Murder investigations and crime reports, as they
appear on television, have glamorized the field of forensic science. Truly, the
bloodstains, matching bullet shots and fingerprints look interesting on the TV,
but does this kind of evidence convict criminals in the real world? Read on to
From blood splatter to ballistics, everything in
crime scene evidence is now being challenged in the court. Stolen evidences,
foul-ups and evidences tampered with are common. Invalidated or improper
forensics, incompetence and fraud have caused many labs to shut down.
Improper software for DNA testing and analysis
have created a larger pool of 'citizens in suspect waiting' list, and naturally
aim mostly at relatives, due to partial DNA matches.
a) The 80,000 DNA
investigations in 2009 revealed that it is not a fool-proof way to validate a
b) In one out of every four
cases of the 285,000 fingerprint analysis, experts looked again and changed
c) Impact angles, sprays
and splatters, bloodstain patterns may have helped solve many cases, but
experts tend to go beyond what evidence supports.
Exponential growth is now taking place in the field of forensics, and the
future promises more miraculous feats. Let's have a look...
Morphometrics uses computer modeling software to identify craniofacial
characteristics and may help identify the skeletal remains of children younger
than 18 years of age.
Until now, DNA fingerprinting and analysis has been the best advancement of
forensic science. Science will now move beyond working on just DNAs and enter a
whole new aspect of providing more credible proofs. Simply put, bacteria
swabbed from an individual's fingers have a unique genetic profile, making it
easy to match and cross-check evidences. This 'personal bacteria' is
scientifically sound, and puts forth potentially reliable evidence to use.
With photo DNA, computer
forensic technicians can identify groups of images created by the same
individual, even if the images were edited or re-sized. This new technology can
be used effectively in the future to deal with child pornography.
dogs have been trained and used for decades to detect particular smells and
presence of bombs and drugs. Now, scientists in the UK have trained bees to
recognize specific smells. These trained bees stick out their tongues when they
catch a scent. Now that's something we would want to see...!!
25% of individuals between 18 and 25 years of age have at least one tattoo,
studies show. The prevalence of tattoos is even more among criminals and gang
members, which may prove to be handy in tracking such people. Now, a new
software has been developed, that may help identify even blurry images from a
Developed at the Pennsylvania State University,
the CSI 2020 is a portable device that may help detect chemicals emitted by
decomposing bodies. This may help locate buried corpses and estimate the time
of death almost immediately on-site, rather than waiting for the coroner's
