during a romantic dinner,
갑자기 이런 생각 드신 적 있나요?
내 지문이 묻었어.'
all over my wine glass."
when you visit a friend,
여러분이 만진 모든 곳에
on every surface that you touch?
걱정스러웠던 적이 있나요?
to sit without touching anything?
앉으려고 신경을 썼나요?
the power of fingerprints, too.
지문의 힘을 과소평가하죠.
the twisted parting of lines
꼬여있고 갈라진 선을
an entire world of information
종종 감춰져 있는
are made up of molecules
분자로 만들어집니다.
in very different amounts ...
다양한 양의 땀 분자가 있죠.
땀으로 배출되는 것입니다.
and then we sweat out
묻어 있는 분자가 있습니다.
our fingertips with
물질의 분자죠.
like blood, paint, grease,
물질도 있습니다.
the storytellers of who we are
무엇을 해왔는지 말해주죠.
the right technology to make them talk.
정확한 기술이 필요할 뿐이죠.
of unthinkable capabilities.
여행을 떠나보도록 하죠.
in the woods three days later,
그녀의 시신이 숲에서 발견되죠.
the search from over 20 men
사람들로 좁혀졌어요.
in that area on the same day.
overlapping fingerprints
두 개의 지문입니다.
테이프에서 발견되었죠.
wrapped around Katie's neck.
cannot help the police
별로 도움이 되지 못합니다.
미궁에 빠졌을지도 모르죠.
this might have been the end of the road,
we can make the difference.
바꿀 수 있습니다.
our cutting-edge technology
수사를 도와달라는 요청을 받게 되죠.
질량분석 영상 기술을 사용합니다.
개량한 장비입니다.
analysis of fingerprints.
a UV laser at the print,
자외선 레이저를 쏴서
of the molecules from the print,
by the mass spectrometer.
the weight of the molecules --
they indicate that mass.
측정된 질량을 의미합니다.
forensically speaking.
더 불길한 것인지 표시해주죠.
to the evidence that we have
이 기술을 적용하고
of condom lubricants.
that enable us to even suggest
제안할 수 있습니다.
have obtained a search warrant
of condom in Dalton's premises.
콘돔을 찾아냈습니다.
also having records for sexual assaults,
성폭력 전과 기록이 있었기에
the less likely suspect.
enough to make an arrest?
충분한 정보일까요?
with our investigation.
요청받게 됩니다.
of other two very interesting molecules.
분자 2개의 존재를 찾아냈습니다.
and consume cocaine at the same time.
흡입할 때 형성되는 분자죠.
the effects of cocaine,
높인다고 알려져 있습니다.
on the state of mind
whilst perpetrating the crime.
실마리를 얻었습니다.
Thomson is a drug addict,
마약 중독자란 사실을 찾아냈으며
for psychotic episodes,
진료기록이 있었습니다.
the antidepressant was prescribed.
처방받았을 거예요.
the more likely suspect.
where these molecules are coming from,
이 물질이 어디서 온 건지
확실하지 않습니다.
can help us further.
these molecules are on a fingerprint.
있는지까지 알 수 있습니다.
corresponds to a mass,
by selecting each of those molecules,
소프트웨어에 입력하면
on a fingermark.
위치를 알 수 있습니다.
of the same mark --
이미지를 여러 장 얻을 수 있습니다.
of the same fingerprint --
동일한 지문 이미지를
that we have detected.
만들어 낼 수 있죠.
from different individuals,
is not identical,
가능성이 있죠.
to visualize those unique molecules
존재하고 다른 하나엔 없는
and not in the other one.
소프트웨어로 시각화합니다.
the two ridge patterns.
둘로 분리할 수 있습니다.
to identify one of the two fingerprints,
구분할 수 있게 되었기 때문입니다.
the two separate images
케이티의 사후에 채취한 지문을
on one fingerprint only --
집중하면 됩니다.
molecules that I've seen?
어디에 있을까요?
show me where they are.
소프트웨어에 물어보죠.
of the killer's fingerprint show up.
in the killer's print.
지문에만 존재하는 것입니다.
start matching very nicely
톰슨에 대한 수사 정보와
is still not good enough
여전히 충분하지 않아요.
of the same fingerprint,
산출해 낼 수 있으므로
of continuity and clarity?
of the fingerprint
지문 이미지를 얻었습니다.
through the database.
지문을 대조해볼 수 있습니다.
of the crime aren't real,
사건의 정황들은 실제가 아니에요.
이야기에 포함되어 있죠.
we've been confronted with,
that we can provide --
제공할 수 있는 것들입니다.
to provide the police.
that after nine years of intense research,
9년 동안의 집중적 연구 뒤에
to police investigations.
more about the suspect,
더 많은 걸 알게 되겠죠.
for criminal profiling.
새로운 시대가 열릴 거라고 믿습니다.
of behavioral patterns
특정 프로파일에 속한 행동 패턴을
to belong to a certain type,
but subjective evaluation,
of the fingerprint,
your routines,
the storytellers of our secrets
말해주는 이야기꾼입니다.

Why you should listen
Simona Francese is a Professor of Forensic and Bioanalytical Mass Spectrometry at Sheffield Hallam University in the UK. As she writes: "I have been fascinated by forensics since I was 17, and I was determined to pursue an educational route that eventually would enable me to contribute to secure societies. As always in life, nothing is straightforward. I enrolled in the chemistry course because it was the closest degree at the time that could lead me to where I wanted to be. I ended up doing a PhD and post-doctorate fellowships working with viruses and diseases. But I was always focused on my ultimate objective, and throughout I developed a strong expertise in mass spectrometry, which is an extremely versatile analytical technique. This was crucial.
"When I obtained my first lectureship, I had the freedom to build my own research, and I used mass spectrometry imaging to develop ways to profile individuals from their fingermarks, thus helping police with their investigations. What has the suspect been handling? What is their lifestyle? What did he do prior to or while committing the crime? These are some of the questions that the developed technology can answer, and we are working on providing additional information -- for example, on the pathological or pharmacological state of the individual, just from looking at their fingermark! A fantastic achievement for me, but the best accomplishment was keeping the focus for 14 years and remaining determined to finally be able to do what I have always been so passionate about."
