The Texas 'Black Widow' Case: Man Shot Dead in Bed by Own Wife

— -- intro:It was a crime that drew national attention. A Keller, Texas, man was found dead, and the only person who knew what happened was his wife.

At his home in an upscale gated community, Gregg Williams was shot in the head and later died. Police took their only witness, Williams’ wife Michele Williams, to headquarters, where she told them an intruder in black clothing hit her and shot her husband.

But soon after arriving at the home, police became suspicious.

Confronted by police, Michele Williams changed her story. She then said her husband committed suicide.

Police released Michele Williams, but she was later arrested and then indicted by a grand jury in the murder of her husband. Michele Williams accepted a plea deal in which she pleaded guilty to tampering with evidence and deadly conduct in her husband’s shooting.

However, before she could be sentenced, she granted an interview to a national TV crime show. After telling the show she was an innocent woman, her plea deal was revoked, and she went to trial for her husband’s murder.

Gregg Williams was into martial arts and bodybuilding and ran a successful computer-tech business. He and Michele Williams each had two marriages behind them.

The two were renting the big home with a pool in the yard and matching luxury cars in the garage.

Lee O’Brien, Michele Williams’ son from a previous marriage, said Gregg Williams was a good catch for his mother. O’Brien said he worked for Gregg Williams until he was fired.

“She found the golden goose: money. He's got the money. He's got the party lifestyle. He's accomplished, and she's head over heels,” O’Brien told “20/20.”

Michele Williams was spending her husband’s money as fast as he could make it, O’Brien said. But there was a dark side to Gregg Williams, according to O’Brien.

O’Brien said he once got into a fight with Gregg Williams and that dangerous-looking friends would show up to parties thrown by his mother and Gregg Williams.

“You've got gangsters that you can see the outline of a pistol in the back of their pants at these parties,” O’Brien said. media:26194619

quicklist:3title:Michele Williams Is Questionedtext:As the only witness to her husband’s death, Michele Williams was brought to the police station for questioning.

She told police Det. John McGrew that a mysterious intruder dressed in all black and speaking with a thick, country accent broke into her home. She said the intruder hit her so hard she blacked out for several seconds.

Williams said the intruder shot her husband once in the head and then ran out the back door. She had a bruise on her cheek from the supposed attack, but police said the evidence at the crime scene wasn’t adding up to Williams’ story.

“That scene was basically mostly lies, I believe,” McGrew told ABC News’ “20/20.”media:26245609caption:use

quicklist:4title:A Closer Look at the Crime Scene text:Inside the Williams’ home, police investigators found a gun belonging to Gregg Williams, a single shell casing, and a long wrench all left by the back door.

“That’s so nobody can actually overlook those, so that they're obvious,” Deputy Chief District Attorney Jack Strickland told “20/20.”

Police also took a closer look at the door that Michele Williams said the alleged intruder got in through. They determine that whoever jimmied the door open was doing it for show. The pry marks on the door could only have been made when the door was already open.

“It was obvious to the crime scene investigator that this door was open when that damage was created,” Keller Police Capt. Brenda Slovak, the lead investigator, told “20/20.”media:26192252

She told police that Gregg Williams shot himself and that she attempted to cover it up to protect the couple’s daughter. She said she wiped her husband’s hand and the gun with disinfecting wipes and flushed them down the toilet.

Michele Williams said she also scratched around the door frame to make it look like a burglary and then hit herself in the face with the wrench police found at the crime scene so she would have an injury to support her claim of there being an intruder.

Police released Michele Williams later that day on Oct. 14, 2011.

The next month on July 4, 2012, Williams was indicted by a Tarrant County grand jury on charges of murder and tampering with evidence in the shooting death of her husband.

Later in October 2013, Williams, in a deal with the prosecutor, pleaded guilty to deadly conduct and tampering with evidence.

Prosecutor Jack Strickland said they decided to enter into the plea deal because it appeared Williams might have asked for a lawyer during her interview with police. He worried that a judge might throw out the interview as evidence and that a jury would never hear Williams’ changing story.

“You don’t know how a court is going to rule. Does that mean she was asking for a lawyer? Does that mean that her interview should stop? Does that mean that anything post that remark is going to be suppressed?” Strickland said.

Williams told the court she was pregnant with twins, so her sentence was delayed until after her due date. She was scheduled to be sentenced to a recommended 18 years in prison in April 2014.media:26191356
