Crews may start searching again next month for a St. Louis Park father and son missing in Colorado.
Fifty-one-year-old Damian McManus and his 18-year-old son Evan haven't been seen since early April.
They took a spring break trip to Colorado and planned to hike near Echo Lake west of Denver.
According to the Clear Creek Courant, the sheriff's office is planning a large scale search for the two around May 10.
It will include search dogs and about 100 trained volunteers.
