Audio/Video Forensics Benefits Diverse Investigations

The ability to enhance images extracted from video and digital cameras has helped solve many investigations — from fleeing bank robbers caught on camera to actual crimes recorded on tape. Chicago RCFL Examiner Paul Rettig is applying his video forensics skills to aid two very different investigations — one for the National Hockey League and another involving a violent criminal who not only robs but chokes his victims

The ability to enhance images extracted from video and digital cameras has helped solve many investigations — from fleeing bank robbers caught on camera to actual crimes recorded on tape.Chicago RCFL Examiner Paul Rettig is applying his video forensics skills to aid two very different investigations. The first investigation involves a criminal nicknamed the "Oak Park Choker" who is preying on women in an affluent suburb of Chicago. One victim fought her attacker and was able to provide police with a physical description. Examiner Rettig conducted video forensics on surveillance images capturing a man using a stolen ATM card. Police released the enhanced images to the media and have enlisted the public's help with identifying the culprit(s) who remains at large. 

In a totally different investigation, Examiner Rettig volunteered his time to assist the National Hockey League who was searching for what press reports described as "the most famous hockey puck in Chicago's history." A $50,000 reward was offered for its return and officials with the Hockey Hall of Fame also wanted answers as to how nobody saw the winning puck — which gave Chicago its first Stanley Cup victory in 49 years — simply vanish before a packed arena. Examiner Rettig enhanced digital pictures used in the investigation — click here to read the full story featured on ESPN's website or click here to watch a video clip.
