the knife is wrapped in a white towel
with the towel in the knife cake with
dried blood codes of DNA binds together
the hard facts can lead to a legal
separation as well Michael you are not
welcome to watchmojo.com with both
victims was found in Simpsons Bronco in
this installment we’re counting down our
picks for the five most interesting
facts you probably didn’t know about DNA
evidence number five
DNA was first used for a criminal
investigation in 1986 both genetic
fingerprinting and DNA profiling were
theories rather than accepted legal
practices and due to the innovations of
Professor Alec Jeffrey’s DNA first
assisted criminal prosecutors in 1986
after the rape and murder of two English
women a teenager with learning
disabilities became the prime suspect
but with Jeffrey’s discovery of how to
separate sperm and vaginal cells the
evidence linked another man to the crime
and so after a long history of Flash and
women it was revealed that Colin
pitchforks crimes had taken a more
violent turn which ultimately led to a
life sentence in prison by convicting
pitchfork and clearing Buckland of these
crimes this case was both the first
exoneration and conviction via DNA
fingerprinting number four thanks to TV
jurors expect DNA evidence
given the popularity of the CSI
franchise and earlier the media circus
that was the OJ Simpson trial DNA
evidence has become a standard
expectation for modern jurors this
expectation is part of what’s known as
the CSI effect one of the largest
studies on this suppose that effect
found that 73 percent of prospective
jurors expect to see DNA evidence
presented in rape cases while 22 percent
expect to see it in every criminal case
eye swab the blood and sent a sample to
the DNA lab the lab technician ran a
sample through CODIS the DNA sample was
a match to a recent rape and homicide
victim in other words the general public
now understands the power of DNA and the
creative ways in which it can be
acquired fans of crime procedurals may
think they have a better understanding
of how DNA works but those shows are
often criticized for being inaccurate in
their science shows only at our law and
laser ablation takes like six yeah but
when they cut it together it’ll only
take 30 seconds so then the question
becomes does the jurors perceived
understanding of forensics have an
impact on their decision making research
on the topic seems to say thankfully
that it does not so much for that CSI
effect number three please collect DNA
without your knowledge
police may collect DNA without your
knowledge
while covert operations sometimes reveal
police entrapment American criminal
investigators may legally collect DNA
without a subjects knowledge this might
take the form of a police officer
telling a detainee to spit out their gum
or innocently offering a glass of water
only to collect that gum or that
drinking glass to obtain a DNA sample
in 1988 the Supreme Court of the u.s.
determined that evidence can be
collected from garbage left on the curb
in front of a home of course
cops don’t need to steal your used
hankies to collect DNA a 2013 Supreme
Court ruling affirmed that u.s. police
officers can collect a cheek swab from
an arrestee just as they’d collect
fingerprints it’s just as cheek swab it
won’t take but a second and over in the
United Kingdom investigators may also
collect public samples however private
investigators may not legally employ
such tactics due to the human tissues
Act of 2004 number two it’s possible to
have two sets of DNA in the early stages
of pregnancy a fetus can be absorbed by
its twin which can occasionally lead to
a second set of DNA being present within
the surviving twin as many of you know I
ate my twin sister in utero so on my
birthday I try to remember I’m a winner
having two separate sets of DNA is
called chimeras ‘m strangely enough this
means the paternity and maternity tests
have yielded some inexplicable results
causing a little bit of stress for those
just learning of their unborn twin one
chimera
Lydia Fairchild nearly lost custody of
her children after DNA tests indicated
she was not their mother in 2014 a 34
year old Washington man also learned
that he was genetically not the father
of his own children given that he was
carrying DNA of his unborn twin and so
DNA evidence not only assists in
real-life courtroom dramas but sometimes
creates some unexpected family dramas as
well you are not
number one a DNA mistake created a
fictitious serial killer
from 1993 to 2009 a female serial killer
left DNA at murder scenes in Germany
Austria and France this unidentified
woman became known as the Phantom of
Heilbronn however it turns out that she
didn’t actually exist the so-called
woman without a face was created due to
contaminated cotton swabs apparently all
the law-enforcement agencies involved
had been ordering cotton swabs from the
same Factory and apparently one of the
female factory workers had gotten some
of her DNA on them and so truth and
justice evaded the grieving families of
those murder victims while investigators
hunted down a fabricated serial killer
all because of one procedural error this
never would have happened if European
forensics experts watched more CSI looks
like something caught her so do you
think watching police procedurals has
made you a better crime fighter nail
polish diamond particles maybe she was
giving herself a mani and pedi with
Livius oh and do you know anyone who has
been legally tormented by an unborn twin
