Archaeologists will use ‘CSI’-like technology to study 2500-year-old remains near Athens

More than 2,500 years ago, an Athenian nobleman named Cylon — the first recorded Olympic champion — tried to take over the city of Athens and install himself as its sole ruler.

According to Thucydides and Herodotus, Athenian and Greek historians who wrote about the coup, Cylon enticed an army of followers to enter the city and lay siege to the Acropolis.

They were defeated, but Cylon managed to escape.

Now archaeologists in Athens believe they may have found some of the remains of Cylon’s army in a mass grave in Phaleron, four miles south of downtown Athens.

The discovery of the 80 skeletons of men is “unequaled” in Greece, said site project director Stella Chrysoulaki.

The men, young and well-fed, were found lying in the unmarked grave in three rows, some on their backs while others were tossed facedown on their stomachs.

All of

Technology offers new ways to lift crime scene latent prints

The new technique is not limited to a crime laboratory setting, but can be utilized at the crime scene

By Dena Weiss, Faculty Member, Criminal Justice at American Military University

In a crime scene examination, investigators are responsible for collecting items of evidence and processing the items for possible latent prints. Latent prints are left by chance on a surface when someone touches an item. The latent print represents a partial impression of the unique ridge pattern located on an individual’s fingers and palms.

Evidence that is collected is categorized as nonporous, semi-porous or porous. Nonporous evidence can include weapons, vehicles, glass bottles, and plastic bags. Semi-porous evidence can include magazines, varnished wood, and some plastic materials. Porous evidence includes paper, unfinished wood, and fabrics.

Latent prints on nonporous surfaces can pose a challenge for investigators because they are very fragile. They consist of 99% water and approximately 1% amino acids, lipids, and other

Why police should use new crime scene mapping technology

In crime scene work, good photos are necessary to tell the visual story of what took place. Photos may lack context, however, making a diagram necessary. Rooms with alcoves, made in odd geometric shapes or just plain not square don’t always display well with pictures alone.

Mapping a crime scene factually takes time. It can be the most time-consuming and tedious part of some investigations. But creating an accurate diagram helps to preserve the location of evidence and aids in putting it into context. Diagrams convey scale and distance in a way that photos often cannot capture.

Criminal Face Recognition Technology Raises Controversy

New innovations in technology have improved crime scene investigation. Probably one of the most innovative yet would be the use of face recognition technology to identify and determine whether or not a suspect is a criminal. However, experts are not quite keen on the criminal face recognition technology and are questioning its accuracy.

Similar to most kinds of biometric database, face recognition technology is used to scan and record data of not only criminals but normal residents as well. A research from the Shanghai Jiao Tong University in China has published a system that could allegedly determine whether or not a scanned photo belongs to a criminal.

According to CNN, the FBI was able to launch a similar system of face recognition technology in 2015 which was used to ease their photo searches on a daily basis. The aim of this
