Four Twin Cities-area firefighters are searching for a father and son from Minnesota missing since planning to go for a hike in Colorado's mountains in April.
The firefighters began searching for 51-year-old Damian McManus and 18-year-old Evan McManus near Mount Evans Tuesday. They were set to wrap up their search Thursday but St. Louis Park, Minnesota fire chief Steve Koering says they're considering staying for an extra day.
Koering, who has been in contact with the group from Minnesota, says they haven't found any sign of them.
Colorado search and rescue teams have searched extensively for the men without much to go on. Their car was found at a campground near the base of the mountain but it's not known which trail they took. Heavy snow fell after they disappeared, erasing any footprints.
