidence

Digital & multimedia evidence is a forensic service where the lab has observed a continuing increase in the demand for services. The discipline encompasses two basic areas; computer forensics and audio/video analysis. Examiners work to first to collect the digital data/images that can be found in various digital devices, to include smart phones, computers, GPS, and surveillance systems. Secondly, the examiners employ various technologies, both software and hardware based, to interpret the data collected to provide useful information to assist the submitting agency in their investigations.


Latent Print table

Fingerprint comparison is one of the oldest recognized forensic specialties. However, before a comparison can be made, fingerprints must be found, revealed, and documented. Many specialized methods have been developed to reveal fingerprints on the many surfaces needing fingerprint processing. In addition to the fingerprint powders that are available, there are many chemical methods used to treat surfaces. Most of these chemical methods are used in conjunction with an "alternate light source" to enhance the detail and contrast of a fingerprint on a surface. Prints revealed with powders are "lifted" with tape and placed on a contrasting background for examination. Prints revealed using other methods must be photographed to scale, and the photos used by the examiner for comparison. A fingerprint comparison expert must then judge the quality and detail in an unknown print before a comparison can be made. Using high-resolution digital photography and image enhancement software, an examiner can digitally "remove" things like repeating patterns or interfering colors on the surface of the print and then the fingerprint is photographed to produce a better quality image.”


Forensic biology involves the identification involves the identification of biological fluids found on items of evidence submitted to the laboratory. The identification process may involve only a presumptive test, or it may be followed up with a confirmatory test. There may be cellular material containing DNA not related to a bodily fluid that can be collected for further analysis. All of this work is performed in the screening section of forensic biology. DNA testing follows the screening process on those items determined to be of value for further testing to identify the soured of a stain or cellular material deposited at the scene. Once a DNA profile is developed it can be compared to know DNA profiles provided for comparison.


drug chemistry analysis services

The drug chemistry analysis services involve the use infrared spectroscopy (I.R.) and gas chromatography/mass spectroscopy (GC/MS), as well as microscopic examinations and photography where appropriate. The majority of cases requiring chemical analysis involve identifying controlled substances (illegal drugs). Although this is our primary duty, we can also analyze items to identify their composition.


Firearms Examining equipment

Firearms examiners employ forensic analysis on firearms, ammunition, ammunition components, tools, tool marks, and other tool related evidence. Examiners may also perform examinations on clothing, bedding and other surfaces for the presence of gunshot residues or powder patterns, muzzle to target distances determinations, chemical restoration of obliterated serial numbers, cartridge case ejections and trajectory evaluations. Examiners may respond to scenes to assist in the documentation and collection of evidence, chemical testing for trace metals, reconstruction and diagramming of shooting events, and providing technical assistance to investigators.


Northern Colorado Regional Forensic LaboratoryShoe and tire track impression evidence is commonly found at crime scenes. Crime scene investigators will document these impressions through photography and casting or lifting techniques. It is the job of the shoe and tire track examiners in the lab to compare shoes or tires submitted to these photographs, castings and lifts to determine if they made, could have made, or did not make the crime scene impressions.


While the NCRFL does not respond to crime scene as an agency the staff within the laboratory may be assigned to provide that service for their agency. If called upon for expert assistance in a given discipline the laboratory may be capable of providing staff to assist the agency's deputies, officers, and/or investigators at major crime scenes. They may assist in the diagramming of crime scenes, the processing of evidence if needed at the scene, and the correct accounting for all the collected evidence. The quality of their work and their testimony in court is crucial to the admissibility of the gathered evidence.
