LONE TREE, Colo. -- It was a busy shopping day at Park Meadows mall on Tuesday, but one couple said three "Middle Eastern-looking men" still stood out among the crowd.
The couple photographed the men sitting at a table, but the couple said that's not what aroused their suspicion.
“As my wife and I were eating in the food court, we noticed three Middle Eastern men taking pictures,” the husband said.
The couple asked to remain anonymous but agreed to tell their story.
After the terrorist attack in San Bernardino, Calif., where the neighbor of the shooters failed to report suspicious behavior, this couple said they saw something and wanted to say something.
“I think what we need is to be aware of our surroundings and be vigilant because these kinds of things need to be reported because they were suspicious," the husband said.
The couple first notified a Lone Tree police officer.
“He said that he did notice the three individuals earlier taking pictures of the elevators and the mall and he questioned it, but he said since they weren't breaking the law he couldn't do anything about it,” the man said about the officer.
About 90 minutes later, the couple saw the three men again downstairs near the water fountain taking more pictures. The couple again found the officer.
“We were like, 'Yeah did you see him again?' He said, ‘Yeah, I really don't know what they are up to,” the wife said about the officer.
Frustrated, the couple said they left and contacted the FBI to report the behavior. The mall said it appreciated the couple’s efforts and said the couple did the right thing.
