Crime is changing. More and more happens where no one can see the crime committed. More crime happens in broad daylight. More crime happens with witnesses that have no idea a crime is being committed. The criminal sits in a crowded train station or surrounded by business professionals sipping coffee at a local donut shop. As crime evolves, criminals are devising new ways to steal, to lure and to kill. How do they commit a crime unnoticed by witnesses? They use the Internet.

Tomorrow’s detectives must understand the Internet if they are going to find who did the crime. In The Charles River Killers, John Sanger understands the Internet, but he never dreamed the criminals would understand his internet technology better than he did.
