It has been about three weeks since Bentley, 7, and Karley Dunkelberger, 9, were last seen. Authorities say they may be in Colorado and that two are considered to be in danger.

The Colorado Bureau of Investigation sent out an alert for residents to be on the lookout for the missing brother and sister who are believed to be in the company of their parents, 42-year-old Dennis and 37-year-old Rebecca Dunkelberger. Authorities say both parents, “have a history of drug use and violent tendencies when together.” They also said Rebecca suffers from a cognitive disorder. The family was last seen in a black Kia Sorento with Michigan license 4-L-U-Z-9-0, similar to the one pictured below.
