The Tarrant County medical examiner says preliminary results indicate a man found shot dead in his home Thursday was the result of a homicide, not suicide.
Gregory Williams, 40, was found shot to death early Thursday morning after his wife, Michelle, told Keller police that someone had broken into their home, struck her and fatally shot him before leaving.
After a police dog determined there had been no other people present, the woman changed her tune.
She then said that her husband had killed himself while she was in another room with their daughter. She said, in an attempt to conceal the suicide from their child, she staged a violent home invasion.
Michelle told police she hit herself in the face with a wrench, cleaned her husband's hand and gun and even tampered with a back door to make it look like someone had invaded their home.
Keller police have not made any arrests in connection with the man's murder and said they are waiting on key pieces of forensic evidence in order to obtain an arrest warrant.
Investigators told NBC 5 that Michelle is the only suspect at this time.
