Prelog FAQ’s:

  1. I am on the last screen and I cannot see any selections for analysis type.
    • Make sure that you have selected a case type in the case info screen.
  2. Why does my Prelog sheet say Submission 2 (or 3 or 4) when this is my first and/or only submission?
    1. If you went to the submission page more than once, you must hit edit to see and add to your current submission.  Clicking “Add” makes a new submission.
    2. Someone else from your agency or task force has Prelogged evidence before you on the same case.
  3. I have multiple items on the same case that were collected at the same time from the same person.  Do I make each a separate submission, or put them on the same submission.
    • Put all of the items on the same submission.
  4. I have a bag with two items inside the sealed bag.  Do I put one item or two on the Prelog?
    • One item.  Each package is an item, not the items inside the package.  The lab will identify these upon examination.

Internship Program and Shadow Experiences

The Westchester County Forensic Laboratory is pleased to announce that our Forensic Internship/Shadowing program has been restarted after a hiatus due to COVID-19. The goal of our program is to provide an introduction to forensic cases in a working laboratory, to students interested in pursuing a career in forensic science.

Our Internship Program is designed to meet the needs of college students in Forensic Science majors that require an internship as part of their core curriculum. Forensic Science students who do not require an internship and students majoring in related laboratory sciences will also be considered based on availability.

Our Shadow opportunity is a short term experience designed for students at the High School level or above to spend time observing the analysis of physical evidence in the Forensic Biology (DNA), Trace Evidence, Forensic Chemistry, and Forensic Imaging sections of the Division of Forensic Science Services. High School students will only be offered the shadow experience option.

You will be required to submit an elimination buccal sample if you are accepted for an internship or a shadow experience. This is required for you to be able to observe analysts during the examination process and the DNA analysis of evidence. It is to ensure that a DNA profile obtained from the evidence is from the biological/trace material on the evidence and not from anyone present in the examination room or DNA laboratories. A profile from your buccal sample will be generated and this profile will be added to the laboratory’s staff database. Your profile will not be uploaded to any other databases or given to any outside agencies (law enforcement, district attorney’s office, etc.). Your profile will be marked for deletion 6 months after your last day here. You can be notified once the deletion has taken place upon request.

In addition, you will also be required to sign a Confidentiality & Conflict of Interest Policy Agreement.

If you have any questions regarding the buccal sample and/or the agreement, please send them along with your application.

College Students

Applicants must either attend a college/university within the Tri-State area or reside in NYS, and be in an undergraduate program. Westchester County residents will be considered before non-Westchester County residents. In general, students must be enrolled in school during the term of the internship, should be in at least their Junior year when applying, and must be in good academic standing in a Forensic Science program or a closely related laboratory sciences program.

The Forensic laboratory distributes applications for internships to college students twice each year to be considered for winter intersession and summer breaks.  If you are interested in an internship, you may contact us via email at finc@westchestercountyny.gov.  We will honor requests to apply for winter intersession internships starting September 1st each year.  We will honor requests to apply for summer internships starting March 1st each year.  Due to the volume of submitted applications, the request timeframe will vary.  If you have any further questions or require additional information regarding the internship program, you may contact us at finc@westchestercountyny.gov  and your email will be answered as soon as possible.

There are two terms in which you can carry out your internship: winter intersession, and the summer.
As an intern, you may observe the analysis of physical evidence in the following areas:
• Forensic Biology (DNA)
• Trace Evidence
• Forensic Chemistry
• Forensic Imaging

Research projects in these areas are not guaranteed. If a hands-on project is desired, please indicate that in your interest email.

High School Students

School advisors may contact the laboratory at finc@westchestercountyny.gov if there are any questions or if additional information is required regarding the shadow experience.

Tours

The Division of Forensic Science Services offers tours of the county's Forensic laboratory. These tours are typically offered to area colleges and Westchester County high schools. Please be aware that due to staffing and casework responsibilities, the laboratory must limit the number of tours and the number of individuals in each tour.  

To start the process of requesting a tour, email finc@westchestercountyNY.gov. Please include the following in your email: preferred date(s) and time(s), your institution name and address, the total amount of individuals you are requesting attend the tour, and the mode of transportation (for parking needs). A coordinator will respond to your request.

Analysts processing a mock crime scene

The Forensic Science Laboratory routinely conducts training sessions for local law enforcement agencies in how to apply state of the art technologies to the examination of evidence and crime scenes.

Specialized workshops cover topics such as DNA laboratory capabilities, the use of CODIS in investigations, collection and packaging of physical evidence, impression evidence, crime scene photography, arson evidence collection, and audio, video, and image analysis.

In addition to these laboratory initiated programs, our laboratory staff provides training to the WCPD Academy new recruit school, and Zone 3 training sessions.

Blood and Urine extraction for drug testing

Toxicology is the study of harmful effects of chemicals on biological systems. It is a branch of pharmacology that incorporates many areas of knowledge including pharmacology, analytical and organic chemistry, physiology, and pathology. 

The Toxicology Laboratory analyzes biological specimens for the presence of alcohol, drugs and other toxic compounds as a part of postmortem medicolegal investigations of the Westchester County Medical Examiner's Office. The Medical Examiner’s Office uses information generated by the toxicology laboratory when determining the manner and cause of death of an individual. Through the application of toxicological and pharmacological principles, the toxicologists interpret the test results in order to assist with the formation of conclusions regarding the circumstances of the death. 

The laboratory provides human performance testing services to local, county and state law enforcement agencies within the county associated with the charges of driving while under the influence of alcohol (DWI) and driving while under the influence of drugs (DUID) arrests. Human performance testing refers to the testing of individuals for any impairment of their ability to operate motor vehicles due to the presence of drugs or other performance impairing substances. Laboratory testing results may determine impairment due to alcohol or confirm impairment by other drugs and substances.

Laboratory personnel also provide human performance testing consultations and testimony for breath alcohol testing conducted in the county by law enforcement agencies. 

On occasion, toxicological investigations are conducted for county health facilities.
