A "48 HOURS" INTERVIEW WITH THE WIFE OF A MILLIONAIRE SHOT DEAD TURNS THE CASE UPSIDE-DOWN - IS THERE MORE TO THE STORY?

"48 HOURS: TEMPTATION IN TEXAS"

TUESDAY, JUNE 2 AT 10:00 PM, ET/PT

A "48 Hours" interview with the wife of a millionaire shot dead turned the case upside-down. Was there more to the story of what happened? Peter Van Sant and 48 HOURS return to the investigation in the death of a businessman and the overriding question of whether he was killed by an intruder, as his wife said, or if he was killed by someone else, in an updated edition of "Temptation in Texas" to be broadcast Tuesday, June 2 (10:00 PM, ET/PT) on the CBS Television Network.

The case exposed a web of strained relationships and allegations of extramarital affairs. It was also upended when the key witness, the victim's wife, Michele Williams, changed her version of events, including in an interview with 48 HOURS. That interview with Van Sant would become part of the evidence used during trial.

"I've been trying cases for more than 49 years. And Michele Williams' case has to rank up there as one of the most bizarre that I've been involved in. It had murder. It had sex. It had contradictions. It had a little bit of everything," said Tarrant County prosecutor Jack Strickland.

On Oct. 13, 2011, Greg Williams was shot dead in his home in a wealthy Dallas suburb. In the early morning hours, Michele called police and said her husband had been shot by an intruder, and she had been smashed in the face as the man fled.

"Greg treated me like a queen," Michele told Van Sant. "I was his princess."

But who would want to kill Greg Williams?

As the police investigated the death, Michele Williams confused matters by changing her story. After saying he was shot by an intruder, Michele told police Greg killed himself and she cleaned up to protect their young daughter from knowing her father committed suicide.

Police believed that Michele was the killer but with little physical evidence after an exhaustive investigation, the district attorney was prepared to offer her a plea deal - pleading guilty to tampering with evidence and "deadly conduct." For Williams, it was a way to remove the risk of going to trial and get a lighter sentence in order to get back home with her daughter sooner. What seemed like a closed case was far from it. Just before the plea deal was completed, in an interview with 48 HOURS, Michele changed her story once again.

"Did you murder your husband, Greg?" Van Sant asked Williams.

"No, I did not," she said, adding that she had an idea who the real killer was.

"We used the 48 HOURS tape to demonstrate not only that she had changed her story yet again, but she'd added - because she couldn't leave well enough alone - an additional fact that 'not only was it an intruder, I think I know who it was.' OK, that was just beyond the pale. So the tape was very beneficial to us," said Strickland.

And then the wife of Greg Williams' best friend, Brynn Fletcher, weighs in with startling revelations about her husband's death, also by a gunshot.
