Digital billboards featuring sketches of the suspect are running in the four states where attacks occurred including Virginia and Maryland.
Police have also set up a website about the case at EastCoastRapist.com -- it contains maps, composite sketches and very specific details about how this man operates.
The same individual is believed responsible for a dozen separate attacks that targeted 17 women. The most recent occurred in Woodbridge, Va., in 2009, where he was almost caught when a victim was able to send a text message to her mother calling for help.
All the attacks have been linked by DNA, but investigators say they need someone to recognize and identify him.
