Pasco relatives pray for miracle as search continues for missing Colorado mother
"TRI-CITIES, Wash. — Family of a Colorado mother missing since Thanksgiving want folks in Eastern Washington to be on the lookout, even as they try to figure out the circumstances around her disappearance.
They say it's a long shot, but she has family in Soap Lake, Wash. and authorities say her phone last pinged, or sent a signal, from an area near Gooding, Idaho.
The small city in south-central Idaho is on Interstate-84, and like the Tri-Cities, on the road between Woodland Park, Colorado and Soap Lake, Wash."
"There's no reason to think she intentionally is gone," said her cousin.
Kelsey was a pilot and flight instructor flying out of Pueblo, Colo.
Garretson says after learning about Kelsey's phone pinging from Idaho, the family let themselves hope.
"Her grandma isn't in good health so we thought, 'Well maybe'. In which case she could've driven right through the Tri-Cities," Garretson said."
