Rescuers on the Big Island continued their search Saturday for a 67-year-old Michigan man missing since he left to hike a Mauna Kea trail as a storm approached three days prior.

Brian Murphy told his traveling companion he was going to the snowy dormant volcano on the Big Island.

He later signed in at the Mauna Kea Visitor Information Station — which is at 9,200 feet — around noon Wednesday and spoke to an employee about going about a mile up the Humu'ula Trail. The old footpath climbs about 3,800 feet up the mountain, up to Lake Waiau at 13,020 feet.

Two hours later, a cold front hit the Big Island, dropping about a foot of snow on the summit. The storm created a blizzard with winds of up to 70 miles per hour.

The Plymouth, Mich., father of two and grandfather of five was declared missing at 8 p.m. Wednesday.

Hawai'i County's Chopper 1 searched the 9,000- and 10,000-foot area of the mountain the next day but stopped due to adverse weather. The search for Murphy continued Friday and Saturday under clearing skies.
