If you commute on one of the major interstate highways connecting Hampton Roads, chances are you pass one of the digital billboards everyday. And that's why the FBI is using them in their search for 26-year-old Devon Marrow - a fugitive who has eluded justice since last fall.

FBI Agent, Scott Baber says, "The billboard came to my attention from actually another agent in the office who had used this successfully to find one of his fugitives."

Community Outreach Specialist, Vanessa Torres says, "Our first fugitive went up October 24th and as a result of the many calls and tips that we have received we have reason to believe that the general public is just as concerned about the community as we are."

Law enforcement has been using the billboards for at least a few years now. In September of 2007, the Newport News sheriff's and police departments posted the picture of a slain fast food worker in hopes of finding her killer. Although that crime remains unsolved, this is an effective tool, affording investigators the opportunity to enlist the aid of just about everyone.

"You're looking at a volume of (in some cases) tens of thousands, hundreds of thousands of folks driving on some of the major interstate highways in greater Hampton Roads," said Jim Balestino, of Adams Outdoor Advertising.

That's a lot of eyes. And why the FBI considers the public to be one of their most valuable investigative tools.

If you have any information regarding the whereabouts of Devon Marrow, call the FBI at 455-0100. You can remain anonymous.
