Does LE really follow all the Internet stuff looking for clues? Dont laugh, but when watching 48hours they never look online for info- or they don't show us that. Does it vary according to department or manpower?
The internet is used more than ever before in crime solving.
Not so much for specific clues, but for witness/suspect information. Particularly nowadays social media such as Facebook and Twitter. Example...I worked a police action shooting this weekend. Within minutes of the incident an eyewitness was documenting what he saw on his facebook page. Within one hour of the post, he had over 40 comments posted to his wall. This led to identification of additional witnesses. One of which was a local business owner, who happened to mention she had exterior cameras on her building that may have captured the incident. These folks were easily identified, located & thir statements obtained for evidential purposes.
Another that comes to mind is a local man accused of Arson. While out of town with his wife, his residence caught fire & was a total loss. Investigation led to the discovery that he was essentially "tweeting" the entire night of the incident, detailing what he & his wife were doing at the time of the incident. "Eating dinner at John Doe's Restaurant...Just arriving to Cinema....Gassing Up, can't believe the price of fuel....stopping for a cocktail." His prior posting history was researched & it was shown that he had never, ever posted such as this. It was determined that he was offering an online play by play as an alibi, as he had set the home ablaze before he left.Investigation into his past revealed two additional, questionable house fires within the last 15 years or so.
There is a particular internet database that we use that is ridiculously scary. I can enter my own name (or the name of a suspect), & this site will offer an entire background, including financial history, addresses recorded in history for that person, phone numbers, email addresses issued to that person, vehicles registered (past & present), relatives, neighbors and likely associates, including their own entire history as well. Its an invaluable tool.
