State Supreme Courts require a minimum threshold of reliability and accepta
nce in the scientific community for all medical and similar evidence to be
admitted at trial. In Florida and some other states, the courts adhere to w
hat is known as the Frye standard, whereas in most states and in Federal Co
urts, it is the so-called Daubert standard. The jurisdiction of the present
case is Hillsborough County (Tampa), Florida. Forensic pathologists seldom
, if ever, are requested to participate in such hearings, unlike their toxi
cological and basic science colleagues who are more involved in research me
thodology and technical procedures.
The burden is on the proponent of the evidence to prove the general accepta
nce of both the underlying scientific principle of the test and procedures
used to apply that principle to the facts of the case at hand. The trial ju
dge has the sole discretion to determine this question and general acceptan
ce must be established by a preponderance of the evidence.
The authors describe in detail a hearing in a case in which they were all i
nvolved. One author (WQS) had researched and documented the original scient
ific methodology in the Literature. The situation involved a car and tracto
r trailer crash with the two occupants of the car dying of multiple trauma,
whereas the truck driver was not injured. Autopsy of the auto driver revea
led multiple injuries with exsanguination, and only vitreous humor and live
r tissue, but not blood, were tested for ethyl alcohol. The estate of the d
river of the automobile brought suit against the owner of the trucking comp
any for wrongful death. The plaintiff requested a Frye hearing to question
the reliability of testing other body specimens to translate to probable bl
ood alcohol level. The testimony, submitted documents, and eventual decisio
n by the judge are discussed.
