Alissa Marie McCrann was 37 when she vanished while running near Multnomah Falls in the Columbia River Gorge on Saturday, December 19, 2015. A Portland resident from the Powellhurst-Gilbert neighborhood, she was a mother to a 13-year-old son and lived with her Korean parents. That morning she had run once, then left again in her Mazda CX-7, believed to be headed for the Franklin Ridge Loop Trail. She was reported missing on Monday, December 21 after failing to show up for work at Sunshine Dairy; her car was found the next day in the Multnomah Falls parking lot.

A couple reported speaking to a woman matching Alissa’s description on a trail near Franklin Ridge at about 3 p.m. on the day she disappeared. They said she wore running clothes and shoes but had no food, water, or cold-weather gear; when they urged her to turn back she ran down the trail, apparently trying to stay warm. More than 100 searchers covered over 150 miles of trails, with sniffer dogs and an aircraft, but heavy snow and dangerous conditions—over a foot of fresh snow at higher elevations—forced officials to suspend the official search on December 24. A volunteer search in January 2016 covered more than 80 miles of trail without producing new clues.

No trace of Alissa has been found. Does anyone who knew Alissa or who was in the Multnomah Falls area on December 19, 2015 have information that could help?
