The Crime Unit consists of 2 crime scene technicians and 2 Police Service Aides.
The Crime Scene Unit is responsible for the documentation of major crime scenes including homicides, suicides, sexual batteries, armed robberies, shootings and suspicious deaths. Members of the Crime Scene Unit provide forensic training to numerous police institutes in the area and are recognized as court-declared experts in several judicial districts in various forensic fields.
Using state-of-the-art video and still photography equipment, team members record details of a scene for future investigation, analysis and preparation for court review. The unit also supervises the proper collection of evidence, latent fingerprint processing and other evidentiary duties relating to major cases. Available to respond 24/7, the unit is outfitted with high-tech investigative equipment to assist in providing mobile investigations and support to detectives while in the field.
Each Crime Scene technician is issued an identical crime scene van fully equipped with the latest Nikon photography equipment, video camcorders, evidence detection/collection equipment as well as level ?B? biohazardous protection gear including three different types of respirators. Recognized for performing one of the most hazardous jobs in law enforcement, crime scene personnel are closely monitored through semi-annual medical testing for their safety.
The Sunrise Police Department Crime Laboratory works in tandem with the Crime Scene Unit and is divided into five areas of forensic expertise:
The Chemistry Unit identifies controlled substances in seized drugs and narcotics utilizing Gas Chromatograph/Mass Spectrometers (GC/MS), a gas chromatograph/Fourier transform-infrared spectrometer and an ultraviolet spectrophotometer. The Trace Analysis Unit deals with the analysis of evidence such as paints, fibers, headlamp filaments, fracture patterns, and tear patterns. This type of evidence is often microscopic in size. The section is equipped with sophisticated analytical instrumentation including a pyrolysis-gas chromatograph, a Fourier Transform Infrared Spectrometer Microscope, a Visible Light Microspectrophotometer, and a Polarized Light Comparison Microscope. Fire debris evidence is analyzed by GC/MS.
Identifies and analyzes body fluid evidence and prepares DNA profiles for matching to local, state and national databases. The section features state of the art equipment that includes: a robot for DNA extraction and purification; and an automated DNA quantifier; and four genetic analyzers used for separating the DNA fragments and obtaining profiles.
Handles firearms, tool marks, audio/visual analysis and questioned documents. The Firearms Unit deals with analyses involving the comparison of projectiles and cartridge cases found at a scene to submitted firearms. Tool mark analysis associates striations left by a tool with a suspect tool. The Audio/Video Analysis Unit provides investigators and prosecutors with the best possible images and sound from evidentiary tapes. The Questioned Documents Unit deals with analyses concerning handwriting, typewriting and document alteration, including counterfeiting and forgeries.
Latent Print Identification
Involves the evaluation and comparison of latent prints recovered from crime scenes. The identification and elimination of latent prints associated with a crime scene is accomplished through comparisons of latent fingerprints to the rolled standards of known individuals. Non-suspect latent print cases are searched against a database of persons previously arrested through the Automated Fingerprint Identification System (AFIS).
Automated Fingerprint Identification System (AFIS)
Classifies "ten print" cards (fingerprint cards with prints from both hands) and verifies identification. AFIS Latent Examiners evaluate and compare latent prints recovered from crime scenes with known standards. Each year, the AFIS Unit enters approximately 40,000 ten prints into a database of more than 220,000 records and 1,000 latent prints to a database of 11,000 unsolved latent records for use by all Broward County police agencies.
