Cold case unit uses new technology to solve homicides

KERRY O'BRIEN, PRESENTER: Major developments in DNA and forensic technology in the past five years have revolutionised the way criminal investigators do their work. With more difficult crimes like homicide, detectives are now producing some spectacular results, including the arrest last week of a Victorian man for the murder of his wife 22 years ago. But it's NSW that has the biggest number of cold case homicides on its books: 420 murders dating back to 1975. A new unsolved homicide unit has now been set up to try and clear the backlog, and with 35 full time investigators, police say there are a lot of people out there who should be very nervous.
