The search for a missing plane has been going on all week.

When 43-year-old Marcy Randolph didn't show up for work on Monday, her boss at The Advantage Mortgage Group in Phoenix knew something wasn't right.

"The lights were off. Her lights were off. Office lights were off. Her mother came by Monday morning and had the same concerns," said Michael Hays, Randoph's boss.

According to Phoenix police, at 10:43 Sunday morning, Randolph and Phoenix attorney William Westover, 54, took off from Deer Valley Airport. Westover was piloting a 1966 Cessna 182, possibly to Sedona, but authorities can say for sure since he never filed a flight plan.

"We are devastated by the not knowing what's going on and if she's hurt and we can't get to her," Hays said.

Over the last few days, crews from the Civil Air Patrol have been searching an area just south of Sedona but so far, there's been no sign of the missing plane.

"We miss her laugh, her conversation. It's a real empty feeling right now," Hays said. "We just hope they're in a place where they're comfortable enough and are just waiting for somebody to come find them."

The plane had a brown strip and the tail number is 2700Q.
