"It is a wonderful way for us to be able to catch these bad guys and get them out of our communities, if in fact that's where they are," said Special Agent Andrea Simmons with the FBI.

There are eight of the digital billboards scattered around the city, hawking everything from cars to the city itself. According to residents, they can be very effective.

"You look to some of those for the Amber Alerts and things like that and they work when children are missing so I think this is a great idea," said Gail Meredith, of east El Paso.

"I think it would be a great addition to, you know, something that's just going to have a car ad or something on it. But, you know, digital ones to put all that information up, I think it's a great idea," said Juan Aguirre, of east El Paso.

According to Clear Channel, the digital billboards reach over 260,000 El Paso residents every day. It's a captive audience the FBI hopes will help them catch their most dangerous suspects.

"They may be drug fugitives, they could be, if we suspected some sort of terrorist activity and a person who is a fugitive, or had some sort of terroristic ties here, we could put that information up," said Simmons.

The ads will have a 24-hour hotline to offer anonymous tips and, for some, that's a key element in helping authorities catch the people listed.

"If they're looking for somebody, you know, somebody calls, they're going to after him, 'Oh, you know who he was,' but this would keep it more anonymous I think. It would help a lot," said Aguirre.

The FBI tested billboard messages in Philadelphia this past September. A month later, three of the 11 fugitives shown were captured as a direct result of the extra publicity. The agency will put out information on wanted suspects in the El Paso area on a case-by-case basis.
