This is the third week we have featured these two. That shows you how badly authorities want to end their violent crime spree and how close they are to doing just that. It may take just one more call, just one more bit of information to put them behind bars, to keep someone from getting killed, and for you to earn yourself up to $1,000 reward.

Their pictures are probably familiar, by now. A black man and woman are seen on surveillance. One distracts while the other pulls a gun. "Over a period of the last six weeks, this couple has committed multiple armed robberies across the greater Chattanooga area," said Chattanooga Police Officer Mark Frazer. "The first of these robberies that we are aware of was July 19, and they have steadily continued to commit robberies in the exact same nature: carrying a gun, threatening employees, and it's just a matter of time before someone gets injured or killed."

They are working both sides of the Tennessee-Georgia state line. "We have Fort Oglethorpe, we have East Ridge, we have ourselves," Off Frazer recalled. "There are a lot of people looking for these criminals and we need your assistance."

The Crime Stoppers hotline received a number of calls with tips that could be helpful, but just a few more details are needed. "I need those people to call back," said Frazer. "Leave me a contact number so I can get a hold of you. These are anonymous phone calls. With just a little bit more information from you we can break open this case."

If you have not called, if you have been holding back, now is the time. Up to $1,000 is on the table. Help stop this duo before they or anyone else gets hurt. "Someone knows these people. Someone's related to these people. Someone saw them in their apartment complex or wherever they live," Frazer added. "We're close. A little help from the community, we will be even closer. Our priority number one is the safety and well-being of our community."

Be the hero. Tell us what you know. Earn cold hard cash for your good deed. Call Crime Stoppers: 423-698-3333

If you have called with info on this case before, call again. Leave some way for Officer Frazer to get back with you. Who you are will never be part of the equation.
