Here is the person I love. He's dying.

Her husband, a decorated military officer, shot in the dark of night.

It was an execution.

Was this some sort of hit?

He was in special forces. There must have been something at work.

That's what police thought too, until they learned about the secret life of this husband and wife.

They would meet couples on the internet.

Was there a forbidden affair?

They were probably meeting for sex about four times a week.

And did it lead to murder?

She is absolutely cold blooded.

Soon, there'd be questions for a mother and daughter.

It was another shock.

I'm Lester Holt, and this is Dave Lye.

Here's Keith Morrison.

The wind in the northern prairie sweeps across a vast flat land.

Sings through sparse woodlots.

Howls a dirge around the grave markers in a military cemetery a few miles south of the Canadian border.

The final resting spot for a few dozen veterans, many of whom died in combat.

Including Major David Shannon, who lost his life in 2002.

His mother surely goes there to visit and remember.

His sister Brenda too when she's in town.
