Fingerprint Technology Helps Solve Cold Case

After the abduction and sexual assault of a young girl in the small community of Cairnbrook, Pennsylvania, law enforcement searched tirelessly for the perpetrator as the community feared for children’s safety. But for nearly two decades, the offender eluded the FBI and the Pennsylvania State Police—until earlier this year. After the September 19, 1999 assault, [...]

TSA Launches Facial Recognition Pilot at Las Vegas Airport

The Transportation Security Administration will conduct a short term proof of concept in Las Vegas’ McCarran International Airport to examine how effective facial recognition technology could be at automating travelers’ identity verification, according to a recent publication from the Homeland Security Department.

The initiative during the month of July, dubbed Operation Independence Day, relied on more than 400 law enforcement agencies working on [...]

Military Fraudster Sentenced

The charity sounded like a worthy and patriotic cause—an organization that would send military families on Disney vacations and pay travel costs for families to see their loved ones graduate from boot camp in South Carolina and California.
