"Troopers with the Utah Highway Patrol responded to the welfare check call and located Mueller, her two children and a nanny on Interstate 15 near Nephi, Utah. The children are safe and will be released to family. Mueller was taken to an area hospital for evaluation. The State Bureau of Investigation is currently investigating the incident.
