When we last left off, night had fallen over the White Mountains.

21-year-old Mara Murray had just vanished without a trace.

It was almost as if the nursing student was seemingly swallowed up by the dark of

night, evaporating into the New Hampshire wilderness like she was never there at all. The only sign

that witnessed Butch Atwood, a local school bus driver who talked to Mara before she disappeared,

hadn't completely imagined his interaction with

the slight brown-haired girl with dimples was her black Saturn that sat crumpled in an unsuspecting

snowbank abandoned along a stretch of Route 112 in Haverill, New Hampshire.

The engine was cold.

The driver's side door opened.

There was no sign of the young woman who had been behind the wheel.

Only ten short minutes elast since Butch saw Mora alive on the side of the road. But in that

minuscule window of time, a young woman's entire life and future was erased, and a huge mystery was beginning to take shape.

More was like a ghost, gone, but so freshly gone that her presence still hung in the air.

Moore's disappearance would fracture her family, divide investigators, and launch a mystery

that had a grip on anyone who studied the case, and it still hasn't let go.

For 20 years, a quiet New Hampshire town has carried the weight of one of New England's most haunting

cold cases. You're listening to Mystery and Murder Analysis by Dr. Phil. This is Into Thin Air,

the disappearance of Mora Murray.

The Search and Secrets.

When Mora first vanished, nobody could agree on what kind of story they were dealing with.

Had a crime been committed?
