Crime scene investigation is nothing new. Advances in forensic investigations over the past 20 years have been astronomic. Scientists have been using DNA to investigate crime scenes and potential suspects with great success. DNA can tell a story more accurate than any other scientific method to date. However, DNA testing for use in criminal profiling has just reached an epic milestone. Researchers are now saying that soon, the investigative process will be improved by the implementation of DNA in way that has not yet been used.
By using a single piece of DNA, investigators will be able to create an entire criminal profile based on the specs gleaned from a single specimen. In fact, this technology will allow a profile with staggering accuracy to be developed. Scientists will be able to generate the face and the characteristics of a suspect before a suspect is even present in the investigation. The key to understanding this method is to understand DNA and how it works on a cellular level.
Since living things are simply large, grouped together structures of cells reproducing themselves over and over, taking the body back down to a singular cell from which all the subsequent DNA propitiated itself is the basis by which this new science operates. A technology, much like that which is used in computer-generated age progression used for determining the characteristics of missing children, is now being perfected to do the same on a cellular level. Basically, science can take the cell and determine how that particular cell will regenerate itself repeatedly.
Once this is determined, computer technology can generate a photo of the person from whom the DNA specimen originated. The crime rate is currently at 386.9 out of 100,000 people. While these numbers are statistically less than previous years, this does not mean that crime stands any chance of disappearing all together. Ech day, lives are lost unnecessarily and in many cases, remain unsolved even with the advanced technology and investigative techniques that are now commonplace. Situations like these drive up costs to the tax payers as well as put even more anxiety on the families and loved ones of crime victims. Police and the FBI must spend valuable resources to locate the criminals and assess the situation for further investigation.
Often, this process is counter productive when there is a struggle to identify leads. The new DNA technology will now fine tune the investigative process on behalf of the workers who endeavor to find the answers they need. In addition, society at large is impacted, as technology like this is likely to decrease the amount of dangerous criminals who get away with the crimes they commit. They will now be easily identifiable before investigators even have the opportunity to begin a suspect list. Mark Shriver, an anthropologist fronting the movement being researched at Pennsylvania State University has recently published a synopsis of the team’s tireless efforts, indicating that the findings will most likely lead to DNA face generation in the near future. By isolating miniscule parts of the DNA that correlate with facial production, scientists now feel that soon their findings will be a reality in the field of criminal profiling.
