The FBI issued an alert to Wyoming and Colorado law enforcement that military families have been confronted at their homes by Middle-Eastern males. Military members have also found threatening notes on their windshields. The agency has been unable to connect these incidents or identify the men involved, but it’s taking precautions to warn the local military community.

Here’s the FBI’s report in full.

(U//FOUO) In May 2015, the wife of a US military member was approached in front of her home by two Middle-Eastern males. The men stated that she was the wife of a US interrogator. When she denied their claims, the men laughed. The two men left the area in a dark-colored, four-door sedan with two other Middle-Eastern males in the vehicle. The woman had observed the vehicle in the neighborhood on previous occasions.

(U//FOUO) Similar incidents in Wyoming have been reported to the FBI throughout June 2015. On numerous occasions, family members of military personnel were confronted by Middle-Eastern males in front of their homes. The males have attempted to obtain personal information about the military member and family members through intimidation. The family members have reported feeling scared.

(U//FOUO) To date, the men have not been identified and it is not known if all the incidents involve the same Middle-Eastern males. If you have any information that may assist the FBI in identifying these individuals, or reporting concerning additional incidents; in Colorado please contact the FBI Fort Collins Resident Agency at 970-663-1028, in Wyoming please contact the FBI Cheyenne Resident Agency at 307-632-6224.
