Sex marker and 13 other markers

Identified using Short Tandem Repeats (STR)

Compare questioned stain profiles to suspect profiles

If a match is obtained, calculate statistical probability

Statistical probabilities can range from 1 in tens of millions to 1 in quintillions (1 in 1,000,000,000,000,000)

Latent PrintsLatent Prints

Questioned impressions from crime scenes can be photographed, lifted, or cast with dental stone to compare to suspect shoes or tires

Footwear impressions can be as individual as a fingerprint

Tires undergo a unique transformations as they wear down

Accidental scratches, nicks, and cuts are left on the tires which also may be unique

Comparison of tread designs, wear patterns and unique characteristics can lead to a positive identification

Computerized system capable of reading, classifying, matching and storing fingerprints

Quality latent fingerprints are entered into the AFIS

Searched against all fingerprint records in the state

Possible hits are determined by the computer and verified by a Latent Print examiner

If no hit is made against the Florida Database, the print can be searched nationally using IAFIS

Evidence can associate a person with a place oranother person

Examines trace evidence that is sometimes no larger than the

numbers in a date on a penny

MicroanalysisMicroanalysisGlass, Fracture Match, Bulb FilamentsGlass, Fracture Match, Bulb Filaments

Comparisons may include:- Glass from a suspects clothes, compared with broken glass from the crime scene

- Cut, broken or torn objects to determine if they were at one time part of the same object

- Light bulb filaments from a car in a hit and run can be examined to determine if the lights were on at the time of the accident

MicroanalysisMicroanalysis

Fibers can be transferred between the clothing of two individuals involved in a crime.

Paint found on the clothing of a hit and run can be compared to a suspects vehicle OR analyzed to determine makes/models of suspect cars

Fibers are compared against standards from clothes for possible match

Analyzes samples of blood and urine in order to detect alcohol and other impairing drugs or chemicals

ToxicologyToxicology

The majority of case submissions to the Toxicology section are DUI cases

In Florida, blood alcohol concentration of 0.08 percent or higher is considered presumptive for impaired driving

Toxicologists can do “back extrapolations” to determine a person’s alcohol level at the time of the offense

In DUI cases, blood and urine samples may also be analyzed for the presence of Controlled Substances

Analyzes cases involving suspected drug facilitated sexual assault (DFSA)
