This special two-part edition of 48 hours continues.

Multimillionaire Darren Mack is facing life in prison

for the murder of his beautiful sexy wife, Charla.

There is a mountain of incriminating evidence against Darren.

Is this the end of the story?

Not by a long shot.

When a sniper opened fire on the morning of June 12th at 11.5 in downtown Reno.

The judge was rushed to the hospital in critical condition.

No one could have imagined the horror that had taken place only a few miles away two hours earlier.

The In an upscale condominium complex, a woman had been brutally stabbed to death in a garage.

Nobody knew what was going on, and nobody had put the two events together. Nobody disputes that Charla was there that morning in Darren's garage to drop off her daughter.

Charla was so afraid of Darren, so most people think he must have made some sort of promise

that he was going to end the fight over their divorce if she would just come in and talk to him.

That is the only reason most people think she would have gone into that garage.

When I first heard that Charla had been killed,

it was like somebody punched me in the chest.

And you're thinking, it just happened and maybe,

maybe somehow if you can get to her and turn back time real fast,

you can save her.

At one point I think the max were a happily married couple. They did enjoy an alternative sort of lifestyle.

They were swingers.

They went to sex clubs and sex parties.
