FORT WORTH -- The Keller mother who initially told police that her husband had been killed by intruders, then changed her story to say he had committed suicide, has been indicted in the case.Michele Williams, 43, was indicted Wednesday by a Tarrant County grand jury on charges of murder and tampering with evidence in the Oct. 13 shooting death of her husband, Gregory Williams, 40, in their upscale Keller home.Michele Williams, who moved to Flower Mound just weeks after the crime was committed, remained free Thursday on $85,000 bail, which she posted shortly after her arrest in January. Initially, she was in custody with bail set at $522,000, but a judge later lowered it.Neither Michele Williams nor her attorney Stuart Parker of Dallas could be reached for comment.Gregory Williams' sister, Michelle Williams of Dallas, said, "I don't understand why it took so long. It just upsets me that she's allowed to be running around here."Gregory Williams was the owner of a computer programming company in North Texas and his wife was the officer manager. Michele Williams also had operated a frozen yogurt shop in far north Fort Worth across the street from Keller Central High School.Michele Williams initially told police that a man dressed in black entered her Keller home through a back door in the 1400 block of Jacob Avenue, hit her in the head and shot her husband in their bedroom. The couple's 4-year-old daughter was in the house at the time.Investigators found scratches around a doorknob and deadbolt lock at a back door.Michele Williams also had a bruise on her cheek.But later, authorities found a .45-caliber handgun, a shell casing and a wrench near the back door, away from Gregory Williams' body. In addition, investigators noted that the television was so loud in the bedroom that an officer had to turn it down to converse with other officers.Hours later, she changed her account, saying her husband committed suicide. She told police that she had lied to protect their daughter from finding out that her father had killed himself.She also told police that she had hit herself with the wrench and had used a screwdriver to make the marks on the back door, according to a search warrant affidavit.But the affidavit noted that she may have sedated her husband and turned up the volume of the television to cover up the sound of a gunshot, according the affidavit.Williams also may have used the Internet to research how to stage a crime scene, the affidavit stated.Domingo Ramirez Jr., 817-390-7763Twitter: @mingoramirezjr.
