Waukesha County officials confirmed the wife of Radcliffe Franklin Haughton was among those killed in a fatal spa shooting in Brookfield Sunday.
Authorities said Haughton shot and killed three women, including his wife, Zina Haughton. Four others were injured.
Haughton then turned the gun on himself at the spa where his wife worked.
In a court filing, Zina Haughton said her husband thought she was cheating on him and threatened to kill her if she ever left him or called the police.
She said he threatened to throw acid in her face and burn her with gas.
She was granted a four-year temporary restraining order this month after her husband was arrested for slashing her tires.
